Purpose:
To describe a case of extramacular myelinated retinal nerve fibers disappearing after pars plana vitrectomy for an epiretinal membrane and macular edema.
Design:
Interventional case report.
Methods:
A 61-year-old African-American man with extramacular myelinated retinal nerve fibers underwent pars plana vitrectomy for an epiretinal membrane. A posterior vitreous detachment was present preoperatively. Humidified air was used. A gas bubble was placed for an intraoperative macular hole.
Results:
Nine months after surgery, the myelinated retinal nerve fibers had disappeared.
Conclusions:
Loss of myelinated retinal nerve fibers may occur after vitreoretinal surgery. Possible mechanisms include postoperative nerve fiber layer atrophy or ischemia.
