Rubeosis Iridis Resulting from Agenesis of the Internal Carotid Artery: A Case Report

We report a case of rubeosis iridis resulting from agenesis of the internal carotid artery. Agenesis of the internal carotid artery is a rare congenital anomaly, and most patients do remain asymptomatic, but we should realize that this condition may lead to ocular ischemic changes, the result being rubeosis iridis.

Unilateral agenesis of the internal carotid artery.

Unilateral agenesis of the internal carotid artery (ICA) is an extremely rare anomaly. Diagnosis is often incidental in a radiological examination. Recognition of this anomaly has important clinical implications because other life-threatening conditions can be associated and it must be taken into account when planning carotid surgery. We report a case of 64-year-old man with agenesis of the ICA.

Experimental immunogenic rubeosis iridis.

We have developed a primate model of rubeosis iridis in monkeys systemically sensitized to crystalline beef insulin. After intravitreal insulin injection, the dose-related immunogenic inflammation includes cells, flare, fibrin, and blood in the anterior chamber. With more severe inflammation, posterior synechiae, iris bombé, and cataracts occur. Of particular importance, new blood vessels deve...

Left Internal Carotid Artery Arising from the Right Cavernous Internal Carotid Artery: A Case Report

Anatomical variations involving the internal carotid artery are uncommon. Herein, we present a very rare origin of the internal carotid artery. An adult female presented to the emergency department after falling. Imaging revealed that the left internal carotid artery arose from the contralateral cavernous segment of the internal carotid artery. Such a variation should be kept in mind by radiolo...
