Vitreous surgery may serve as prophylaxis against macular holes in some eyes

Foveal detachment and retinoschisis resolved after vitrectomy in highly myopic eyes in a recently reported case series. This led the authors to suggest that vitrectomy may serve as a prophylactic treatment for some eyes at high risk of developing a macular hole.
Hideo Kobayashi, MD, and Shoji Kishi, MD, of the Gunma (Japan) University School of Medicine, performed vitreous surgery on nine highly myopic eyes with posterior staphyloma with foveal detachment and retinoschisis without macular hole. Postoperative follow-up ranged from 6 to 42.5 months.
In eight of nine eyes, foveal detachment and retinoschisis gradually decreased in height, and the eyes attained foveal attachment and visual improvement within 6 months postop. One eye developed a full-thickness macular hole during vitreous surgery; best corrected visual acuity in this eye was 0.08 postop.
The study is published in Ophthalmology.
