Abstract
Moyamoya disease (MMD) is a distinct entity, mostly found in Japan but cases are reported from many parts of the world. It is an angiopathy involving intracranial distal ends of internal carotid arteries (ICA). It may involve proximal parts of anterior cerebral artery and middle cerebral artery, causing narrowing of lumens resulting in ischaemia and collateral vessels formation. This leads to “puff of smoke” appearance, hence the name Moyamoya. MMD causes cerebrovascular ischaemic events, haemorrhagic strokes and seizures. Minor cases are observed and treated conservatively. Severe cases may need revascularization procedures. In our case report 8 years boy presented with loss of vision and optic atrophy in his right eye. Optic nerve involvement is rare but has been reported previously as well. In these cases monitoring of visual functions may need to done.
Keywords: Moyamoya disease, Optic atrophy, cerebrovascular ischaemic event.
