Results of Vitrectomy in Idiopathic Macular Hole

To evaluate the visual and anatomical outcomes and complications of vitrectomy with or without removal of internal limiting membrane (ILM) in idiopathic macular hole (IMH) at Labbafinejad Medical Center, Tehran-Iran, 1993-2003. Hospital records of patients who had undergone vitrectomy for IMH and completed 6 months of follow up were reviewed for demographic data and outcomes of surgery. The study was conducted on 30 eyes (46.7% right eyes) of 29 patients (69% female) with mean age of 65.25.6 years. Mean duration of symptoms was 3.23.7 months (66.7% less than 6 months). Preoperatively macular holes were in stages 2, 3, and 4 in 3.0%, 36.7%, and 33.3%, respectively. ILM removal was performed in 21 eyes (70%). Mean visual acuity was 0.990.6 LogMAR preoperatively which reached to 0.870.39 LogMAR postoperatively (P=0.05). Single operation anatomical success rate was 80% (24 eyes) and final success rate was 86.7% (26 eyes). Retinal breaks developed in 3 eyes (10%) intraoperatively. ILM removal had no effect on increasing the rate of macular hole closure. ILM removal has no significant role on closure of IMH with less than 6 months of duration.
