Abstract

Abstract

Purpose: We aim to study the microstructural changes and thickness of individual retinal layers in patients with idiopathic epiretinal membrane (ERM) treated with peeling.

Methods: 47 eyes of 46 patients underwent macular SD-OCT scan before and after ERM peeling. Visual acuity (VA) and central retinal layers thickness were recorded before and at the last follow up visit.

Results: The layers that most have changed and contributed to the reduction of central thickness treated with peeling were the Internal Retinal Layers (IRL): Retinal Nerve Fiber Layer (RNFL), Ganglionar Cell Layer (GCL) and Internal Plexiform Layer (IPL).

Conclusions: Visual acuity improvement was not statistically correlated with CMT or IRL thickness reduction, probably due to a small number of patients. However. alterations in the thickness of each retinal layers are easily obtained and its value as a noninvasive  biomarker of VA warrants further investigation.
