Optical coherence Tomography Angiography versus Fundus Fluorescein Angiography in Chronic Central Serous Chorioretinopathy

The detection of a clear vascular network by OCTA was superior to that by FFA. 10 eyes showed as a thick, interlocking filamentous neovascular membrane that was well characterized. Statistics showed that the difference was substantial (P 0.001). Additionally, in our study, the distinct dye leakage patterns of the Chronic CSC on FA did not correlate with the CNV shown on OCTA, supporting the idea that OCTA identifies the choroidal neovascular network by depth and is independent of dye leakage detected on FA. To evaluate and study the role of OCT Angiography in eyes with chronic CSCR with CNV and non CNV group in comparison with fundus fluorescein angiography. This a comparative cross–sectional study. It was performed in AL Zahraa hospital (Al -Azhar University) in the period from March 2021 to Jun 2022. Clinical data and images were obtained from 20 eyes. Ink-Blot pattern was the most common FFA findings like other studies which was found in 8 cases out of 10 (80%) of Chronic CSR without CNV and was found in 9 cases out of 10 (90%) of Chronic CSR with active CNV.  As a non-invasive, quick, and dependable angiographic imaging method, OCTA has advantages over FA. The ability to view the retinal and choroidal vasculature in various layers is another benefit of OCTA. The narrow field of vision of OCTA, inability to detect leakage, difficulty detecting blood flow below a particular level.
