摘要

AIM: To assess the anatomical and visual outcome of idiopathic macular holes greater than 1000 μm using the inverted internal limiting membrane flap technique.METHODS: This retrospective case series included 5 eyes of 5 patients with idiopathic macular hole with base diameter greater than 1000 μm who underwent inverted internal limiting membrane flap technique along with standard 23 G pars plans vitrectomy with posterior hyaloid detachment and fluid gas exchange with 12%-14% perfluoropropane(C3F8). Preoperative and postoperative visual acuity and spectral domain optical coherence tomography images were evaluated. The main outcome measures were visual outcome and macular hole closure.RESULTS: Mean age was 63.2±8.4y with all 5 subjects being females. Mean duration of symptoms was 11±14 mo with a mean postoperative follow up of 13.2 ±13 mo. The mean base diameter of the macular holes was 1420±84.8 μm(1280-1480 μm). Type 1 closure was achieved in four out of five patients, while one patient had type 2 closure using the inverted internal limiting membrane(ILM) flap technique. Median baseline BCVA was 0.79 log MAR(Snellen’s equivalent 20/120) and median final BCVA0.6 log MAR(Snellen’s equivalent 20/80) with mean visual improvement of approximately three lines improvement. No complications related to surgical procedure were noted.CONCLUSION: The inverted internal limiting membrane flap technique may be promising for very large macular holes with high rate of macular closure and good visual outcome.
