One-Year Results after Internal Limiting Membrane Flap Transposition for Surgical Repair of Macular Holes with Respect to Microperimetry

Abstract

Purpose: Internal limiting membrane (ILM) flap transposition in surgical repair of macular holes represents a new technique offering good anatomical success rates with large macular holes. The aim of the study was to examine microperimetric outcomes 1 year after ILM flap transposition for surgical repair of macular holes. Methods: Patients with idi­opathic macular holes scheduled for 23-G pars plana vitrectomy with ILM peeling, ILM flap transposition, and SF₆ tamponade were examined in a prospective case series. Distance corrected visual acuity (DCVA), optical coherence tomography, and microperimetry were measured before and 1 year after surgery. Results: In all eyes, closure of the macular hole could be achieved. While foveal sensitivity improved in 71%, perifoveal sensitivity improved in 86% of the cases. DCVA improved in 83% and was unchanged in 17% of the cases. Conclusions: Beside visual acuity, foveal and perifoveal macular sensitivity improved, underlining the functional success of surgery after ILM peeling with ILM flap transposition.
