Purpose: To evaluate the safety of oral fluorescein angiography (FA) and to compare its efficacy in detection of macular edema (ME) with spectral-domain optical coherence tomography (SD-OCT). Methods: Results of imaging studies for 1,928 eyes of 1,019 patients who had simultaneously undergone both oral FA and SD-OCT by a confocal laser ophthalmoscope were reviewed. Sensitivity in detecting ME, discrepancy rate, and "kappa" agreement were determined for both the techniques and with eyes stratified by disease diagnosis. Results: No allergic reactions occurred after oral FA. Mild gastric discomfort was noted in <1% of the patients; 1,840 eyes (95 ...

Purpose: Correlating spectral domain optical coherence tomography characteristics with final best-corrected visual acuity (BCVA) in eyes with subfoveal scarring after treatment for wet age-related macular degeneration. Methods: Seventy-nine eyes from 64 subjects, who developed subfoveal scarring after treatment of wet age-related macular degeneration, were retrospectively studied. Spectral domain optical coherence tomography characteristics were analyzed, including percentage disruption of inner segment/outer segment junction and external limiting membrane, central macular thickness, subfoveal scar thickness, subretinal scar area, and proximity of retina with intact outer structures to the fovea. A multivariate stepwise regression analysis was performed with the final BCVA logarithm of ...

Purpose: To evaluate the repeatability and reproducibility of manual choroidal volume (CV) measurements on spectral-domain optical coherence tomography (SD-OCT) using enhanced depth imaging (EDI). Methods: Sixty eyes of 32 patients with or without any ocular chorio-retinal diseases were enrolled prospectively. Thirty-one choroidal scans were performed on each eye centered at the fovea using a raster protocol. Two masked observers demarcated choroidal boundaries using the built-in automated retinal segmentation software on two separate sessions. The observers were masked to each other's and their own previous readings. A standardized grid centered on the fovea was positioned automatically by the Spectralis OCT ...

Purpose To correlate spectral-domain optical coherence tomography (SD-OCT) findings of perfused diabetic microaneurysms with leakage status on fluorescein angiography (FA) using simultaneous FA and SD-OCT. Design Retrospective, observational case series. Methods A total of 173 microaneurysms were analyzed in 50 eyes (14 mild nonproliferative diabetic retinopathy [NPDR]; 22 moderate NPDR; 9 severe NPDR; 5 proliferative diabetic retinopathy) of 40 diabetic patients using simultaneous FA and SD-OCT. The characteristics of microaneurysms were evaluated by 2 masked observers using SD-OCT and correlated with leakage status on FA. Results External diameter of microaneurysms averaged 104 μm (range 43-266 μm). Some microaneurysm centers (15 ...
