Retinal Artery Occlusion Secondary to Buerger's Disease (Thromboangiitis Obliterans).

Purpose. To report a case report of one patient suffering from retinal artery occlusion secondary to Buerger's disease, in order to raise awareness to this etiology in the differential diagnosis of retinal artery occlusion. Methods. A retrospective case report of a patient with retinal artery occlusion secondary to Buerger's disease. Data retrieved from the medical records included exposure, complaints, visual acuity, clinical findings and imaging, laboratory assessment, treatment, disease course, and visual outcome. Results. Diagnosis of retinal artery occlusion secondary to Buerger's disease was established based on ruling out other causes of retinal artery occlusion. Inflammatory retinal vascular disease, permanent vision loss, and macular atrophy were shown in this case. Conclusion. The very first case of central retinal artery occlusion (CRAO) in a 64-year-old male patient with Buerger's disease. Although diagnosing CRAO based on both fundoscopic and fluorescein angiographic findings is not difficult, revealing underlying condition of CRAO occasionally could be challenging.
