Retinal artery occlusion (RAO) is a severe condition that can lead to sudden vision loss. It occurs when there is a blockage in one of the arteries carrying blood to the retina. This article explores the most common cause of RAO, its implications for eye health, and how New England Retina Associates provides specialized care for this condition.
Understanding Retinal Artery Occlusion
Retinal artery occlusion is similar to a stroke in the eye. We can categorize it into two main types:
- Central Retinal Artery Occlusion (CRAO): Involves blockage of the main artery supplying blood to the retina
- Branch Retinal Artery Occlusion (BRAO): Involves blockage of one of the smaller branches of the main artery
Both types can lead to significant vision loss if not treated promptly.
The Most Common Cause of RAO
The most common cause of retinal artery occlusion is atherosclerosis, which is the hardening and narrowing of the arteries due to the buildup of cholesterol and other materials on the artery walls. This condition can lead to the formation of emboli, which are tiny clots or plaques that can travel through the bloodstream and lodge in the retinal arteries, blocking blood flow.
Risk Factors for Atherosclerosis and RAO
Several factors increase the risk of developing atherosclerosis:
- High Blood Pressure: Damages the blood vessels, making them more susceptible to atherosclerosis
- High Cholesterol: Contributes to the formation of plaques in the arteries
- Diabetes: Accelerates the process of atherosclerosis
- Smoking: Causes damage to the blood vessels and increases plaque formation
- Heart Disease: Increases the likelihood of emboli formation
Symptoms of Retinal Artery Occlusion
RAO typically presents with sudden, painless vision loss in one eye. The severity and extent of vision loss depend on whether the occlusion is in the central or branch artery. CRAO often results in more profound vision loss compared to BRAO.
New England Retina Associates’s Advanced Care
We provide specialized care for patients with retinal artery occlusion. Our approach includes:
Advanced Diagnostic Tools
We utilize state-of-the-art diagnostic technologies, such as OCT and fluorescein angiography, to accurately diagnose and assess the extent of retinal artery occlusion. These tools allow us to visualize the retina in detail and plan effective treatment strategies.
Personalized Care Plans
Each patient receives a personalized care plan tailored to their condition and needs. Our eye doctors work closely with patients to manage underlying risk factors, such as high blood pressure, cholesterol, and diabetes, to prevent further occlusive events. We also collaborate with primary care physicians and cardiologists to ensure a comprehensive approach to health management.
Patient Education and Support
Education is a critical component of our care approach. We provide patients with detailed information about RAO, its causes, and preventive measures. By empowering patients with knowledge, we help them actively manage their eye health and reduce the risk of future complications.
