Abstract
Study Design: In an observational cross-sectional study, 91 eyes of 46 consecutive patients underwent simultaneous Fundus Fluorescein Angiography (FFA) for common retinal disorders. The FFA images captured by both cameras were graded by 3 Retinologists (DVS, GM, RB) in a structured format. 7 characteristics of FFA images that were used for grading were Foveal Avascular Zone (FAZ) visualization, identifying branch retinal vein, Identification of any abnormal hyper fluorescence at macula, Identification of Micro aneurysms, Identification of capillary non perfusion areas and identification of leakage from retinal neovascularization, Image quality and Impact on Clinical decision. Results were captured and statistically analyzed for interobserver and intercamera agreements.
