Abstract. Purpose:To report a case of occlusion of internal carotid artery with attacks of amaurosis as the initial manifestation. Case:A 64-year-old male presented with two episodes amaurosis fugax in the foregoing 8 days. He had systemic hypertension and hypertrophic heart disease. Findings:Corrected visual acuity was 1.0 in either eye. Funduscopic findings were normal. Blood flow in ophthalmic artery in the right eye was difficult show by Doppler imaging. Echography showed mild thickening of intima-media complex of carotid arteries. Magnetic resonance angiography(MRA)showed normal findings in the proximal portion of right internal carotid. Cerebral angiography performed 6 weeks after MRA showed complete occlusion of right internal carotid artery. Attacks of amaurosis disappeared after superficial temporal to middle cerebral artery bypass. Conclusion:This case illustrates that attacks of amaurosis may be initial manifestations of occlusion of internal carotid artery.
