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.

Secondary Vitrectomy with Internal Limiting Membrane Plug due to Persistent Full-Thickness Macular Hole OCT-Angiography and Microperimetry Features: Case Series

“…The usability of microperimetry is proved in many articles, and authors put effort to find potential predictive factors for assessment of future and existing treatment [ 33 , 34 ], so it seems reasonable to perform it before vitrectomy. In a recent study of Kunikata and colleagues, microperimetry was performed preoperatively and 1, 3, and 6 months postoperatively in 21 patients with primary FTMH.…”

Vertical and Horizontal M-Charts and Microperimetry for Assessment of the Visual Function in Patients after Vitrectomy with ILM Peeling due to Stage 4 Macular Hole

“…At final follow-up period, we got the result of 100% VA improvement. It is a satisfactory outcome because Leisser et al had BCVA improved in 83% of the cases and Amram et al reported that 86% of eyes had improved BCVA at the final follow-up period of 1 year [13, 14]. Although percentage of patients with BCVA improvement is very important, it is necessary to estimate the level of final correction.…”

Evaluation of retinal functional changes after macular hole surgery using heavy brilliant blue G dye for internal limiting membrane staining: A prospective, single blind, randomized controlled trial

“…[ 20 ] In this regard, MP can help determination of point to point retinal sensitivity and provides specific functional information of the macula and visual restoration after hole surgery. [ 21 22 23 ] Previously, several authors have demonstrated significant improvements in functional parameters measured on MP after successful MH surgery with ILM peeling. [ 19 20 24 25 26 27 28 29 30 ] After postoperative closure of the MH, the fixation status of eyes may show a complex reorganization, and fixation may become more stable with follow-up.…”
