AIM:To study the choroidal characteristics of CSCR and PCV with EDI-OCT.Methods:This retroprospective observational case series study consisted of patients with CSCR and PCV. Choroidal thickness was measured using EDI-OCT. Both thickness and pachy vessels were confirmed by 3 graders.RESULTS:The study included 41 eyes with 26 eyes showing signs of CSCR and 15 eyes of PCV.The mean subfoveal choroidal thickness was greater(p<0.001) in eyes with CSCR(379.2 µm – 95%CI348.6 – 409.9)compared to eyes with PCV (264.9 µm – 95% CI 212.9 -316.9) EDI-OCT revealed enlargement of the outer choroidal vessels in 15 eyes with CSCR and 14 eyes with PCV (p=0.030). Vision was significantly better in CSCR ( median 76 ETDRS letters range 35-80) versus PCV (median 70 ETDRS ) (p<0.001). CONCLUSION:CSCR is characterized by a increased choroidal thickness as compared to PCV whereas enlargement of underlying outer choroidal vessels was more characteristically seen in PCV as compared to CSCR.
