Purpose: In this study, we aimed to evaluate the relation between obstructive sleep apnea (OSA) and central serous retinopathy (CSR).

Methods: Twenty-three consecutive subjects aged >18 years with the diagnosis of CSR were included in this prospective study. Overnight polysomnography was performed to all subjects. Desaturation index and apnea-hypopnea index (AHI) were recorded. Obstructive sleep apnea was classified according to AHI as mild, moderate, or severe. Statistical analysis was performed using chi-square test, Fisher’s exact test, and Mann–Whitney U test.

Results: Fourteen of 23 CSR patients (60.9%) had OSA. Prevalence of OSA was significantly higher in male subjects with CSR compared to female subjects with CSR (p = 0.018). One (16.7%) female subject with CSR had OSA whereas thirteen (76.5%) male subjects were found to have OSA. Desaturation index was found to be 5.1 ± 4.2 …
