Visual symptoms are frequently encountered in the patient with cerebrovascular disease(CVD), whereas these complaints are frequently neglected by the clinician if it occurs in a single eye. Among the visual symptoms following CVD, ischemic optic neuropathy(ION) implies visual disturbances associated with inadequate blood supply of the optic nerve. Vascular insufficiencies involving the optic nerve have three common mechanisms as the CVD, thrombotic, embolic, and hypoperfusion. Monoocular blindness is one of the most frequent complaint of ION, which commonly arises from the opthalmic artery insufficiency. Acute or transient monocular blindness is an ominous sign of following cerebral ischemia, hence early diagnosis and vigorous treatment has an immense significances. Central retinal artery occlusions(CRAO) is usually embolic in nature, and results poor consequencies. Early and accurate diagnosis of ION is important in the treatment and prevention of following CVD.
