Purpose:To present a case of a patient with decreased visual acuity and anterior ischemic optic neuropathy diagnosed with advanced Moyamoya disease.
Case Summary:A 46-year-old woman presented sudden episodes of headache and decreased visual acuity. On her first visit, her best corrected visual acuity was 20/25 in the right eye and 20/70 in the left eye. The left eye pupil was dilated with a relative afferent papillary defect. Fundus examinations revealed disc swelling in the left eye. After being admitted, steroid pulse therapy was started and Magnetic Resonance Imaging (MRI) studies revealed Moyamoya disease. The diagnosis was confirmed via Magnetic Resonance Angiography (MRA). After steroid pulse therapy, the headaches and visual acuity improved and the patient is continuing follow-up visits at neurosurgery and ophthalmology clinics.
Conclusions:Patients with Moyamoya disease may initially present symptoms and signs of anterior ischemic optic neuropathy.
