Abstract. A 36-year-old male presented with impaired vision and visual field in his right eye since 2 months before. His corrected visual acuity was 30 cm counting fingers right and 0.7 left. The right eye showed optic atrophy and positive RAPD(relative afferent pupillary defect). A giant right carotid aneurysm,30×25 mm in size,was detected by cerebral angiography. The aneurysm eventually reduced in size after ligation of common carotid followed by ligation of internal carotid. The visual acuity and field improved thereafter. His visual acuity is 0.09 right and 1.2 left 27 months after his initial visit. Both eyes showed fluctuations in visual acuity and field during the course of the desease,probably due to impaired circulation in the optic nerve in addition to compression of the optic nerve by the giant aneurysm.
