To determine whether small macular hole closure can be achieved with 25-G vitrectomy surgery with internal limiting membrane peeling without the use of intraocular gas tamponade or facedown positioning.
25-G vitrectomy surgery with internal limiting membrane peeling without the use of intraocular gas tamponade or positioning was performed on 20 eyes with a small (<400-µm diameter), full-thickness macular hole.
In 17 of 20 eyes (85%), the hole had closed. Three holes had closed by Postoperative Day 1, 13 holes by Postoperative Week 1, 16 holes by Postoperative Week 2, and 17 holes by Postoperative Week 6. At Postoperative Month 1, vision improved in 16 of 17 eyes in which the macular hole had closed. One hole that had not closed at the first postoperative week and two holes that had not closed at the third postoperative week required follow-up surgery with intraocular gas tamponade and facedown positioning, after which the hole closed. The mean preoperative visual acuity was 0.626 logMAR (20/85), and the mean postoperative visual acuity after 1 month was 0.392 logMAR (20/50) (P < 0.001).
Vitrectomy surgery with internal limiting membrane peeling without the use of gas tamponade or positioning can achieve closure of small macular holes.
