Relationship between Obstructive Sleep Apnea and Central Serous Chorioretinopathy: A Health Insurance Database Study.

PURPOSE: To evaluate the association between obstructive sleep apnea (OSA) and central serous chorioretinopathy (CSCR).

METHODS

A retrospective, cohort, longitudinal study was conducted using the national health insurance database in Taiwan between 1996 and 2013. Patients diagnosed with OSA were enrolled after exclusion, and a control group with similar age, gender, and major systemic co-morbidities were included in a 1:1 ratio by propensity score matching. The primary outcome is the occurrence of CSCR, and patients with CSCR were categorized via severity for further analysis. The percentage of incident CSCR in the OSA group and control groups and the adjusted hazard ratios (aHR) of CSCR were determined by Cox proportional hazard regression.

RESULTS

There were 13,084 patients enrolled in both the OSA group and control groups, respectively. The total event of CSCR was 50 (0.4%) in the OSA group and 25 (0.2%) in the control group (P < .001). Moreover, the OSA group has an increased aHR of 1.9 (P = .012) for developing CSCR. In the subgroup analysis, patients with OSA aged from 30 to 39 and 50 to 59 demonstrated higher risk of developing CSCR compared to the control group, and the presence of OSA would lead to a higher incidence of mild CSCR (all P < .05).

CONCLUSIONS

OSA patients aged from 30 to 39 and 50 to 59 have a higher risk of developing CSCR, while the severity of CSCR will not be worsen by OSA.
