Occlusion of the Central Retinal Artery Complicating a Thrombosed Abdominal Aortic Aneurysm: An Exceptional Complication

We report the case a patient who presented a sudden decrease in visual acuity of the right eye secondary to an occlusion of the central retinal artery. In addition, the patient complained of intense abdominal pain for which a CT scan was performed and it revealed a thrombosed aneurysm of the abdominal aorta so the diagnosis retained is occlusion of the central retinal artery complicating a thrombosed aneurysm of the abdominal aorta .Occlusion of the central retinal artery (CRAO) is a very rare vascular pathology. It is often secondary to cardiovascular pathology but it can also be a complication of a distant vascular anomaly, hence the interest of an exhaustive etiological diagnosis and the elimination of vascular emergencies such as thrombosed aneurysms of an artery whatever its location such as abdominal or thoracic aorta , especially in the presence of warning signs. The scientific interest of our case is that the occlusion of the central artery of the retina is rare and exceptionally can complicate a thrombosed aneurysm of the abdominal aorta which is a vital emergency.
