Abstract

Purpose: To determine the incidence of central serous chorioretinopathy (CSC) stratified by age, sex, and diagnosis with obstructive sleep apnea (OSA), and to determine whether some patients with newly diagnosed CSC may be candidates for OSA evaluation. Design: Retrospective cohort study. Methods: We used the IBM MarketScan database to select 59,016,145 commercially insured patients in the United States between 2007 and 2016. We identified patients' first diagnosis with CSC, and defined patients as having OSA if they had a diagnosis following a sleep study. We specified Cox proportional hazard models with interactions between age, sex, and OSA status to determine patients' risk of developing CSC. We estimated the positive predictive value (PPV) that a new diagnosis of CSC would have in predicting a subsequent diagnosis of OSA. Results: Risk of CSC increased with age in years (hazard ratio [HR] = 1.030, P < .001) and OSA diagnosis (HR = 1.081, P < .033), and was lower in women (HR = 0.284, P < .001). We estimated the annual incidence of CSC was 9.6 and 23.4 per 100,000 women and men, respectively. Incidence was higher in women and men with OSA (17.2 and 40.8 per 100,000). The PPV of CSC diagnosis as a predictor of OSA was highest in the fifth decade of life. Conclusion: The incidence of CSC in our patient sample is higher than previously reported. Risk of CSC is higher in men than in women, and OSA increases risk of CSC in both men and women. Some patients, particularly older male patients, may be good candidates for OSA evaluation following a CSC diagnosis.
