BACKGROUND: Epiretinal membranes are a common finding in people over the age of 50 years. Clinically, they usually cause minor visual distortion. However, in some patients, there may be a significant visual loss and/or metamorphopsia and surgery may be required in more severe cases. CASE HISTORY: In this report, we document the findings of a patient having an epiretinal membrane with macular pucker. The patient underwent surgery consisting of posterior vitrectomy and peeling away of the membrane. DISCUSSION: The classification and terminology commonly used to describe epiretinal membranes are reviewed. In addition, the aetiology, prevalence, symptoms, differential diagnosis, treatment and complications of epiretinal membranes are discussed.
