Central retinal artery occlusion associated with the G20210A prothrombin gene (F2) mutation: A case report.

Central retinal artery occlusion is a severe vascular condition that can progress to significant disturbances in visual acuity in about 80% of people. In some cases, this event may be associated with genetic variations such as mutations in the prothrombin (F2) gene. Prothrombin is a precursor to thrombin and is essential for the final phase of the coagulation cascade. An alteration in this gene means that it can lead to peripheral thrombophilic disorders as in the case that we want to report.
Our case, a 55-year-old patient, consulted for acute and transient loss of visual acuity in the left eye, also presenting findings of acute ischemia, consistent with macular neuroretinopathy on OCT-Angio. As history, she presented an occlusion of the central retinal artery in the right eye and the diagnosis of the prothrombin (F2) gene mutation G20210A. In this case, a relationship was evidenced between independent risk factors such as genetics, inflammation, and vasculature with central retinal artery occlusion in the right eye and areas of contralateral retinal ischemia. However, although we believe that the cause of the central retinal artery occlusion was due to the G20210A prothrombin (F2) gene mutation, it may be due to the inflammatory response associated with posterior scleritis or due to an embolism. carotid. Our objective is to report the third case, which presents occlusion of the central retinal artery associated with the prothrombin (F2) gene G20210A mutation.
