To examine the retinal thickness after vitrectomy for epiretinal membrane (ERM) with and without internal limiting membrane (ILM) peeling.
In a non-randomized, retrospective chart review. Vitrectomy with or without ILM peeling was performed for ERM between June 2009 and October 2012. All patients were followed for 12 months. The retinal thicknesses of the nine Early Treatment Diabetic Retinopathy Study (ETDRS) areas (central, inner superior, inner temporal inner inferior, inner nasal, outer superior, outer temporal, outer inferior, outer nasal) were measured by spectral domain optical coherence tomography (Cirrus). The retinal thicknesses of the nine areas were compared between with-ILM peeling group and without-ILM peeling group. Best-corrected visual acuity (BCVA) was measured with Landolt chart before and at 12 months after surgery.
Vitrectomy with ILM peeling was performed in 49 cases and vitrectomy without ILM peeling was performed in 46 cases. The retinal thicknesses of any nine areas before the vitrectomy had no significant differences between the two groups. Visual acuity before the vitrectomy had no difference between the two groups. The retinal thicknesses of any nine areas at 12 months after vitrectomy had no significant differences between the two groups. Visual acuity after 12 month had no difference between the two groups.
These results suggest that ILM peeling for ERM may not have influence on anatomical and functional outcomes at 12 month after vitrectomy.
