Abstract
Abstract: :
Purpose: Macular retinoschisis is an uncommon complication of high myopia. Limited data are available on surgical management of macular retinoschisis associated with high myopia and these reports involve patients with localized retinal detachment. The purpose of the current study is to report visual acuity and optical coherence tomography (OCT) outcomes following surgical management of macular retinoschisis (without retinal detachment) associated with high myopia. Methods: Prospective, interventional, consecutive case series including all patients who underwent vitreoretinal surgery by two vitreoretinal surgeons (IUS, HWF) for macular retinoschisis associated with high myopia. Results: A 53–year–old man and a 31–year–old woman (with 14 and 18 diopters of myopia, respectively) each experienced progressive visual loss over an 18– to 24–month period from a best–corrected visual acuity of 20/30 to a best–corrected visual acuity of 20/200 due to progressive macular retinoschisis. In each case, preoperative OCT demonstrated macular retinoschisis (without retinal detachment) with a central foveal thickness of over 500 microns. Traction from an attached posterior hyaloid was present in one case. Each patient underwent pars plana vitrectomy, removal of the posterior hyaloid, and fluid–gas exchange using 16% C3F8. Eight months postoperatively, best–corrected visual acuity in the eye of the first patient was 20/80 and OCT demonstrated resolution of the macular retinoschisis and a central foveal thickness of 151 microns; 4 months postoperatively, best–corrected visual acuity in the eye of the second patient was 20/60 and OCT demonstrated resolution of the macular retinoschisis and a central foveal thickness of 229 microns. Conclusions: Surgical management of macular retinoschisis without retinal detachment was associated with improved visual acuity and resolution of macular retinoschisis.
