The Evaluation of Prognostic Factors after Vitrectomy for Idiopathic Macular Hole with OCT

ABSTRACT

PURPOSE: To evaluate the prognostic factors that predict visual outcome in eyes with successfully repaired idiopathic macular hole (MH) using optical coherence tomography (OCT). METHODS: We studied 48 eyes with stage 3 or 4 idiopathic MH that had undergone vitrectomy. All cases had anatomic closures and were followed-up for 6 months or more. We analyzed the preoperative macular hole in terms of minimum diameter, stage, hole form factor (HFF), and macular hole index (MHI), as well as the postoperative OCT images of the repaired macular hole and their relevance to visual recovery. RESULTS: We found significant differences in the preoperative minimum diameter of MH, HFF, the postoperative OCT images of the repaired macular hole, and postoperative visual acuvity. In contrast, we found no statistically significant differences in the preoperative base MH diameter, stage, HFF, MHI, and their relevance to visual recovery. CONCLUSIONS: Minimum diameter of MH, HFF, and the postoperative OCT images of the repaired MH are significant prognostic factors after vitrectomy for the treatment of idiopathic MH.
