Long-term macular function in eyes with central serous chorioretinopathy

Purpose: This study aimed to investigate the long-term effects of central serous chorioretinopathy (CSCR) on macular function. Methods: Sixty-two eyes of 31 patients were included in this study All patients were diagnosed with unilateral CSCR at the Retina Unit of the Ophthalmology Department, Trakya University Medical Faculty, and had a post-attack bilateral visual acuity of 6/6 and a follow-up period of a minimum of 6 months. Visual function was assessed using the Amsler grid, 40-hue colour discrimination test, visual field examination by means of Octopus automatic perimeter and Cambridge contrast sensitivity tests. Results: Of the 31 patients, 71% were men and 29% were women, with a mean age of 39.3 +/- 7.6 years. The patients had a mean follow-up period of 50.6 +/- 40.5 months after the acute attack. Metamorphopsia was observed in 67.7% of the cases with CSCR. A colour discrimination defect was found in 48.4% of the CSCR eyes and in 54.8% of the fellow eyes. As compared with the fellow eyes, the mean deviation in the central 10 degrees of visual field was significantly higher (t = 2.9, P = 0.007) and the mean contrast sensitivity score was significantly lower (t = -3.2, P = 0.004) in the CSCR eyes. Discussion: Patients with unilateral CSCR were observed to have long-term bilateral colour discrimination defects, and eyes with clinical CSCR were determined to have central relative scotoma and loss of contrast sensitivity.
