Abstract
Purpose :
Seasonal predilection is reported in the occurrence of many systemic and ocular diseases. The aims of the study were to investigate the existence of a relationship between seasonal changes and the incidence of rhegmatogenous retinal detachment (RRD) in mexican patients at Instituto Mexicano de Oftalmología I.A.P. in Querétaro, México, and to analyze the predisposing factors for such relationship.
Methods :
We retrospectively reviewed all cases of RRD during a period of 9 years (June 2007- May 2017). The details regarding demographic profile, clinical features and the month of occurrence of RRD were collected. The different factors were compared with SPSS version 17.0 and X test was used for statistical analysis.
Results :
A total of 286 eyes were diagnosed with RRD,149 eyes belonged to men and 137 to women. Of the men, 76 cases (51%) occurred during spring (p=0.03), 36 (24.1%) during summer (p=0.04), 26 (17.4%) during fall, and 11 (7.3%) during winter. Of the women, 43 cases (31.3%) occurred during spring (p=0.05), 46 (33.57%) during summer (p=0.05), 36 (26.2%) during autumn and 12 (8.7%) during winter. The most affected age group corresponded to patients older than 60 years with 49 cases (32.8%) in the men group and 51 (37.9%) in the women group. Factors suggestive of vitreous dehydration such as posterior vitreous detachment or intraocular pressure were not associated with the seasonal variation.
Conclusions :
Rhegmatogenous retinal detachment shows seasonal variation that presents its peak during spring and summer months. The over 60 years old group was the most affected one.
