Macular hole (MH) leading to central vision loss is common in the elderly. This study aimed to explore the anatomical and functional outcome of MH surgery at a tertiary eye care setting in Nepal.METHODSThis retrospective, interventional case series study included patients who had undergone MH treatment with pars plana vitrectomy, membrane peeling and perfluoropropane gas (C3F8) from 2007 January to 2010 August and had completed three months of follow up. The best corrected visual acuity (BCVA) and anatomical status of MH assessed with bio-microscopy and optical coherence tomography (OCT) at six weeks, three months and at the last follow-up following surgery were recorded.RESULTSA total of 36 cases with the age range of 11 - 73 years and the mean age of 53.2 years (19.3 S.D) were included in the study. The mean duration of decreased vision was 11.1 months (12.1 S.D). Idiopathic macular hole comprised of 31 cases (86.1 %) and traumatic of five cases (13.9 %). The mean follow-up period was 9.4 months. The MH closed in 27 cases (75 %) at six weeks and in 28 cases (77.8%) at three months and at the last follow-up. The vision had improved in 36 % of cases, with more than 2 lines in 27.8 %, and was stable in 27.7 % of cases during the the last follow-up. The anatomical success rate was higher in the idiopathic MH (80.65 %) than in the traumatic (60 %) and visual acuity improved in 45 % of cases in the idiopathic and 20 % in the traumatic cases.CONCLUSIONSThe overall anatomic success rate was 78 % and improvement in visual acuity was seen in one -third of cases. The success rate was higher among idiopathic MH than in traumatic.
