Internal Limiting Membrane Removal in Macular Hole Surgery

Objective:To observe whether the vitrectomy combined with internal limiting membrane(ILM) peeling or without ILM peeling is more suitable for macular hole.Methods:We studied 40 eyes of 39 patients with an macular hole.The patients were divided into group A(20 eyes of 20 patients) who underwent the vitrectomy combined with ILM peeling and group B(20 eyes of 19 patients) who underwent vitrectomy surgery.Routine examinations were conducted during the 6-month follow-up period.The best corrected-visual acuity,visual field,electroretinogram and optical coherence tomography(OCT) were checked after surgery.Results:There was no statistics difference in best corrected-visual acuity between the two groups before surgery.The best corrected-visual acuity,visual field,ERG and number of closed hole after surgery in group A were better than that in group B.The VEP findings between the two groups at 6 months post-treatment were comparable.Conclusion:The vitrectomy combined with ILM peeling is more suitable than the vitrectomy for macular hole.
