PURPOSE: To evaluate the prognosis of chronic central serous chorioretinopathy (CSC) and to assess whether certain clinical and angiographic features are associated with increased risk of vision loss. METHODS: All of the 51 patients with chronic CSC, who had received a baseline evaluation with fluorescein angiography (FA) and indocyanine green angiography (ICGA), during the last 5 years were retrospectively included in the study. RESULTS: The mean age was 49 years (range: 28-77 years). Sixteen out of 102 eyes (15.7%) of 14 patients lost at least 3 lines (0.3logMAR) after a mean follow-up of 34.7 months (range: 12-72 months). Logistic regression showed that CSC onset more than 7 years before inclusion (odds ratio: 4.3, p=0.024) and having areas of confluent RPE atrophy with FA at baseline (at least 2 disc diameters, odds ratio: 4.9,p=0.020) were independently associated with vision loss. Choroidal neovascularization was observed during follow-up in 4 eyes of 3 patients. CONCLUSION: Disease duration of more than 7 years and the presence of confluent RPE atrophy independently characterized CSC patients at higher risk for visual loss in our series.
