Abstract

Background: Central serous chorioretinopathy (CSCR) is a common maculopathy that features choroidal circulatory disturbance. This population-based cohort study aimed to explore the relationship between CSCR and the future development of ischaemic stroke. Methods: Data were obtained from Taiwan's national health insurance research database. From 2000 to 2007, 1814 patients with newly diagnosed CSCR were eligible for inclusion in the study cohort. Using stratified random sampling, 9648 enrollees matched with the study subjects in terms of sex, age, monthly income, geographical location and time of enrolment were selected as the control group. Stroke-free survival analysis was assessed using a Kaplan-Meier method. Cox proportional hazard regressions were performed to calculate the HR of ischaemic stroke for the two groups after adjusting for possible confounding variables. Results: Of the sampled patients, 45 (2.5%) from the CSCR cohort and 157 (1.6%) from the control group developed ischaemic stroke during a mean follow-up period of 3.9±2.2 years. CSCR patients had a significantly higher incidence of ischaemic stroke than those without a diagnosis of CSCR ( p=0.003). After adjusting for age, sex and chronic comorbidities at baseline, CSCR patients were found to have a 1.56-fold (95% CI 1.11 to 2.18, p=0.010) greater risk of a subsequent ischaemic stroke than the matched controls. Conclusions: CSCR is an independent indicator for the increased risk of subsequent ischaemic stroke development.
