[Prevalence of Epiretinal Membrane Using Optical Coherence Tomography].

PURPOSE: To investigated the prevalence and risk factors of epiretinal membrane (ERM).

SUBJECTS AND METHOD: Five hundred eyes of 500 patients (202 men and 298 women, average age 74.9), who underwent cataract surgery in Otsuka Eye Clinic one or two months before the survey, were examined using spectral-domain optical coherence tomography (OCT).

RESULTS

ERMs were observed in 43 eyes (8.6%) and 31 eyes (6.2%) were diagnosed as idiopathic ERM. Idiopathic ERM was significantly associated with age, but not with gender, best-corrected visual acuity after cataract surgery or diabetes. Only 4.8 percent of idiopathic ERM patients had subjective symptoms detected by the Amsler chart.

CONCLUSIONS

The prevalence of ERM was 8.6% and of idiopathic ERM 6.2%. The most prevalent risk factor of idiopathic ERM was aging.
