The use of internal limiting membrane maculorrhexis in treatment of idiopathic macular holes.

The purpose of this study was to assess surgical results of internal limiting membrane (ILM) maculorrhexis in macular hole surgery. This study is a part of continuing prospective clinical trial of our team of researchers. Thirteen eyes of 13 patients with idiopathic macular hole underwent vitrectomy with the removal of posterior cortical vitreous, peeling of the macular ILM, and intraocular gas tamponade, followed by postoperative face-down positioning. The excised specimens were evaluated with transmission electron microscopy. Complete closure of the hole was observed in all 13 eyes (100% anatomic success rate). Visual improvement of 2 or more lines on ETDRS visual acuity chart was achieved in 11 (85%) of the 13 eyes. Six (54.5%) eyes attained visual acuity of 20/50 or better. Electron microscopy showed ILM in the removed specimens. ILM maculorrhexis is a promising new surgical approach to close idiopathic macular holes but requires further investigation and long-term evaluation.
