Einfluss der Jahreszeit auf das Auftreten einer Retinopathia centralis serosa

Purpose: We investigate seasonal variations found in patients with central serous chorioretinopathy (CSC). Methods: We retrospectively investigated 201 CSC patients at the Osaka Medical College Hospital from January 2011 to December 2016 and evaluated their seasonal and monthly distributions. Results: The study population comprised 149 males and 52 females. There were significant seasonal differences in the distribution of patients, with 62 cases in spring, 37 in summer, 59 in autumn, and 43 in winter, and the monthly prevalence of CSC was high in March (n = 24), April (n = 22), and November (n = 23). In addition, seasonal variation of serous retinal detachment (SRD) in the macula could be observed in 12 recurrent CSC cases. Conclusions: The prevalence of CSC development was the highest in spring. In addition, recurrent SRD in the macula showed seasonal variation in some CSC patients. As factors related to CSC, season and temperature might influence the pathophysiology of CSC.
