Abstract

A 44-year-old woman who showed recurrent vitreous hemorrhages with vascular tortuosity received CT angiography which revealed an internal carotid artery aneurysm. A case of internal carotid aneurysm was associated with a pattern of retinal arteriolar tortuosity pathognomic for familial retinal arterial tortuosity (fRAT), suggesting possible involvement of the cerebral circulation. We present a case of internal carotid aneurysm associated with a pattern of retinal arteriolar tortuosity pathognomic for fRAT.

  Fig. 1 Fundus photography of subject with familial retinal arteriolar tortuosity. (A) Right eye. (B) Left eye. On the patient's first visit to the clinic with decreased visual acuity in the left eye, fundus examination showed marked tortuosity of the second- and third-order retinal arteries in both eyes as well as multiple preretinal hemorrhages in the left eye. (C) Right eye. (D) Left eye. Six months later, the patient noted decreased visual acuity in the right eye and fundus examination showed marked tortuosity of the second- and third- order retinal arteries in both eyes as well as multiple and preretinal hemorrhages in the right eye.
