INTRODUCTION: The aim of this study is to evaluate several factors effecting the outcome of epiretinal membrane surgery.
METHODS: 41 eyes of 40 patients (20 female,20 male) who underwent pars plana vitrectomy (PPV) and epiretinal membrane (ERM) peeling with/without internal limiting membrane (ILM) peeling between November 2001 and October 2005 in Beyoğlu Eye Research & Education Hospital with a minimum follow-up of 6 months were enrolled into this retrospective study. Patients' best corrected visual acuity (Snellen), biomicroscopic, funduscopic and optical coherence tomography (OCT) findings at preoperative, month 1,3,6 and final visit were recorded. Surgical technique (partial 25 gauge vs 20 gauge), ILM peeling, intraoperative dyes or etiology of ERMs were evaluated as separate factors for surgical outcome. Intraoperative, peroperative and postoperative complications were evaluated. SPSS 11.0 was used for statistical analyse and p value < 0.05 was defined as significant.
RESULTS: Mean age of the study group was 63.56 ± 14.96. Mean BCVA increased from 0,28 ± 0,149 to 0,35 ± 0,24 Snellen lines (p: 0,028) at 6th month visit. 18 of 41 eyes (43.9 %) gained ≥ 2 Snellen lines at the final visit. In 17 cases (54.8% ) of phakic eyes, cataract progression was detected. ERM recurrence was significantly higher in ILM-intact group ( 37 % vs 0%) than the ILM-peeled group( p: 0,009 ). There was no anatomical or functional outcome difference between partial 25 gauge and 20 gauge PPV techniques.
DISCUSSION AND CONCLUSION: ILM peeling is significantly effective on reducing ERM recurrences. Postoperatively, cataract progression is the main visual gain limiting factor in the follow-up.
