Purpose: To evaluate the effect of internal limiting membrane (ILM) peeling on anatomical and functional results in pars plana vitrectomy (PPV) performed eyes with tractional retinal detachment affecting the macula due to diabetes mellitus (DM).
Methods: Patients without ILM peeling were considered as Group 1, and with ILM peeling were considered as Group 2. The main outcomes were the best-corrected visual acuity (BCVA) at 6 months, and the rate of epiretinal membrane (ERM) formation within 6 months. The rate and the indications for resurgery were determined. Parameters affecting final BCVA were determined by regression analysis.
Results: Final BCVA was significantly better in eyes with ILM-peeled off than in eyes with no peel-off (p=0.012). Less secondary ERM was formed in Group 1 (p=0.009). There was no difference between groups in terms of resurgery rates. (p=0.143). The need for resurgery due to ERM was higher in Group 1 rather than Group 2 (p=0.001). The only factor affecting final BCVA was ILM peeling.
Conclusion: In patients with tractional retinal detachment affecting the macula due to diabetes, ILM peeling in addition to PPV and membrane excision does not affect the need for resurgery but contributes positively to anatomical and functional outcomes.
