CHOROIDAL INFARCTION AFTER OPTIC-NERVE SHEATH FENESTRATION

Purpose: To describe a visual complication of optic nerve sheath fenes tration.Methods: Case review of two patients who underwent seemingly u ncomplicated optic nerve sheath fenestration. Findings: Both patients had a surgical complication that resulted in significant depression of their temporal visual field and development of a wedge-shaped region of subretinal pigmentation in the nasal fundus. Conclusions: Both pati ents had choroidal infarctions as a complication of optic nerve sheath fenestration. Choroidal infarction should be considered in cases of u nexpected loss of visual field after this type of surgery, although th e funduscopic signs that assist in making the diagnosis may not be evi dent for several weeks after surgery.
