Article Outline

A 66-year-old Taiwanese aboriginal male had complained of right-side blurred vision for 2 months, especially when reading. He had a 10-year history of hypertension and cardiovascular disease. His best-corrected visual acuity was 20/25 in each eye. Ophthalmoscopy revealed asymmetrical cupping, but a normal disc. Humphrey perimetry showed an upper homonymous para-central quadrantanopic defect. Brain magnetic resonance imaging showed an infarction in the left lower calcarine area over the extrastriate (V2/V3) cortical area and a narrowing of the left middle and posterior cerebral arteries due to severe arteriosclerosis.

Key Words:  calcarine fissure , extrastriate cortex , magnetic resonance image , quadrantanopia
