What is Central Retinal Artery Occlusion?

This Additional Artery Could Provide Relief for CRAO Patients

Around 25 percent of individuals diagnosed with Central Retinal Artery Occlusion (CRAO) possess an additional artery known as the cilioretinal artery. Interestingly, this particular artery can be found in roughly 50 percent of the global population. The cilioretinal artery is considered to be a unique irregularity within the retinal vascular system. In cases where this artery remains unaffected by the patient’s condition, there is a decreased likelihood of vision loss.


CRAO Caused By Embolus

Central retinal artery occlusion (CRAO) is often the result of an embolus, which is a buildup of cholesterol that obstructs the blood flow in an artery. Although this blockage may only last for a short period if it quickly breaks up, it can lead to vision loss if it persists. In some cases, the blockage dissolves naturally, and blood flow is restored, preventing any vision impairment. However, for many patients, the blockage caused by the embolus is permanent. It is important to note that individuals who have suffered from CRAO due to an embolus are at an increased risk of experiencing cerebral stroke and ischaemic heart disease.
