Characteristics and Seasonal Variations of Rhegmatogenous Retinal Detachment in the Eastern Black Sea Region of Turkey: 8-Year Results
Abstract
Objectives:To assess seasonal variations in the incidence of rhegmatogenous retinal detachment (RRD) in the Eastern Black Sea region of Turkey.Materials and Methods:Patients presenting due to primary RRD to a university hospital operating as a reference clinic in the region between 2011 and 2018 were evaluated retrospectively. Patients’ ages, sex, affected eye, and presentation times were recorded. Years were divided into months, quarters, seasons, and half-year periods, and these periods were analyzed in terms of differences in patient numbers.Results:Two hundred eighty-one eyes of 276 patients meeting the study criteria were included. The patients’ mean age was 60.2 years, and the male:female ratio was 1.35:1. Right and left eye rates were similar. Detachments were most common (49.4%) in the upper temporal quadrant. Eighty-nine patients (31.6%) had undergone uncomplicated phacoemulsification surgery a mean 2.7 years previously. The mean annual case number was 35.13±5.43, and no statistically significant variation was determined in case numbers by year (p=0.558). Analysis of all years revealed a monthly mean case number of 23.42±4.4, with the highest number of cases, 29 (10.3%), being seen in September and the lowest number, 13 (4.7%), in December. No statistically significant monthly variation was determined (p=0.613). Similarly, no statistically significant variation was observed in case numbers analyzed by quarter, season, or half-year (p>0.05).Conclusion:The incidence of cases of uncomplicated RRD does not exhibit seasonal variation in our region. We also think that since 31.6% had a history of cataract surgery, patients undergoing phacoemulsification surgery, even if uncomplicated, should be periodically assessed for detachment.
