Choroidal infarction after optic nerve sheath fenestration.
OBJECTIVE
To describe a visual complication of optic nerve sheath fenestration.


METHODS
Case review of two patients who underwent seemingly uncomplicated optic nerve sheath fenestration.


RESULTS
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 patients had choroidal infarctions as a complication of optic nerve sheath fenestration. Choroidal infarction should be considered in cases of unexpected loss of visual field after this type of surgery, although the funduscopic signs that assist in making the diagnosis may not be evident for several weeks after surgery.
