Background: A prospective evaluation of the pattern of fundus autofluorescence in cases of acute versus chronic central serous chorioretinopathy (CSR). Methods: A prospective, cross-sectional, single-centre investigation was performed using three diagnostic techniques, namely, fundus autofluorescence, optical coherence tomography and fundus fluorescein angiography to evaluate a sample of patients (n = 42 eyes) with both acute (n = 25 eyes) and chronic (n = 17 eyes) CSR. Results: Hypoautofluoresecence was found in 80 per cent (20 eyes) and 88.2 per cent (15 eyes) of eyes in the acute and chronic central serous chorioretinopathy groups, respectively, corresponding to the leakage points depicted by fluorescein angiography. Hypoautofluoresence corresponding to the areas of subretinal fluid accumulation was seen in 92 per cent (23 eyes) and 82.3 per cent (14 eyes) of the acute and chronic central serous chorioretinopathy groups, respectively. In two eyes (11.6 per cent) with chronic CSR, hyperautofluorescent changes were noted at the previous leakage points. In the acute CSR group, speckled hyperautofluorescence was detected in nine eyes (36 per cent) after the resolution of subretinal fluid. In the chronic CSR group, simultaneous speckled hyperautofluorescence was detected in the previous areas of subretinal fluid accumulation in 12 eyes (70.5 per cent). Conclusion: Fundus autofluorescence imaging delineates endogenous fluorescence derived mainly from lipofuscin within the retinal pigment epithelium (RPE) layer and therefore permits evaluation of functional alterations in the RPE in numerous retinal diseases. Data from fundus autofluorescence revealed distinctive findings in acute and chronic CSR. Fundus autofluorescence imaging may be used as a supplementary diagnostic tool for identifying patients with CSR and differentiation may be made between acute and chronic cases.

Assessment of retinal sensitivity with MP1 microperimeter is a rapid, safe and noninvasive diagnostic method. Early macular function loss in intermediate AMD can be precisely detected by MP1 microperimeter before significant visual impairment is established and it is also useful for demonstrating the shift in the localization and the stability of fixation prior to progression of intermediate AMD to advanced and exudative stage.

Aims: To assess and compare the anterior chamber depth (ACD) by different anterior segment imaging techniques. Methods: Eighty healthy eyes of 40 patients were recruited, and 3 consecutive measurements of ACD were determined prospectively utilizing Visante optical coherence tomography (OCT), slitlamp (SL) OCT, IOL Master, Pentacam and Orbscan IIz. The statistical significance of interdevice differences between measurements was evaluated by one-way ANOVA and Bland-Altman analysis. The repeatability of 3 consecutive measurements was analyzed by repeated-measures ANOVA. Results: The mean ACD was 2.98 ± 0.29, 2.85 ± 0.29, 3.33 ± 0.42, 2.93 ± 0.30 and 2.80 ± 0.29 mm with Visante OCT, SL-OCT, IOL Master, Pentacam and Orbscan IIz, respectively. All devices displayed a high intrasession repeatability (repeated-measures ANOVA, p > 0.05). ACD measurements obtained by the IOL Master were significantly greater compared to other devices. ACD values detected by Visante OCT and SL-OCT, Pentacam and Orbscan IIz were not clinically interchangeable, even though no statistically significant difference was detected. Conclusion: Although noncontact ACD measurements using all modalities were easy to handle and demonstrated good repeatability, the tested devices were not regarded as compatible. Hence, the clinician should take the different modalities into consideration during ACD assessment using various devices.

Descemet-stripping automated endothelial keratoplasty was safe and effective in eyes with TASS-associated corneal edema, yielding encouraging surgical and visual outcomes.
