Purpose:
The purpose of this study was to report a rare case of retinal reperfusion injury after optic nerve sheath fenestration surgery.
Patients And Methods:
Single patient case report.
Results:
A 58-year-old African American woman presented with severe visual loss in the right eye 2 weeks after optic nerve sheath fenestration surgery. Retinal examination at presentation showed severe arterial narrowing and the appearance of new intraretinal hemorrhages. Fluorescein angiography demonstrated delayed venous filling.
Conclusion:
Severe visual loss after optic nerve sheath fenestration procedure is uncommon. This case may represent the first reported case of reperfusion injury in human eyes.
