Purpose. To evaluate the relationship between internal carotid artery (ICA) stenosis and subfoveal choroidal thickness (SFCT) in\nthe elderly population. Methods. A total of 42 eyes of 21 patients with more than 70% ICA stenosis (Group 1) on one side and less\nthan 70% stenosis (Group 2) on the other side were recruited for this study. ICA stenosis was diagnosed using both the B-mode\nand Doppler ultrasound.The two groups were compared in terms of the percentage of stenosis, SFCT measurements, intraocular\npressure, ocular perfusion pressure, refractive error, and peak systolic velocity. Eyeswere examined with the RTVue-100OCT device\nby the EDI-OCT technique. Results. The mean age of the patients was 71.9 �± 10.8 years. The mean percentage of ICA stenosis was\n74 �± 4.9% in Group 1 and 47.5 �± 7.7% in Group 2. The mean SFCT was 231.9 �± 44.6
