Carvounis, M.D., F.R.C.S.C Retina Consultants DC, Washington, D.C. Cullen Eye Institute, Department of Ophthalmology, Baylor College of Medicine, Houston, TX BACKGROUND RESULTS 78 (1) Repair of macular hole (MH) has in the past required prone positioning in the early post-operative period following pars plana vitrectomy; There was no significant difference in anatomic success between phakic (34/36) and non-phakic (19/1 pseudophakic eyes and 1/1 aphakic eye) eyes (p=.99). 1 The requirement for prone positioning has been questioned; 1 Indeed, multiple case series suggest that non-supine The overall macular hole closure rate was 93.% in the 8 positioning results in similar anatomic success rates as prone positioning; eyes of the 4 patients included. Stage II Stage III Stage IV Randomized controlled studies have also shown that for small macular holes the results are similar with non-supine compared to prone positioning; However, most vitreoretinal surgeons in the U.S. still instruct their patients to maintain prone positioning in the early postoperative period; Moreover, it has been suggested that this may not be true in phakic patients; supposedly the gas bubble is smaller in phakic patients and this does not allow adequate coverage of the macular hole; Finally, case series using non-supine positioning commonly use perfluoropropane (C3F8) for endotamponade. OBJECTIVES To compare macular hole closure rates between phakic and non-phakic patients following sulfur hexafluoride (SF6) endotamponade and nonsupine positioning. METHODS BACKGROUND Retrospective, interventional, case series of consecutive patients who underwent vitrectomy with internal limiting membrane peel for macular hole repair using SF6 and nonsupine positioning postoperatively between August 7 and December 1. Excluded were patients who had inadequate gas-fill on the first post-operative day and who were asked to do prone positioning. Rate of closure was 1% for stage II ( of ), 86% for stage III (1 of 14), 91% for stage IV ( of ). BCVA siginificantly improved from.76 logmar (/1) preop to.33 logmar (/4) at the last visit (p<.). Final visual acuity > /4 in 67% and > / in 4% of eyes. We did not identify any variables associated with increased failure rate. 4 3 3 1 34 Phakic Non-Phakic Table 1.

Retrospective interventional case series Consecutive patients who underwent small gauge vitrectomy for macular hole repair with non-supine positioning postoperatively between August 7 and December 1. Excluded were patients who had inadequate gas-fill on the first post-operative day and who were asked to do prone positioning.
The overall macular hole closure rate was 93.% in the 9 eyes of the 4 patients included. Rate of closure was 1% for stage II ( of ), 86% for stage III (1 of 14), 91% for stage IV ( of ). BCVA siginificantly improved from.76 logmar (/1) preop to.33 logmar (/4) at the last visit (p<.). Final visual acuity > /4 in 67% and > / in 4% of eyes.

Macular hole closure rates with non-supine positioning is similar to previous reports with facedown positioning. Visual outcomes significantly improved by an average of 4 lines on ETDRS chart. We believe that our technique with nonsupine positioning for macular holes has excellent outcomes with less discomfort to patients.
