Purpose:

To report the clinical features and macular morphology by using optical coherence tomography (OCT) in patients with epiretinal membrane (ERM)

Methods:

A retrospective review of 49 eyes of 40 patients with a macular ERM was performed. In OCT, three characteristics were considered in each image: presence of foveal depression, presence of cystoid macular edema and mean central macular thickness.

Results:

The mean age of patients was 64,60 years, 21 were male and 19 female. Mean follow up period was 7,2 months. 18 patients had systemic diseases including diabetes mellitus and hypertension, 1 had ankylosan spondilitis and 1 patient had scleroderma. Idiopathic ERM was seen in 29 eyes, secondary ERM in 20 eyes which were due to diabetes mellitus in 6 eyes, branch retinal vein occlusion in 2, central retinal vein occlusion in 4, trauma in 1, retinal detachment in 2, retinal tear in 2, age related macular degeneration in 2 patients. Macular ERM was bilateral in 9 patients. The mean best corrected visual acuity was 20/ 50 Snellen Unit. On OCT all eyes maintained increased central thickness, ranging from 290 to 370 microm. Cystoid macular edema was identified in 31 eyes, foveal depression was observed in 29 eyes. The capsular pseudoexfoliation was noticed in 6 eyes with epiretinal membrane

Conclusion:

OCT together with careful clinical examination is a sensitive tool in evaluating the ERM.
