    abstract = "{Introduction: The German Registry of central serous chorioretinopathy (CSC) collects data on CSC patients in a nationwide multicenter approach to analyze epidemiology, risk factors, clinical presentations, as well as diagnosis and treatment patterns. Methods: In this multicenter cohort study, patients with CSC were enrolled in nine tertiary referral centers in Germany between January 2022 and June 2023. After consenting to the study, demographic data, risk factors, reported symptoms, best-corrected visual acuity (BCVA), funduscopic findings, disease severity, and diagnostic and treatment decisions were recorded and analyzed. Results: A total of 539 eyes of 411 CSC patients were enrolled in this study including 308 males (75\\%) and 103 females (25\\%). Patients were predominantly of Caucasian origin and had a mean age of 55.5 years (IQR 41.0–70.0). 28\\% of eyes were classified as acute (\\<4 months duration) CSC, 28\\% as chronic (\\>4 months duration) CSC, 21\\% as inactive CSC, 11\\% as chronic atrophic CSC, and 12\\% as CSC with secondary CNV. 128 patients (31\\%) demonstrated bilateral CSC. The most common risk factors reported were psychological stress (52\\%), smoking (38\\%), arterial hypertension (38\\%), and a history of or current use of steroids (30\\%). Most frequently encountered symptoms included decreased visual acuity (76\\%), metamorphopsia (49\\%), relative scotoma (47\\%), blurred vision (19\\%), and dyschromatopsia (9\\%). The mean logMAR BCVA on initial examination was 0.2 (≈20/30, IQR 0.2–0.4) but showed significant variation with a tendency of lower BCVA in chronic cases. At the baseline visit, 74\\% of the overall cohort received no treatment, while 19\\% underwent local treatment and only 2\\% underwent systemic treatment. Of the local therapies, anti-VEGF injections were the most frequently performed procedure (33\\%, mainly for secondary CNV), followed by micropulse laser (28\\%), focal nonpulsed laser (23\\%), verteporfin photodynamic therapy (14\\%), and nonsteroidal anti-inflammatory eye drops (2\\%). Among intravitreal anti-VEGF agents, aflibercept was used most frequently, followed by bevacizumab and ranibizumab. Conclusion: This registry represents one of the largest cohorts of European patients with CSC to date. Patient age and the proportion of women were higher than expected and bilateral active disease was lower than anticipated, highlighting that neither age nor gender should be overemphasized when diagnosing CSC. Therapeutic interventions are heterogeneous and include verteporfin photodynamic therapy, micropulse laser, and anti-VEGF injections in case of secondary CNV. }",

Two AMD mouse models, apolipoprotein E knockout (ApoE−/−) mice and NF-E2-related factor-2 knockout (Nrf2−/−) mice, and their wild-type mice underwent monthly ophthalmic examinations including FLIO from 3 months of age. After euthanasia at the age of 6 or 11 months, blood plasma was collected to determine total antioxidant capacity and eyes were enucleated for Oil red O (ORO) lipid staining of chorioretinal tissue.    In FLIO, the mean fluorescence lifetime (τm) of wild type shortened with age in both spectral channels. In short spectral channel, τm shortening was observed in both AMD models as well, but its rate was more pronounced in ApoE−/− mice and significantly different from the other strains as months of age progressed. In contrast, in long spectral channel, both model strains showed completely opposite trends, with τm becoming shorter in ApoE−/− and longer in Nrf2−/− mice than the others. Oil red O staining at Bruch's membrane was significantly stronger in ApoE−/− mice at 11 months than the other strains. Plasma total antioxidant capacity was highest in ApoE−/− mice at both 6 and 11 months.    The two AMD mouse models exhibited largely different fundus fluorescence lifetime, which might be related to the different systemic metabolic state. FLIO might be able to indicate different metabolic states of eyes at risk for AMD.    This animal study may provide new insights into the relationship between early AMD-associated metabolic changes and FLIO findings.  }",

ABSTRACT = {The purpose of this study was to investigate the possibility of implementing an artificial intelligence (AI) approach for the analysis of fluorescence lifetime imaging ophthalmoscopy (FLIO) data even with small data. FLIO data, including the fluorescence intensity and mean fluorescence lifetime (τm) of two spectral channels, as well as OCT-A data from 26 non-smokers and 28 smokers without systemic and ocular diseases were used. The analysis was performed with support vector machines (SVMs), a well-known AI method for small datasets, and compared with the results of convolutional neural networks (CNNs) and autoencoder networks. The SVM was the only tested AI method, which was able to distinguish τm between non-smokers and heavy smokers. The accuracy was about 80%. OCT-A data did not show significant differences. The feasibility and usefulness of the AI in analyzing FLIO and OCT-A data without any apparent retinal diseases were demonstrated. Although further studies with larger datasets are necessary to validate the results, the results greatly suggest that AI could be useful in analyzing FLIO-data even from healthy subjects without retinal disease and even with small datasets. AI-assisted FLIO is expected to greatly advance early retinal diagnosis.},

abstract = { PURPOSE: Central serous chorioretinopathy (CSC) is a disease presenting with detachment of the neurosensory retina and characteristic focal leakage on fluorescein angiography. The spontaneous remission rate is 84% within 6 months. In this study, the efficacy of selective retina therapy (SRT) was examined in patients with therapy refractory persistent acute CSC defined by symptoms for at least 6 months and persistent subretinal fluid (SRF) despite eplerenone therapy. MATERIAL AND METHODS: This is a prospective, monocentric observational study in 17 eyes (16 patients, mean age 42 years, 2 female). SRT was performed with the approved R:GEN laser (Lutronic, South Korea), a micropulsed 527-nm Nd:YLF laser device, with a train of 30 pulses of 1.7 μs at 100-Hz repetition rate at the point of focal leakage determined by fluorescein angiography (FA) at baseline (BSL). Visits on BSL, week 4 (wk4), and week 12 (wk12) included best corrected visual acuity (BCVA, logMar), central retinal thickness (CRT) on spectral domain optical coherence tomography (SD-OCT), and FA. Statistical analysis was performed by pair-by-pair comparisons of multiple observations in each case with Bonferroni correction for multiple testing. (IBM SPSS Statistics 25®). RESULTS: Mean CRT at BSL was 387.69 ± 110.4 μm. CRT significantly decreased by 106.31 μm in wk4 (95%-KI: 21.42-191.2; p = 0.01), by 133.63 μm in wk12 (95%-KI: 50.22-217.03; p = 0.001) and by 133.81 μm (95%-KI: 48.88-218.75; p = 0.001) compared to BSL. Treatment success defined as complete resolution of SRF occurred at wk4 in 7/17 eyes (35.3%) and at wk12 in 10/17 eyes (58.8%). Re-SRT was performed in 7/17 eyes (41.2%) after an average of 107.14 ± 96.59 days. Treatment success after Re-SRT was observed in 4/6 eyes (66.6%, 12 weeks after Re-SRT). Mean BCVA did not change significantly from BSL to any later timepoint after adjusting for multiple testing. Notably, eyes with treatment success showed better BCVA at all timepoints and gained more letters compared to failures. CONCLUSION: Single or repetitive SRT may be an effective and safe treatment in 2 of 3 patients suffering from acute persistent CSC after 6 months of symptoms or more. We observed complete resolution of SRF in around 60% of eyes 12 weeks after first SRT treatment and also 12 weeks after Re-SRT treatment in eyes with persistent or recurrent SRF. Results on the long-term course after SRT are still pending.},

abstract = {MHz-OCT systems based on FDML swept laser sources combined with the massive parallel processing capabilities of modern computer hardware enable volumetric imaging, processing and stereoscopic display at video rates. The increasing image quality and speed might enable new fields of application where the volumetric OCT completely replaces stereoscopic microscopes instead of being a mere supplement. Aside from the depth resolving capability, a particular advantage is the ability to display a whole image volume from arbitrary points of view without the need to move the actual microscope or to rotate the patient’s eye. Purely digital microscopy is already offered as alternative to traditional through-an-eyepiece surgical microscope. We explore the use of virtual reality to present digital OCT microscopy images to a trained surgeon, carrying out a series of surgical procedures ex-vivo on a porcine eye model.},

Abstract = {Purpose: To compare the efficiency and safety of two
phacoemulsification systems, the Infiniti with intelligent
phacoemulsification (IP) and the Centurion without IP, in
terms of intraoperative metrics of phacoemulsification and
the occurrences of adverse events and intraoperative tip
obstruction.
Design: Comparative case series.
Methods: A consecutive series of 340 eyes (151 eyes with
the Infiniti, 189 eyes with the Centurion) was evaluated. A
2.4 mm sclerocorneal incision was used with the Infiniti, and
a 2.0 mm incision was used with the Centurion.
Phacoemulsification of the nucleus was performed using
the phaco chop technique, with the IP function of the
Infiniti turned on and the IP mode of the Centurion turned
off. From among the parameters displayed on the panels of
both devices, ultrasound (US) time, cumulative dissipated
energy (CDE), aspiration time, and estimated balanced salt
solution (BSS) aspiration volume were investigated and
compared between the devices. Results: A comparison of all
subjects found significant differences between the two
devices in mean CDE (p=0.02) and mean aspiration time
(p=0.003), but not in mean US time (p=0.43) or mean
estimated BSS aspiration volume (p=0.07). For grade 3
nuclei, all parameters of mean US time (p=0.0044), mean
CDE (p ≤ 0.001), mean aspiration time (p<0.001), and mean
estimated BSS aspiration volume (p=0.001) showed
significant differences favoring the Centurion.
Conclusions: Compared to the Infiniti with IP mode, cataract
surgery with the Centurion without IP mode is likely to be
performed with less phacoemulsification energy and higher
efficiency.},

   abstract = {BACKGROUND/AIMS: VEGF-A is induced by oxidative stress, and functions as a survival factor for various cell types, including retinal pigment epithelial (RPE) cells. Anti-vascular endothelial growth factor (VEGF) drugs like aflibercept and bevacizumab have shown to be most effective in treating neovascular age-related macular degeneration (AMD), however uptake of the drugs might lead to interference with cell physiology. Herein, we evaluated the significance of the Fc receptor (FcR) within this context and moreover explored the impact of VEGF inhibition under normal conditions as well as under oxidative stress, in terms of potential adverse effects. METHODS: ARPE-19 (human RPE) cells were treated with aflibercept and bevacizumab in presence or absence of H2O2 as oxidative stress stimulus. After 24h cells were evaluated for drug uptake, VEGF-A expression and secretion, levels of intracellular reactive oxygen species (ROS) as well as cell proliferation. Experiments were repeated with cells being pre-incubated with an FcR inhibitor prior to drug application. RESULTS: Both drugs inhibited extracellular levels of VEGF-A and were taken up into the RPE, resulting in significantly reduced intracellular levels of VEGF-A. When oxidative stress was applied, intracellular ROS levels in cells treated with both drugs rose, and cell proliferation was reduced. Prior incubation with the FcR inhibitor lessened the uptake of bevacizumab, but not aflibercept into RPE cells, and simultaneously enhanced cell survival under oxidative stress conditions. CONCLUSIONS: Our results indicate that uptake and accumulation of aflibercept and bevacizumab within RPE cells affect the intracellular VEGF-A metabolism negatively, leading to a biologically relevant reduced cell survival under oxidative stress. The FcR plays a substantial role in the uptake of bevacizumab, but not aflibercept, which allows an enhanced RPE cell survival through FcR blockage in an environment dominated by oxidative stress, as clinically significant for various inflammatory retinal disorders.},

   abstract = {Vascular endothelial growth factor (VEGF) secreted by the retinal pigment epithelium (RPE) plays an important role in ocular homeostasis, but also in diseases, most notably age-related macular degeneration (AMD). To date, anti-VEGF drugs like ranibizumab have been shown to be most effective in treating these pathologic conditions. However, clinical trials suggest that the RPE could degenerate and perish through anti-VEGF treatment. Herein, we evaluated possible pathways and outcomes of the interaction between ranibizumab and human RPE cells (ARPE-19). Results indicate that ranibizumab affects the VEGF-A metabolism in RPE cells from an extra- as well as intracellular site. The drug is taken up into the cells, with the VEGF receptor 2 (VEGFR-2) being involved, and decreases VEGF-A protein levels within the cells as well as extracellularly. Oxidative stress plays a key role in various inflammatory disorders of the eye. Our results suggest that oxidative stress inhibits RPE cell proliferation. This anti-proliferative effect on RPE cells is significantly enhanced through ranibizumab, which does not inhibit RPE cell proliferation substantially in absence of relevant oxidative stress. Therefore, we emphasize that anti-VEGF treatment should be selected carefully in AMD patients with preexistent extensive RPE atrophy.},

   abstract = {Recently introduced new technologies that enable temperature-controlled laser irradiation on the RPE allowed us to investigate temperature-resolved RPE cell responses. In this study we aimed primarily to establish an experimental setup that can realize laser irradiation on RPE cell culture with the similar temperature distribution as in the clinical application, with a precise time/temperature history. With this setup, we conducted investigations to elucidate the temperature-dependent RPE cell biochemical responses and the effect of transient hyperthermia on the responses of RPE cells to the secondary-exposed oxidative stress. Porcine RPE cells cultivated in a culture dish (inner diameter = 30 mm) with culture medium were used, on which laser radiation (lambda = 1940 nm, spot diameter = 30 mm) over 10 s was applied as a heat source. The irradiation provides a radially decreasing temperature profile which is close to a Gaussian shape with the highest temperature in the center. Power setting for irradiation was determined such that the peak temperature (Tmax) in the center of the laser spot at the cells reaches from 40 degrees C to 58 degrees C (40, 43, 46, 50, 58 degrees C). Cell viability was investigated with ethidium homodimer III staining at the time points of 3 and 24 h following laser irradiation. Twenty four hours after laser irradiation the cells were exposed to hydrogen peroxide (H2O2) for 5 h, followed by the measurement of intracellular glutathione, intracellular 4-hydroxynonenal (HNE) protein adducts, and secreted vascular endothelial growth factor (VEGF). The mean temperature threshold for RPE cell death after 3 h was found to be around 52 degrees C, and for 24 h around 50 degrees C with the current irradiation setting. A sub-lethal preconditioning on Tmax = 43 degrees C significantly induced the reduced glutathione (GSH)/oxidized glutathione (GSSG) ratio, and decreased H2O2-induced increase of intracellular 4-HNE protein adducts. Although sub-lethal hyperthermia (Tmax = 40 degrees C, 43 degrees C, and 46 degrees C) caused a slight increase of VEGF secretion in 6 h directly following irradiation, secondary exposed H2O2-induced VEGF secretion was significantly reduced in the sub-lethally preheated groups, where the largest effect was seen following the irradiation with Tmax = 43 degrees C. In summary, the current results suggest that sub-lethal thermal laser irradiation on the RPE at Tmax = 43 degrees C for 10 s enhances cell defense system against oxidative stress, with increasing the GSH/GSSG ratio. Together with the results that the decreased amount of H2O2-induced 4-HNE in sub-lethally preheated RPE cells was accompanied by the lower secretion of VEGF, it is also strongly suggested that the sub-lethal hyperthermia may modify RPE cell functionality to protect RPE cells from oxidative stress and associated functional decrease, which are considered to play a significant role in the pathogenesis of age-related macular degeneration and other chorioretinal degenerative diseases.},

   abstract     = {PURPOSE: To correlate the long-term clinical effect of photocoagulation lesions after 6 months, as measured by their retinal damage size, to exposure parameters. We used optical coherence tomographic (OCT)-based lesion classes in order to detect and assess clinically invisible and mild lesions. METHODS: In this prospective study, 488 photocoagulation lesions were imaged in 20 patients. We varied irradiation diameters (100/300 microm), exposure-times (20-200 ms), and power. Intensities were classified in OCT images after one hour, and we evaluated OCT and infrared (IR) images over six months after exposure. RESULTS: For six consecutive OCT-based lesion classes, the following parameters increased with the class: ophthalmoscopic, OCT and IR visibility rate, fundus and OCT diameter, and IR area, but not irradiation power. OCT diameters correlated with exposure-time, irradiation diameter, and OCT class. OCT classes discriminated the largest bandwidth of OCT diameters. CONCLUSION: OCT classes represent objective and valid endpoints of photocoagulation intensity even for "subthreshold" intensities. They are suitable to calculate the treated retinal area. As the area is critical for treatment efficacy, OCT classes are useful to define treatment intensity, calculate necessary lesion numbers, and universally categorize lesions in clinical studies.},

   abstract = {PURPOSE: To investigate the effects of Bruch's membrane (BrM) neutral lipid deposition in mouse models and its significance to aging and age-related macular degeneration, it is essential to reliably detect small quantities of neutral lipids including esterified cholesterol (EC). In chorioretinal sections and BrM wholemounts, we tested a novel fluorescent cholesterol marker based on the bacterial toxin perfringolysin O (PFO) and compared results with those obtained with the classic cholesterol dye filipin. METHODS: An engineered plasmid containing the specific cholesterol binding domain (D4) of PFO fused to green fluorescent protein (GFP) was expressed in cultured E. coli, isolated, purified, and concentrated. A total of 150 BrM-choroid wholemounts and chorioretinal sections of 11- to 13-month-old ApoE(null) mice were prepared and stained with PFO/D4-GFP or filipin for EC. Samples were examined by epifluorescence microscopy. RESULTS: The fluorescence intensity of PFO/D4-GFP was strong, stable, and, if small quantities of EC were present, superior to filipin. In all specimens, we could sharply locate the PFO/D4-GFP signal to BrM. A semiquantitative evaluation of BrM lipid deposition is possible by measuring PFO/D4-GFP fluorescence intensity. CONCLUSIONS: The use of PFO/D4-GFP allowed a robust and direct detection of EC in aged murine BrM. In wholemount samples, its strong and stable fluorescence facilitated a semiquantitative evaluation of BrM-EC content over a large area. The patterns of EC deposition in murine BrM wholemounts are comparable with findings in human BrM wholemounts. Perfringolysin O/D4-GFP could be an important tool for investigating the effects of BrM lipid deposition in mouse models.},

   abstract = {PurposeSublethal thermal therapy of the retinal pigment epithelium (RPE) is discussed as a new prophylactic therapy for age-related macular degeneration. However, temperature-dependent RPE cell effects have not been well elucidated. We investigated the biochemical responses of RPE cells following sublethal to lethal thermal laser irradiation. MethodsPorcine RPE cells cultured in a dish (33mm) were heated with a Thulium laser (1.92{micro}m, 1-20W, 10s) over a spot of 3mm. Temperatures during irradiation were measured with thermocouples. Cell viability was examined using annexin-V, ethidium homodimer III and Hoechst 33342 for detecting apoptotic, necrotic and living cell, respectively, by using fluorescence microscopy for localization and flow cytometry for quantification. Secretion of vascular endothelial growth factor (VEGF) for 6h following irradiation on different temperatures was assessed with Elisa assay. In order to examine a protective effect of sublethal hyperthremia, the cells were heated up to 45C 24h prior to the exposure of 2 mM hydroxyl peroxide (H2O2) for 5 h. The involvement of TRPV (Transient Receptor Potential Vanilloid)-1 receptor, which is activated with temperatures > 43C, was investigated by adding capsazepin, a TRPV-1 inhibitor, before irradiation. ResultsCell apoptosis and necrosis was observed 24 h after irradiation with a central peak temperature [&ge;]52C. Fluorescence microscopy revealed apoptotic cells around the central necrotic area. VEGF secretion for 6h after irradiation was significantly increased at peak temperatures between 40 and 52C in a temperature dependent manner (max. 110%, p<0.05), whereas the total secretion decreases with temperatures > 52C. Pre-irradiation onto 45C significantly reduced H2O2-induced cell death after 5h compared to non-heated cells (total cell death: 15.6% to 10.2%, necrosis: 6% to 4 %, early apoptosis: 5.1% to 3.6%; p<0.01). These effects were not observed in the existence of capsazepin during laser irradiation. ConclusionsThe number of apoptotic and necrotic RPE cells increase at least over 24h following thermal laser irradiation. Sublethal temperatures between 40 and 52C seem to induce various cellular responses as VEGF secretion, which might be related to the protective effect against oxidative stress. Results with capsazepin suggest that TRPV-1 channel activation by hyperthermia is essential to exert this protective effect.},

   abstract = {PURPOSE: The aim of this study was to investigate the autofluorescence (AF) of the RPE with two-photon microscopy (TPM) and fluorescence lifetime imaging (FLIM) under normal and oxidative stress conditions. METHODS: Porcine RPE-choroid explants were used for investigation. The RPE-choroid tissue was preserved in a perfusion organ culture system. Oxidative stress was induced by laser photocoagulation with frequency-doubled Nd:YAG laser (532 nm) and by exposure to different concentrations (0, 1, 10 mM) of ferrous sulfate (FeSO4) for 1 hr. At indicated time points after exposure, the tissue was examined with TPM and FLIM. Intracellular reactive oxygen species around the photocoagulation lesion were detected with chloromethyl-2'7'-dichlorofluorescein diacetate (CM-H2DCFDA). Melanosomes were isolated from RPE cells and its fluorescence properties were investigated under normal and oxidized conditions. RESULTS: Under normal condition, AF in RPE cells with TPM is mostly originated from melanosomes, which has a very short fluorescence lifetime (FLT) (mean=117 ps). Under oxidative stress induced by laser irradiation and FeSO4 exposure, bright granular AF appears inside and around RPE cells, whose FLT is significantly longer (mean=1388 ps) than the FLT of the melanosome-AF. Excitation and emission peaks are found at 710-750 nm and 450-500 nm, respectively. Oxidative stress increases the fluorescence intensity of the melanosomes but does not change their FLT. CONCLUSION: TPM reveals acute oxidative stress-induced bright AF granules inside and around RPE cells which can be clearly discriminated from melanosomes by FLIM. TPM combined with FLIM is a useful tool of live-cell analysis to investigate functional alterations of the RPE.},

   abstract = {The purpose of this study was to investigate release of matrix metalloproteinases (MMP) 2 and 9 during retinal pigment epithelium (RPE) wound healing after Selective Retina Therapy (SRT) with laser energy levels below and above the threshold of RPE cell death. Following exposure to SRT using a prototype pulsed Nd:YLF laser with energies of 80-180 mJ/cm(2) fresh porcine RPE-monolayers with Bruch's membrane and choroid were cultured in modified Ussing chambers which separate the apical (RPE-facing) and basal (choroid facing) sides of the RPE monolayer. Threshold energy for RPE cell death and wound healing were determined with calcein-AM viability test. Inactive and active forms of MMP 2 and 9 were quantified within tissue samples and in the culture medium of the apical and basal compartments of the Ussing chamber using gelatine zymography. Laser energies of 160-180 mJ/cm(2) resulted in cell death within 1 h while 120-140 mJ/cm(2) resulted in delayed death of exposed RPE cells. All cells survived 80 and 100 mJ/cm(2). Laser spots healed within 6 days after SRT accompanied by a transient vectorial increase of MMPs. SRT with 180 mJ/cm(2) increased active MMP 2 by 1.9 (p < 0.05) and 1.6 (p < 0.05) fold in tissue and basal compartments, respectively, without alterations in the apical compartment. Pro-MMP 2 levels were also significantly increased in all compartments (p < 0.05). Release of MMP 9 was not altered. Laser energy below the threshold of RPE cell death did not alter the release of MMP 2 or 9. The findings suggest that the release of active MMP 2 on the basal side of the RPE during wound healing following SRT may address age-related pathological changes of Bruch's membrane with a potential to slow degenerative macular ageing processes before irreversible functional loss has occurred.},

   abstract = {Purpose. Retinal laser photocoagulation carries the risk of overtreatment due to effect variation of identically applied lesions. The degree of coagulation depends on the induced temperature increase and on exposure time. We introduce temperature controlled photocoagulation (TCP), which uses optoacoustics to determine individually exposure times necessary to create reproducible lesions. Methods. Optoacoustic temperature measurement relies on pressure waves that are excited in the retinal tissue by repetitive low-energy laser pulses. Signal amplitudes correlate with tissue temperature and are detected by a transducer in the laser contact lens. We used a continuous wave (CW) photocoagulator for treatment irradiation and superimposed probe laser pulses for simultaneous temperature measurement. Optoacoustic data of 1500 lesions (rabbit) were evaluated to develop an algorithm that controls exposure times automatically in TCP. Lesion diameters of 156 TCP lesions were compared to 156 non-controlled lesions. Histology was performed after 1 hour, and 1 and 4 weeks. Results. TCP resulted in exposure times from 4 to 800 ms depending on laser power chosen. Ophthalmoscopic and histologic lesion diameters were independent of power between 14 and 200 mW. TCP lesions barely were visible with a mean diameter equal to the treatment beam (130 mum). In contrast, standard lesion diameters increased linearly and statistically significantly with power. Histology confirmed sparing of the ganglion and nerve fiber layers in TCP. Conclusions. TCP facilitates uniform retinal lesions over a wide power range. In a clinical setting, it should generate soft and reproducible lesions independently of local tissue variation and improve safety, particularly at short exposure times.},

   abstract = {PurposeTo investigate temperature increase-induced secretion of vascular endothelial growth factor (VEGF) from retinal pigment epithelial (RPE) cells and its contribution to adoptive response relating to cell defence system against oxidative stress. MethodsPorcine RPE cells on 35 mm culture dish were used in the study. Thulium laser ({lambda}=1940 nm, spot size 33 mm was utilized as a heat source. Temperature increase during irradiation for different power and time setting at cell level was measured with thermocouple, and power and time setting of the experiment was determined based on this calibration. Culture medium was replaced by 1.2 ml phosphate buffer saline and then laser was irradiated with different power settings for 10 seconds, so that the peak temperature reaches from 40{degrees}C to 65{degrees}C. Cellular viability after laser irradiation was examined with MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay immediately after irradiation. VEGF secretion was investigated with enzyme-linked immunosorbent assay (ELISA) at 2 and 24 hrs after irradiation. Contribution of a temperature-dependent calcium channel, TRPV (transient receptor potential vanilloid) channels in laser-induced VEGF secretion was investigated using TRPV channel blocker, ruthenium red (20 {micro}M). TRPV channel blocker-containing medium was replaced by the normal medium soon after laser irradiation. Hydrogen peroxide (H2O2) or advanced glycation endproduct (AGE)-was exposed after 6 hrs of laser irradiation and cell viability was examined with MTT assay. ResultsPeak temperature threshold for immediate RPE cell death was found around 55 {degrees}C with our irradiation setting. VEGF secretion was increased after sub-lethal irradiation in power-dependent manner, which was partially suppressed by TRPV channel blocker. Sublethal laser irradiation reduced H2O2 and AGE-induced cell death and this effect was smaller in the cells treated with TRPV channel inhibitor during laser irradiation. ConclusionsSublethal temperature increase-induced VEGF production might contribute to the enhancement of RPE cell defence system against oxidative stress.},

In order to obtain useful information from study results, choosing the suitable experimental model for each purpose of study is of great importance. Although RPE cell cultures are widely used, cells in cell culture have significantly different phenotypical characteristics from in vivo cells. The advantage of using native tissue is that cells in the tissue have close biological properties to in vivo conditions. This review describes basic characteristics of native RPE–choroid tissues in comparison to RPE cells in cell culture and introduces the possibility of preserving tissues in different culture systems. Advantages and disadvantages of organ culture and suitable studies with recent study results are also introduced.},

METHODS: PorcineRPE-choroid tissue was cultivated in a perfusion tissue culture system. After the indicated times, histology, immunolocalization of collagen IV and von Willebrand factor, RPE cell viability with calcein-AM, TUNEL assay and occludin immunolocalization of RPE cells were examined. The tissue was treated with selective RPE treatment laser after different time periods and the wound healing response was characterized. Vascular endothelial growth factor secretion was measured by enzyme-linked immunosorbent assay. RESULTS: On day 8, prominent morphological degenerative changes of RPE cells were observed in histology. According to the immunohistochemistry for collagen IV, the Bruch's membrane did not display any obvious decomposition until day 8. Von Willebrand factor staining decreased during cultivation, especially at the choriocapillaris. Calcein-AM staining and TUNEL assay displayed the increase of apoptotic changes in only a minority of the cells on day 4, but in many cells on day 8. Occludin delocalization was observed on day 8. Selective RPE treatment laser-produced wounds were completely closed by monolayer RPE when wounded on fresh and 3-day-old cultures, but not when wounded on 6-day-old cultures. Vascular endothelial growth factor secretion was stable between days 2 and 5, but increased after that. CONCLUSION: Under the stated culture perfusion conditions, porcine RPE-choroid tissue was suitable for experimentation up to 5 days of maintenance.},

   abstract = {PURPOSE: To investigate the influence of VEGF antagonists on the barrier function of the retinal pigment epithelium and underlying mechanisms. METHODS: Porcine RPE cells were cultured on six-well membrane inserts. The cells were exposed to bevacizumab (62.5 microg/mL) or ranibizumab (25 microg/mL) for 24 hours (short term) or 9 days (long term). Transepithelial flux of FITC-dextran and intracellular levels of reduced glutathione (GSH) at normal and low-glucose conditions were investigated at different points in time. The influence of the addition of triamcinolone acetonide (TA) was investigated. The effect of GSH depletion on RPE permeability was examined using L-buthionine sulfoximine (BSO), a gamma-glutamylcysteine synthethase inhibitor. RESULTS: After short-term exposure, VEGF antagonists increased the transepithelial flux of FITC-dextran significantly on day 2. Bevacizumab, but not ranibizumab, increased permeability up to 9 days. Under long-term exposure, both drugs enhanced permeability for 7 days; bevacizumab had the stronger effect. The addition of TA inhibited this increase. At the ninth day of short- and long-term exposure, bevacizumab-exposed cells, but not ranibizumab-exposed cells, exhibited a significantly lower GSH level. In the low-glucose condition, both drugs accelerated the decrease of intracellular GSH for the first 48 hours. GSH depletion increased the permeability of retinal pigment epithelium. TA had no effect on BSO-induced GSH depletion. CONCLUSIONS: The results suggest that bevacizumab and ranibizumab may decrease RPE barrier function, with bevacizumab exhibiting a prolonged and more profound effect. Combination with TA is thought to be beneficial because of its protective effect on stabilizing RPE junctional integrity.},

   abstract = {PURPOSE: Oxidative stress is known to disrupt the integrity of retinal pigment epithelium (RPE) tight junctions. The goal of this study is to evaluate the effect of triamcinolone acetonide (TA) on the junctional integrity of RPE under oxidative stress and to identify the underlying mechanisms. METHODS: Second passage porcine RPE cells were cultured on 6-well membrane inserts until 4 weeks after reaching confluence. Cells were incubated with TA (10(-5) M) for 30 min. FITC-containing medium was added to the upper chamber (cell's apical side). The cells were then challenged with 1 mM Hydrogen Peroxide (H(2)O(2)). After 5 h, the fluorescence intensity of the medium from lower chamber (cell's basolateral side) was measured using a fluorescence spectrofluorophotometer. This transepithelial flux of FITC-dextran was measured until the 21st day. The immunolocalization of occludin and F-actin was examined with fluorescence microscope. Reduced glutathione (GSH)/oxidized glutathione (GSSG) ratio was determined by a colorimetric assay kit. RESULTS: Non-lethal oxidative stress by H(2)O(2) increased transepithelial flux of FITC-dextran significantly. TA inhibited this increase and preserved the lower flux through the whole experimental period. This permeability change by H(2)O(2) was reversible and recovered to the normal level within 3 weeks. In immunohistological study, H(2)O(2) reduced linear occludin staining at the cell border and increased actin stress fibers. TA prevented H(2)O(2)-induced disruption of junctional assembly of occludin and F-actin. Glutathione assay demonstrated that intracellular GSH/GSSG ratio decreased significantly with H(2)O(2), while TA preserved this ratio by up-regulating GSH synthesis. CONCLUSIONS: TA has a protective effect against oxidative stress-induced disruption of RPE tight junction by preserving cellular redox state.},

   abstract = {PURPOSE: A defect in retinal pigment epithelial (RPE) cells may cause dysfunction of the neural retina, so rapid recovery of differentiated RPE cells is required after RPE injury. We investigated the effect of hepatocyte growth factor (HGF) on wound healing in RPE cells. METHODS: Confluent monolayers of bovine RPE cells were denuded, and the cells were allowed to recover in the presence or absence of HGF. The effect of HGF on RPE cell proliferation was evaluated by a 3-(4;5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulphophenyl)-2H-tet raz olium assay. In a migration assay, mitomycin C was used to inhibit proliferation, and the number of migrated cells was counted. The signaling pathways involved were examined using inhibitors of mitogen-activated protein kinase (MAPK), phosphatidylinositol-3 (PI3) kinase and protein kinase C pathways. RESULTS: At 80 ng/mL, HGF stimulated the wound closure of RPE monolayers and rendered the restituted cells more epithelioid in shape. HGF at 10 ng/mL stimulated RPE cell migration the most, whereas 80 ng/mL of HGF inhibited migration, but stimulated proliferation the most. In particular, PI3 kinase and MAPK inhibitor inhibited PRE cell migration and proliferation, respectively. CONCLUSIONS: HGF stimulated wound closure in cultured RPE cells, and rendered restituted cells epithelioid in shape. HGF may become a therapeutic candidate for RPE wound healing.},

   abstract = {BACKGROUND: Although hepatocyte growth factor (HGF) is also known as scatter factor, it induces epithelial morphogenesis in cultured bovine retinal pigment epithelial (RPE) cells. To elucidate the mechanism of epithelial morphogenesis, we investigated the influence of HGF on occludin, a major component of tight junctions. METHODS: RPE cells were plated on collagen type 1-coated chamber slides or dishes, 20 ng/ml HGF was added and the cells were incubated for 1 week. Cells were harvested at several time-points, and occludin expression was examined by immunohistochemistry. Detergent extraction protocols to identify the intensity of occludin linkage to the cytoskeleton were also used. Occludin expression was determined semiquantitatively by Western blotting. RESULTS: Fluorescence microscopy revealed that HGF treatment increased the levels of insoluble occludin at the cell borders after detergent extraction. These level of insoluble occludin and the associated epithelial morphology were maintained for more than 3 weeks after withdrawal of HGF, whereas cells not treated with HGF had a fibroblastic appearance. Western blotting also showed that insoluble occludin was more abundant in HGF-treated cells. Furthermore, immunoreactive bands of insoluble occludin were somewhat larger than those of soluble occludin, suggesting that insoluble occludin may be modified in comparison to soluble occludin. CONCLUSION: Our results suggest that HGF promotes linkage of occludin to the cytoskeleton. HGF may become a therapeutic candidate in physiological recovery of RPE cells and in preparation of RPE monolayers for transplantation.},

   abstract = {Removal of epiretinal membrane of the macula was performed in 49 eyes of 48 consecutive patients, and visual prognosis was analyzed retrospectively. Best-corrected visual acuity improved in 32 eyes (65%), and was unchanged in 17 eyes (35%). Metamorphopsia improved in 27 eyes (60%), and was unchanged in 18 eyes (40%). Eyes having proliferative tissue on the retinal surface after removal of epiretinal membrane showed significantly poorer improvement of metamorphopsia than those having a smooth retinal surface. However, duration of visual disturbance before surgery and preoperative visual acuity were not associated with the outcome of the metamorphopsia. Intentional peeling of the internal-limiting membrane was performed after removal of the epiretinal membrane in 17 of 40 eyes with idiopathic epiretinal membrane, and the effect of this procedure on improvement of metamorphopsia was evaluated. Internal-limiting membrane peeling did not influence the rate of improvement of metamorphopsia, however, its efficacy and safety remain to be determined in larger case series. (author abst.)},
