Amaurosis Fugax Syndrome
Amaurosis Fugax Syndrome
General: Caused by malignant hypertension; often occurs in association with heavy smoking; may indicate vascular insufficiency of the vertebrobasilar arterial system; may precede a cerebrovascular accident and not infrequently seen in vascular insufficiency problems of the carotid arterial system; the cause, if found, is commonly an abnormality in the ipsilateral carotid artery or a cardiac source of embolism.
Ocular: Partial blindness in short attacks to permanent complete blindness; scintillating scotoma; teichopsia; retinal arteriolar spasm; signs of arteriolar sclerosis.
Clinical: Malignant hypertension; atherosclerosis; expanding lesions of the frontal or temporal lobe; vascular insufficiency.
