5Prof. Dr., Dünya Göz Hastanesi, Göz Hastalıkları Servisi, İstanbul - TÜRKİYE Purpose: To assess the effect of internal limiting membrane (ILM) peeling on macular anatomy and function in the patients who underwent a surgery for idiopathic epiretinal membrane (ERM).
Materials and Methods: We studied a retrospective interventional case series of 20 eyes in 20 patients with idiopathic ERM. The study group (n= 10) who underwent ?Pars plana vitrectomy (PPV), ERM removal and ILM peeling - double peeling,? and the control group (n= 10) who underwent ?PPV, ERM removal without ILM peeling - single peeling? were statistically compared with each other by means of visual acuity, multifocal electroretinography, optical coherence tomography and microperimetry.
Results: ILM peeling do not affect the postoperative visual acuity, central macular thickness, microperimetry scores, N1 amplitudes and latancies statistically. However P1 amplitudes in ring1 decreased signifi cantly in ILM peeled eyes (p=0.041). Besides, while foveal contour was recovered in 40% of the control group, none of the ILM peeled eyes had normal foveal contour at the end of the 3rd month.
Conclusion: Although ILM peeling do not reduce the visual acuity, it may result in an additional damage to the muller cells and the inner segments of the retina.
