Incidence and Risk Factors of Epiretinal Membrane after Cataract Surgery

초록

Purpose: To investigate the incidence and risk factors of epiretinal membrane (ERM) after cataract surgery. Methods: We reviewed the medical records of patients who underwent cataract surgery between January 2016 and December 2018. Eyes with ERM, as observed by optical coherence tomography performed 1-2 months after surgery, were excluded from the study. ERM was diagnosed by fundus photography. The incidence rate was determined 2-6, 6-12, and 12-24 months after surgery. The cumulative incidence rate of ERM was calculated by Kaplan-Meier analysis. Data were analyzed using logistic regression to determine the associations between ERM development and various factors. Results: The study included 218 eyes of 161 patients with a mean age of 66.6 +/- 9.7 years at the time of surgery. ERM was observed in 3 of 218 eyes (1.4%) between 2 and 6 months, 15 of 176 eyes (8.3%) between 6 and 12 months, and 14 of 150 eyes (10.3%) between 12 and 24 months after surgery. The cumulative incidence rate of ERM was 11.7% over the 24-month period after surgery. In multivariate logistic regression analysis, older age (>= 65 years; odds ratio [OR], 8.59, 95% confidence interval [CI], 1.43-51.49), fellow eye with ERM (OR, 3.63; 95% CI, 1.04-12.73), longer axial length (>= 26 mm; OR, 8.02; 95% CI, 1.08-59.66), and complete posterior vitreous detachment development (OR, 7.48; 95% CI, 1.64-34.14) were significantly associated with ERM development. Conclusions: ERM is not rare after cataract surgery. Long-term retinal examination should be required after cataract surgery.
