Purpose: To present anatomical and visual results of patients with idiopathic macular holes who had undergone pars plana vitrectomy, internal limiting membrane peeling and gas endotamponade injection and who had postoperative only 24 hour prone positioning.

Materials and Methods: Seventy-eigth eyes of 73 patients with idiopathic macular holes had undergone 20-gauge or 23-gauge pars plana vitrectomy, internal limiting membrane peeling and intraocular gas endotamponade injection. Postoperatively one day prone positioning positioning was recommended. Macular hole closure, late reopening, best corrected visual acuity (BCVA) and complications were noted during postoperative period.

Results: Average age of the patients was 65.8±7.8 (36-83). Macular hole was Stage 2 in 12 eyes (15.38%), Stage 3 in 25 eyes (32.05%), Stage 4 was in 41 eyes (52.56%). After surgery in 74 eyes (94.9%) macular hole was closed. Preoperative BCVA was 0.21±0.20 (Snellen), and postoperative BCVA was 0.45±0.31. Visual improvement was determined in 62 patients (79.48%). Average follow-up time was 22.29±18.34 months.

Conclusion: In patients with macular hole, pars plana vitrectomy, internal limiting membrane peeling, gas endotamponade injection and postoperative only 24 hour prone positioning has high anatomical success and has no significant complications.
