Outcomes of macular hole retinal detachment in highly myopic eyes

Abstract

Purpose: To determine the outcome of surgery for retinal detachment (RD) secondary to macular hole in high myopia

Methods: This is a retrospective analysis of 21 eyes with high myopia (more than 6 diptera of axial myopia) that underwent surgery for macular hole associated retinal detachment at the King Khalid Eye Specialist Hospital (KKESH) with at least 6 months follow-up.The main outcome meaures included the visual and anatomical outcomes following surgical management.

Results: Twenty-one eyes of 21 patients (16 female and 5 male) with a mean age of 56.6 (range 15-78) years were reviewed. The mean follow-up was 23 (range 6-143) months. The mean degree of axial myopia was -13.5 (range -6 to -28 D). Seven of the eyes (33%) were pseudophakic and 5 (23%) were aphakic. A posterior staphyloma was present in 9 eyes (42%). All eyes underwent vitrectomy and internal limiting membrane peeling was performed in 13 eyes (62%). The mean preoperative visual acuity was 3/200 (range 20/125-LP) and improved to 20/300 (range 20/50-LP) postoperatively at last follow up. The retina was successfully attached in 20 eyes (95%) after one procedure and in all eyes at last follow-up. The macular hole was closed in 17 eyes (81%) after one procedure and at last follow-up visit. There were no major differences in the rate of retinal reattachment or hole closure between eyes that underwent ILM peeling and those that did not.

Conclusions: Vitrectomy with or without ILM peeling seems to be beneficial in RD due to macular hole in high myopia.
