    Abstract:
    PURPOSE: To report on the outcomes of 25-gauge pars plana vitrectomy using sulfur hexafluoride and no prone positioning for repair of macular holes. METHODS: Retrospective case series of 44 consecutive patients who underwent pars plana vitrectomy with internal limiting membrane peeling for repair of stages 2 to 4 idiopathic macular holes using 20% to 30% sulfur hexafluoride. No postoperative prone positioning or gas augmentation was used. RESULTS: The macular hole closure rate was 88.6%. There were no differences in the macular hole closure rates between phakic and pseudophakic patients (21 of 23 vs. 17 of 21, respectively) or among stages 2, 3, and 4 macular holes (12 of 13, 20 of 23, and 7 of 8, respectively). In eyes successfully operated on, visual acuity improved from 0.61 logarithm of the minimal angle of resolution (logMAR) (20 of 82) preoperatively to 0.483 logMAR (20 of 61) at 1 month and 0.396 logMAR (20 of 50) at a mean final follow-up of 10.8 months. Adverse effects were elevation of intraocular pressure to >30 mmHg in 7 (13.6%) of 44 patients on the first postoperative day, postoperative retinal detachments in 2 (4.5%) of 44 patients, and progression of cataract requiring cataract surgery in 7 (30.4%) of 23 phakic patients during follow-up. CONCLUSIONS: Macular hole closure rates similar to those achieved using pars plana vitrectomy with perfluoropropane and prone positioning can be achieved using sutureless 25-gauge vitrectomy with sulfur hexafluoride tamponade and no prone positioning for both phakic and pseudophakic patients.
