abstract = {Accurate assessment of corneal curvatures using frequency domain optical coherence tomography (OCT) with galvanometer scanners remains challenging due to the well-known scan field distortion. This paper presents an algorithm and software for correcting the distortion using only two simple measurements in which a readily available standard sphere is positioned in different depths in front of the OCT scanner. This offers a highly accessible and easily reproducible method for the field distortion correction (FDC). The correction was validated by measuring different spherical phantoms and conducting corneal curvature measurements of ex vivo porcine corneas using a commercial spectral-domain OCT system and a clinically approved swept-source OCT as a reference instrument. Thus, the error in radius measurements of spherical phantoms was reduced by \>90\% and astigmatism by \>80\% using FDC. In explanted porcine eyes, the error in astigmatism measurements with the Telesto was reduced by 75\% for power and 70\% for angle. The best fitting sphere radius was determined up to a deviation of 0.4\% from the Anterion. This paper describes a correction algorithm for OCT immanent distortion that is applicable to any scanning OCT setup and enables precise corneal curvature measurements. The MATLAB software for the FDC is publicly available on GitHub.},

abstract = {Two-Photon Microscopy (TPM) can provide three-dimensional morphological and functional contrast in vivo. Through proper staining, TPM can be utilized to create virtual, HE equivalent images and thus can improve throughput in histology-based applications. We previously reported on a new light source for TPM that employs a compact and robust fiber-amplified, directly modulated laser. This laser is pulse-to-pulse wavelength switchable between 1064 nm, 1122 nm, and 1186 nm with an adjustable pulse duration from 50ps to 5ns and arbitrary repetition rates up to 1MHz at kW-peak powers. Despite the longer pulse duration, it can achieve similar average signal levels compared to fs-setups by lowering the repetition rate to achieve similar cw and peak power levels. The longer pulses lead to a larger number of photons per pulse, which yields single shot fluorescence lifetime measurements (FLIM) by applying a fast 4 GSamples/s digitizer. In the previous setup, the wavelengths were limited to 1064 nm and longer. Here, we use four wave mixing in a non-linear photonic crystal fiber to expand the wavelength range down to 940 nm. This wavelength is highly suitable for imaging green fluorescent proteins in neurosciences and stains such as acridine orange (AO), eosin yellow (EY) and sulforhodamine 101 (SR101) used for histology applications. In a more compact setup, we also show virtual HE histological imaging using a direct 1030 nm fiber MOPA.},

   abstract = {The selective inhibition of intracellular and nuclear molecules such as Ki-67 holds great promise for the treatment of cancer and other diseases. However, the choice of the target protein and the intracellular delivery of the functional agent remain crucial challenges. Main hurdles are (a) an effective delivery into cells, (b) endosomal escape of the delivered agents, and (c) an effective, externally triggered destruction of cells. Here we show a light-controlled two-step approach for selective cellular delivery and cell elimination of proliferating cells. Three different cell-penetrating nano constructs, including liposomes, conjugates with the nuclear localization sequence (NLS), and conjugates with the cell penetrating peptide Pep-1, delivered the light activatable antibody conjugate TuBB-9-FITC, which targets the proliferation associated protein Ki-67. HeLa cells were treated with the photosensitizer benzoporphyrin monoacid derivative (BPD) and the antibody constructs. In the first optically controlled step, activation of BPD at 690 nm triggered a controlled endosomal escape of the TuBB-9-FITC constructs. In more than 75% of Ki-67 positive, irradiated cells TuBB-9-FITC antibodies relocated within 24 h from cytoplasmic organelles to the cell nucleus and bound to Ki-67. After a second light irradiation at 490 nm, which activated FITC, cell viability decreased to approximately 13%. Our study shows an effective targeting strategy, which uses light-controlled endosomal escape and the light inactivation of Ki-67 for cell elimination. The fact that liposomal or peptide-assisted delivery give similar results leads to the additional conclusion that an effective mechanism for endosomal escape leaves greater variability for the choice of the delivery agent.},

   abstract = {Retinal photocoagulation is an established treatment for various retinal diseases. The temperature development during a treatment can be monitored by applying short laser pulses in addition to the treatment laser light. The laser pulses induce thermoelastic pressure waves that can be detected at the cornea. We present a numerical model to examine the temperature development during the treatment as well as the formation and propagation of the ultrasonic waves. Using the model, it is possible to determine the peak temperature during retinal photocoagulation from the measured signal, and investigate the behaviour of the temperature profile and the accuracy of the temperature determination under varying conditions such as inhomogeneous pigmentation or change in irradiation parameters. It was shown that there is an uncertainty of 2.5 -9% in the determination of the peak temperature when the absorption coefficient between the absorbing layers is varied by a factor of 2. Furthermore the model was extended in order to incorporate the photoacoustic pressure generation and wave propagation. It was shown that for an irradiation pulse duration of 75 ns the resulting pressure wave energy is attenuated by 76 % due to frequency dependent attenuation in water.},

   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 = {The scientific background of laser photocoagulation of the ocular fundus was studied extensively by several investigators in the 1970 s and 1980 s. The basic principles were succesfully resolved during that time and clinical consequences for proper application of the laser photocoagulation for various diseases were deduced. The present paper gives an overview about the physical basics of laser-tissue interactions during and after retinal laser treatment and the particular laser strategies in the treatment of different retinal diseases. Thus, it addresses the issue of the impact on tissue of laser parameters as wavelength, spot size, pulse duration and laser power. Additionally, the different biological tissue reactions after laser treatment are presented, such as, e.g., for retinopexia or macular treatments as well as for diabetic retinopathies. Specific laser strategies such as the selective laser treatment of the RPE (SRT) or the transpupillary thermotherapy (TTT) are presented and discussed.},

   abstract = {PURPOSE: To determine if photodynamic therapy with verteporfin (Visudyne; Novartis AG, Bulach, Switzerland), termed verteporfin therapy, can safely reduce the risk of vision loss compared with a placebo (with sham treatment) in patients with subfoveal choroidal neovascularization caused by age-related macular degeneration who were identified with a lesion composed of occult with no classic choroidal neovascularization, or with presumed early onset classic choroidal neovascularization with good visual acuity letter score,
METHODS: This was a double-masked, placebo controlled (sham treatment), randomized, multicenter clinical trial involving 28 ophthalmology practices in Europe and North America. The study population was patients with age related macular degeneration, with subfoveal choroidal neovascularization lesions measuring no greater than 5400 mum in greatest linear dimension with either 1) occult with no classic choroidal neovascularization, best-corrected visual acuity score of at least 50 (Snellen equivalent approximately 20/100), and evidence of hemorrhage or recent disease progression; or 2) evidence of classic choroidal neovascularization with a best-corrected visual acuity score of at least 70 (better than a Snellen equivalent of approximately 20/40); assigned randomly (2:1) to verteporfin therapy or placebo therapy. Verteporfin (6 mg per square meter of body surface area) or placebo (5% dextrose in water) was administered by means of intravenous infusion of 30 mi over 10 minutes. Fifteen minutes after the start of the infusion, a laser light at 689 nm delivered 50 J/cm(2) by application of an intensity of 600 mW/cm(2) over 83 seconds using a spot size with a diameter 1000 mum larger than the greatest linear dimension of the choroidal neovascularization lesion on the retina. At follow-up examinations every 3 months, retreatment with the same regimen was applied if angiography showed fluorescein leakage. The main outcome measure was at least moderate vision loss, that is, a loss of at least 15 letters (approximately 3 lines), adhering to an intent-to treat analysis with the last observation carried forward to impute for missing data.
RESULTS: Two hundred ten (93%) and 193 (86%) of the 225 patients in the verteporfin group compared with 104 (91%) and 99 (87%) of the 114 patients in the placebo group completed the month 12 and 24 examinations, respectively. On average, verteporfin-treated patients received five treatments over the 24 months of follow-up. The primary outcome was similar for the verteporfin-treated and the placebo-treated eyes through the month 12 examination, although a number of secondary visual and angiographic outcomes significantly favored the verteporfin-treated group. Between the month 12 and 24 examinations, the treatment benefit grew so that by the month 24 examination, the vertepor-fin-treated eyes were less likely to have moderate or severe vision loss. Of the 225 verteporfin-treated patients, 121 (54%) compared with 76 (67%) of 114 placebo-treated patients lost at least 15 letters (P =.023). Likewise, 61 of the verteporfin-treated patients (30%) compared with 54 of the placebo-treated patients (47%) lost at least 30 letters (P = .001). Statistically significant results favoring verteporfin therapy at the month 24 examination were consistent between the total population and the subgroup of patients with a baseline lesion composition identified as occult choroidal neovascularization with no classic choroidal neovascularization, This subgroup included 166 of the 225 verteporfin-treated patients (74%) and 92 of the 114 placebo-treated patients (81%). In these patients, 91 of the verteporfin-treated group (55%) compared with 63 of the placebo-treated group (68%) lost at least 15 letters (P =.032), whereas 48 of the verteporfin-treated group (29%) and 43 of the placebo-treated group (47%) lost at least 30 letters (P =.004). Other secondary outcomes, including visual acuity letter score worse than 34 (approximate Snellen equivalent of 20/200 or worse), mean change in visual acuity letter score, development of classic choroidal neovascularization, progression of classic choroidal neovascularization and size of lesion, favored the verteporfin-treated group at both the month 12 and month 24 examination for both the entire study group and the subgroup of cases with occult with no classic choroidal neovascularization at baseline. Subgroup analyses of lesions composed of occult with no classic choroidal neovascularization at baseline suggested that the treatment benefit was greater for patients with either smaller lesions (4 disc areas or less) or lower levels of visual acuity (letter score less than 65, an approximate Snellen equivalent of 20/50(-1) or worse) at baseline. Prospectively planned multivariable analyses confirmed that these two baseline variables affected the magnitude of treatment benefit. Of the 123 verteporfin-treated patients and 64 placebo-heated patients with either visual acuity score Less than 65 or lesion size 4 disc areas or less at baseline, 60 (49%) and 48 (75%) lost at least 15 letters (P < .001), respectively, and 26 (21%) and 31 (48%) lost at least 30 letters (P <.001), respectively, at the month 24 examination. Conversely, treatment may not be beneficial for patients with both larger lesions and good visual acuity (both greater than 4 disc areas and letter score 65 or greater, an approximate Snellen equivalent of 20/50 or better). With respect to safety for the entire study group, 10 of 225 verteportin-treated patients (4.
4%) and none of the placebo-treated patients had a severe decrease of vision (at least 20 letters compared with the visual acuity just before the treatment) within 7 days after treatment, judged to be the result of the development of subretinal pigment epithelial blood, marked subretinal fluid associated with choroidal hypofluorescence, or no obvious cause. Five of these 10 patients had recovery of vision to less than a 20-letter loss compared with the pretreatment vision score at 3 months after this event. Photosensitivity reactions occurred in only one patient in each group.
CONCLUSIONS: In this trial of patients with agerelated macular degeneration and subfoveal choroidal neovascularisation lesions composed of occult with no classic choroidal neovascularization, verteporfin therapy significantly reduced the risk of moderate and severe visual acuity loss. Subgroup analyses suggest that a greater benefit was achieved in patients presenting with either smaller lesions (4 disc areas or less) or lower levels of visual acuity (letter score less than 65, an approximate Snellen equivalent of 20/50(-1) or less). The Verteporfin In Photodynamic Therapy Study Group recommends that this therapy should be considered for the treatment of patients with age-related macular degeneration with subfoveal lesions composed of occult with no classic choroidal neovascularization who are presumed to have recent disease progression. Patients to be treated should be aware of a small (4%) risk of acute, severe vision decrease.<(c)> 2001 by Elsevier Science Inc. All rights reserved.).},

   abstract = {PURPOSE. To evaluate a new angiographic technique that offers three-dimensional imaging of chorioretinal vascular diseases.
METHODS. Fluorescein (FA) and indocyanine green angiography (ICGA) were performed using. a confocal scanning laser ophthalmoscope. Tomographic series with 32 images per set were taken over a depth of 4 min at an image frequency of 20 Hz. An axial analysis was performed for each x/y position to determine the fluorescence distribution along, the z-axis. The location of the onset of fluorescence at a defined threshold intensity was identified and a depth profile was generated. The overall results of fluorescence topography were displayed in a gray scale-coded image and three-dimensional relief.
RESULTS. Topographic angiography delineated the choriocapillary surface covering.. the posterior pole with exposed larger retinal vessels. Superficial masking of fluorescence by hemorrhage or absorbing fluid did not preclude detection of underlying diseases. Choroidal neovascularization (CNV) appeared as a vascular formation with distinct configuration and prominence. Chorioretinal infiltrates exhibited perfusion defects with dye pooling. Retinal pigment epithelium detachments (PEDs) demonstrated dynamic filling mechanisms. Intraretinal extravasation in retinal vascular disease was, detected within a well-demarcated area with prominent retinal thickening.
CONCLUSIONS. Confocal topographic angiography allows high-resolution three-dimensional imaging, of chorioretinal vascular and exudative diseases. Structural vascular changes (e.g., proliferation) are detected in respect to location and size. Dynamic processes (e.g., perfusion defects, extravasation, and barrier dysfunction) are clearly identified and may be quantified. Topographic angiography is a promising technique in the diagnosis, therapeutic evaluation, and pathophysiological evaluation of macular disease.},
