Background:
The aim of the present study was to compare macular hole closure rates of patients with small and medium-sized macular holes who underwent vitrectomy with internal limiting membrane (ILM) peeling combined with ILM flap transposition over the macular hole, compared with classic ILM peeling.
Methods:
This prospective randomized trial was designed as a pilot study with two groups: ILM peeling with ILM flap transposition over the macular hole vs. classic ILM peeling.
Results:
Among 20 patients recruited, complete analysis could be performed for 16 patients. The macular hole closure rates were 100% in both groups, without significant differences with respect to postsurgical subfoveal hyporeflective zones (p = 1.0, Fisher's exact test), postsurgical visual acuity (p = 0.7, t-test), and postsurgical irregularities of the ellipsoid zone (p = 1.0, Fisher's exact test).
Conclusion:
Vitrectomy with ILM peeling combined with ILM flap transposition over the macular hole and classic ILM peeling are both successful methods for the repair of macular holes of small and medium size and are associated with comparable outcomes.
