Abstract

A brain arteriovenous malformation (AVM) is a tangle of blood vessels that connects arteries and veins in the brain. There is an inherent high risk of bleeding of the abnormal blood vessels that can cause neurological damage. One of the more serious neurological signs and symptoms of AVM includes vision loss if the site is in the occipital lobe involving the visual pathway. A 32-year-old female presented with sudden onset of blurring of vision associated with severe headache for which she went for detailed ophthalmic evaluation. Vision was 6/6 for both eye without any aid; IOP was 18 and 19 mmHg for right and left eye respectively. Fundus findings were within normal limit. 30-2 field test finding revealed left superior quadrantic hemianopia. She was advised for MRI brain (plain and contrast) and subsequent Cerebral DSA with 3D rotational angiogram which diagnosed right occipital AV malformation. She is currently on regular follow up and being planned for gamma knife radiation therapy.
