   abstract = {The extent of retinal laser coagulations depends on the temperature increase at the fundus and the time of irradiation. Due to light scattering within the eye and variable fundus pigmentation the induced temperature increase and therefore the extent of the coagulations cannot be predicted solely from the laser parameters. We use optoacoustics to monitor the temperature rise in real-time in vivo (rabbit) and ex vivo (porcine eye) and to automatically control the coagulation strength. Continuous wave treatment laser radiation and pulsed probe laser light (1-1100 ns) are coupled into the same fibre and are imaged onto the retina by a laser slit lamp. The temperature dependent pressure waves are detected by an ultrasonic transducer embedded in a customary contact lens. Below the coagulation threshold the increase in acoustic amplitude due to thermal tissue expansion is up to 40 %. Best signal to noise ratios > 10 are achieved with probe pulse durations of 1 to 75 ns. Further a time critical algorithm is developed which automatically ceases laser treatment when a certain preset coagulation strength is achieved. Coagulations with similar extent are obtained with this method in vitro and in vivo even when varying the power of the treatment laser by 50 %. These preliminary results are very promising, thus this method might be suitable for an automatic feedback controlled photocoagulation with adjustable coagulation strength.},

   abstract = {The retinal photocoagulation is an established treatment method for different retinal diseases. The extent of the thermal coagulations depends strongly on the generated temperature increase. Until now the dosage is based on a pool of experience of the treating physicians as well as the appearance of the whitish lesions on the retina. The temperature course during photocoagulation can be measured in real-time by optoacoustics. A frequency-doubled Q-switched Nd:YLF laser (523nm, 75 ns) is used for optoacoustic excitation and a continuous-wave Nd:YAG laser (532nm) with adjustable irradiation time and power for heating of the fundus tissue. The onset of coagulation is determined by a photodiode that is placed directly behind enucleated porcine eyes, which served as a model. The onset of coagulation is observed clearly when scattering sets in. The required power for coagulation increases exponentially with decreasing irradiation time. The first results on rabbit eyes in vivo indicate that the onset of coagulation defined by just barely visibile lesions at a slit lamp sets in at an ED50 threshold temperature of 63°C for an irradiation time of 400 ms. In conclusion, optoacoustics can be used to determine temperatures during retinal laser treatments in real-time. This allows evaluating the time-temperature-dependence of retinal coagulation in vivo.},

abstract = {Retinal imaging ranks amongst the most important clinical applications for optical coherence
tomography (OCT) [1, 2]. The recent demonstration of increased sensitivity [3-6] in Fourier
Domain detection [7, 8] has opened the way for dramatically higher imaging speeds, up to axial
scan rates of several tens of kilohertz. However, these imaging speeds are still not sufficient for
high density 3D datasets and a further increase to several hundreds of kilohertz is necessary. In
this paper we demonstrate a swept laser source at 1050 nm with a sweep rate of 202 kHz. The
laser source provides ~10 mW average output power, up to 60 nm total sweep range and a
sensitivity roll off of less than 10 dB over 4 mm. In vivo 2D and 3D imaging of the human retina
at a record axial scan rate of 101 kHz is demonstrated. These results suggest that swept source
OCT has the potential to significantly outperform spectral/Fourier domain OCT for ophthalmic
imaging applications in the future.},

abstract = {Phase sensitive optical coherence tomography (OCT) can be used to obtain sub-nanometer
displacement measurements of biological and non-biological samples. This technique has many
applications, including detection of small amplitude surface motion, and high axial resolution OCT
phase microscopy. Doppler OCT is another type of phase sensitive imaging, where differential
phase measurements are used to detect fluid flow in biological specimens. For all types of phase
sensitive OCT, a light source with low phase noise is required in order to provide good
displacement sensitivity. High speed imaging is also necessary in order to minimize motion artifacts
and enable the detection of fast transient events. In this manuscript, buffered Fourier Domain Mode
Locked (FDML) lasers are demonstrated for ultrahigh-speed phase sensitive OCT detection. The
lasers are operated at sweep speeds of 42, 117, and 370 kHz, and displacement sensitivities of 39,
52, and 102 pm are achieved, respectively. These displacement sensitivities are comparable to
spectrometer-based phase sensitive OCT systems, but acquisition speeds 1.4 - 13x faster are
possible using buffered FDML lasers. An additional factor of √2 improvement in noise performance
is observed for differential phase measurements, which has important implications for Doppler
OCT. Dynamic measurements of rapid, small-amplitude piezoelectric transducer motion are
demonstrated. In general, buffered FDML lasers provide excellent displacement sensitivities at
extremely high sweep speeds for phase sensitive OCT measurements.},

   abstract = {Selective Retina Treatment (SRT) is a new method to treat eye diseases associated with disorders of the RPE. Selective RPE cell damage is achieved by applying a train of 1.7 μs laser pulses at 527 nm. The treatment of retinal diseases as e.g. diabetic maculopathy (DMP), is currently investigated within clinical studies, however 200 ns pulse durations are under investigation. Transient micro bubbles in the retinal pigment epithelium (RPE) are expected to be the origin of cell damage due to irradiation with laser pulses shorter than 50 μs. The bubbles emerge at the strongly absorbing RPE melanosomes. Cell membrane disruption caused by the transient associated volume increase is expected to be the origin of the angiographically observed RPE leakage. We investigate micro bubble formation and dynamics in porcine RPE using pulse durations of 150 ns. A laser interferometry system at 830 nm with the aim of an online dosimetry control for SRT was developed. Bubble formation was detected interferometrically and by fast flash photography. A correlation to cell damage observed with a vitality stain is found. A bubble detection algorithm is presented.},

   abstract = {In most retinal laser treatments the therapeutic effect is initiated by a transient temperature increase at and around the retinal pigment epithelium (RPE). Especially in long exposure time treatments like Transpupillary Thermotherapy (TTT) choroidal perfusion has a strong influence on the realized temperature at the fundus. The fundus blood circulation and therefore the heat dissipation is influenced by the intraocular pressure (IOP), which is investigated in the study presented here. In order to reduce the choroidal perfusion, the IOP is increased by injection of physiological saline solution into the eye of anaesthetized rabbits. The fundus is irradiated with 3.64 W/cm2 by means of a TTT-laser (λ = 810 nm) for t = 20 s causing a retinal temperature increase. Realtime temperature determination at the irradiated spot is achieved by a non invasive optoacoustic technique. Perfusion can be reduced by increasing IOP, which leads to different temperature increases when irradiating the retina. This should be considered for long time laser treatments.},
