PURPOSE: To investigate the role of vitrectomy without prone posturing in the anatomic and functional outcome of macular hole surgery (MHS). METHODS: Forty-one consecutive eyes of 41 patients with stage II-IV full-thickness macular holes underwent pars plana vitrectomy and 16% C3F8 tamponade. In 25 cases posturing group (P), subjects were instructed to assume prone positioning for 10 days postoperatively, whereas in 16 cases non-posturing group (NP) patients were advised to avoid lying supine but no other posturing instructions were given. Preoperative, intraoperative and postoperative clinical data were collected, with macular hole closure rate and change in LogMAR visual acuity, contrast sensitivity, metamorphopsia, and 25-Visual Function Questionnaire (VFQ-25) being the primary outcome measures. RESULTS: Over a mean follow-up of 4.21.2 months, anatomical hole closure was noted in 22/25 (88%) and 14/16 (87.5%) in groups P and NP respectively. Visual acuity improved by a mean of eight letters and there was no significant difference in the two groups (P=0.724). Similarly, postoperative prone posturing did not have an effect on the final contrast sensitivity, metamorphopsia, and VFQ-25 composite scores (P=0.238, P=0.472, and P=0.87, respectively). However, eyes in group NP developed significantly more severe cataract in the early postoperative period (P=0.02). CONCLUSIONS: Prone posturing following MHS provides no functional or anatomic benefit but it is associated with slower progression of cataract. Combined phacovitrectomy without face down positioning may be considered for all phakic patients undergoing MHS.
