Two years results of surgery for idiopathic macular hole

ABSTRACT

PURPOSE: To evaluate preoperative and intraoperative factors affecting the clinical results and determine the effectiveness of the internal limiting membrane in surgery for long standing idiopathic macular holes (stage 2, 3, 4). METHODS: The data were reviewed from a retrospective study on 95 consecutive eyes with idiopathic macular holes undergoing vitrectomy, fluid gas exchange. Forty six of the 95 eyes underwent internal limiting membrane removal surgery additionally. Postoperative follow up was for 2 years. Wilcoxon matched pairs test, Wilcoxon rank test and multiple regression analysis were performed by using SPSS program. RESULTS: The surgery was anatomically successful in 74 of the 95 eyes (77.8%) and 30 of the eyes (31.5%) showed functional success. Preoperative visual acuity and internal limiting membrane removal were important factors affecting postoperative visual outcome in 2 years follow up of the vitrectomy for idiopathic macular holes. Preoperative factors such as age, sex, duration of visual complaints, stage were not found any association with postoperative visual acuity. CONCLUSIONS: Preoperative visual acuity and internal limiting membrane removal were good prognostic factors in idiopathic macular hole surgery. Functional success group showed constant improvement of visual acuity in postoperative 2 years.
