Central retinal artery occlusion (CRAO) is a serious eye condition that occurs when the central retinal artery is blocked and cannot bring oxygen and nourishment to the retina. It is a problem that can lead to sudden and permanent blindness if not treated immediately. If you believe you may be suffering from CRAO, it is important to seek medical attention right away in order to protect and preserve your vision. In this article, we will discuss the causes, symptoms, and treatment options for CRAO.

What Causes Central Retinal Artery Occlusion?
Central retinal artery occlusion can be caused by a variety of factors including a clot in the artery, trauma to the eye, inflammation of the artery, or a tumor. Additionally, it can be caused by high blood pressure, diabetes, hypertension, smoking, or high cholesterol levels.
Recognizing CRAO Symptoms
The main symptom of CRAO is a sudden decrease in vision or complete loss of vision in one eye. Other symptoms include floaters, gradual or sudden vision loss, pain in the eye, and an abnormally large or small pupil.
Treating Central Retinal Artery Occlusion
The primary treatment for CRAO is to reduce the pressure in the eye, improve blood circulation and restore oxygen levels. Additionally, treatments may include anticoagulant medications to prevent further clot formation, laser treatment, a vasodilator to open up the blocked artery, and injections of anti-inflammatory medications. Surgery may also be necessary in some cases.
Maintaining Eye Health
The best way to prevent CRAO is to maintain overall good eye health by eating a healthy diet, exercising, avoiding smoking, and monitoring your blood pressure and cholesterol levels. Additionally, it is important to pay attention to any sudden changes in your vision and to visit an eye doctor regularly.
Central retinal artery occlusion can be a serious and potentially sight-threatening condition. Understanding the causes, symptoms, and treatment options can help you to be better prepared in the event that you or a loved one experiences this eye condition. If you believe you may be suffering from CRAO, it is important to seek medical attention right away.
