A 62-year-old female complained of vision
loss following multiple abdominal surgeries for mesenteric ischemia. The
patient’s visual acuity
was no light perception (NLP) in the right eye and hand motion (HM) at 1’ in the left eye. Both pupils were
unreactive and no relative afferent pupillary defect was noted. Anterior
segment and fundus examination were unremarkable. T1 and T2 weighted MRI
imaging of the brain was normal but diffusion weighted imaging (DWI) revealed
areas of bright signal within both intraorbital optic nerves, confirming the
diagnosis of posterior ischemic optic neuropathy.
