&Corresponding author
We report the case of a 60-year-old male, treated for hypertension. This patient presented to our hospital with blurred vision in the left eye. His best corrected visual acuity was 10/10 in the right eye and reduced to light perception in the left eye. The anterior segment examination was unre-markable. Fundoscopic examination of the left eye revealed papillay atropy, narrowed retinal ar-teries, and ghost vessls. We can also see some arterial clots. Fundoscopic examination of the right eye was unremarkable. Carotid artery ultrasound found an 80% stenosis in the left eye and a 30% stenosis in the right eye. The syphilis assay was positive. The patient underwent a carotid endarter-ectomy. Daily intramuscular benzathine penicillin was given for 14 days.
