Background:
The literature remains controversial regarding seasonal variation of rhegmatogenous retinal detachment (RRD).
Methods:
In this retrospective chart review, seasonal variation of RRD was examined based on the records of 211 consecutive patients operated for idiopathic RRD in one referral medical center over a 13-year period.
Results:
The number of eyes with RRD recorded per season was 46 in autumn, 46 in winter, 62 in spring and 57 in summer. There was a significant seasonal variation (p < 0.05) with an increase in RRD in the warm seasons (spring and summer) compared to the cold seasons (winter and autumn; 56 vs. 44%). Right eyes were more likely to be affected than left eyes (54 vs. 46%), and cases presented with a significantly younger age at onset in the warm than in the cold seasons (47 vs. 54 years, p = 0.007). A literature review of 8,533 cases including the present case series established further the seasonal variation of RRD (p < 0.001).
Conclusion:
There is convincing evidence for a seasonal variation of RRD in Lebanon and in the literature. This is likely to be related to sun exposure and outdoor activities in the warm seasons.
