Thirteen (22.4%) developed cortical blindness associated with a delayed contralateral occipital infarction. Advanced age, general vascular risk, a history of strokes, Sylvian border-zone extension of the initial infarct, and an absence of improvement of initial visual field defects were strongly associated with spread to the other side.

Damage to them may cause deformation of the visual field and of perception of size, color and shape. More specific:

occlusion of a certain occipital artery may cause varying clinical signs and symptoms in different patients. The neurologic deficits that may occur following the isolated occlusion of individual occipital branches of the posterior cerebral artery are discussed.

Another cause of Sudden Blindness is vitreous haemorrhage in which blood leakage occurs. Rare causes of sudden loss of vision include a retinal migraine in one eye.
