Foveal Thickness Can Predict Visual Outcome in Patients with Persistent Central Serous Chorioretinopathy

Aims: To evaluate relationships between visual prognosis and foveal thickness measured by optical coherence tomography in patients with unilateral persistent central serous chorioretinopathy. Methods: Fifteen eyes of fifteen patients with symptoms for more than 6 months were evaluated on visual acuity and foveal thickness before and after foveal reattachment. Results: Mean age was 49.7 years (range 34-69), symptoms prolonged for 21.8 months (7-36), logarithm of the minimum angle of resolution (LogMAR) was 0.27 (decimal visual acuity 0.53). After foveal reattachment, LogMAR was 0.16 (0.69). Final foveal thickness (mean 109 mu m) was thinner than that of initial presentation (151 mu m) and unaffected fellow eye (144 mu m). Thicker initial foveal thickness compared with fellow eyes had good visual prognosis of 1.0 or more (p = 0.0046). Final visual acuity correlated with initial (r = -0.73) and final (r = -0.81) foveal thickness. Conclusions: Foveal thickness can be a factor predictive of visual outcome in patients with persistent central serous chorioretinopathy. Copyright (C) 2008 S. Karger AG, Basel
