Although central retinal artery occlusion is rare, it is an important cause of vision loss in the elderly. The incidence is estimated to be 1 in 100,000 people and accounts for 1 in 10,000 ophthalmological outpatient visits.The most likely etiology of a CRAO in general and to this case is a cholesterol embolus (Hollenhorst plaque). Hollenhorst plaques are typically refractile and orange and located at a bifurcation. They arise from ulcerated atheromas from the carotid arteries. Patients with CRAO typically present with an acute, painless loss of vision, and 80% of affected patients have a final visual acuity of counting fingers or worse. Thromboangiitis obliterans (TAO) also known as Buerger’s disease is a segmental occlusive inflammatory condition of arteries and veins, characterized by thrombosis and recanalization of the affected vessels. It is a nonatherosclerotic inflammatory disease affecting small and medium sized arteries and veins of the upper and lower extremities.Here we present the very first case of central retinal artery occlusion (CRAO) in a 64-year-old male patient with Buerger’s disease.
