California Retinal Artery Occlusion

Are you looking for a retinal artery occlusion specialist in California?

At Retina Associates of Orange County, we are board-certified retinal care providers with over 23 years of clinical experience in California.

If sudden vision loss in one eye, a dark shadow across your visual field, or painless blurriness has appeared without warning, a retinal artery occlusion may be responsible. This condition occurs when blood flow to the retina is blocked, and it requires timely evaluation from a fellowship-trained retinal specialist. Our physicians hold board certifications through the American Board of Ophthalmology and have completed vitreoretinal fellowships at programs including UC San Diego, Weill Cornell, and Bascom Palmer. Our California retinal artery occlusion specialist can evaluate your symptoms and guide appropriate treatment. Schedule an appointment at one of our Orange County offices.

Retinal Artery Occlusion Specialist in California

A retinal artery occlusion occurs when blood flow through one of the retinal arteries is blocked by a clot or atherosclerotic plaque. The retina depends on constant blood flow to function. Even a brief interruption can cause permanent damage. The two primary forms are central retinal artery occlusion (CRAO), which blocks the main artery and often causes complete vision loss in the affected eye, and branch retinal artery occlusion (BRAO), which involves a smaller branch and typically produces partial visual field loss.

California has one of the largest adult populations living with diabetes and cardiovascular disease in the United States. According to CDC diabetes data, approximately 12 percent of American adults carry a diabetes diagnosis, and California’s size means millions of residents face elevated risk for retinal vascular occlusion. Risk also increases as aging affects the retina and its blood vessels become more susceptible to blockage. Working with a retina specialist who treats vascular conditions is essential to protecting your sight.

Retinal Artery Occlusion Services We Offer in California

Retina Associates of Orange County provides diagnostic and treatment services for patients experiencing retinal artery occlusion throughout California. Our offices in Laguna Hills, Newport Beach, and Santa Ana are staffed by fellowship-trained vitreoretinal physicians and equipped with advanced retinal imaging technology.

• Central retinal artery occlusion evaluation. CRAO affects the main artery feeding the entire retina and typically presents as sudden, painless vision loss in one eye. Our physicians perform urgent assessments with dilated exams and retinal imaging to determine the severity of ischemic damage and identify the underlying cause.
• Branch retinal artery occlusion management. BRAO blocks one of the smaller arterial branches, often producing a blind spot or partial field loss. Treatment centers on identifying systemic risk factors such as hypertension or carotid stenosis and monitoring for neovascularization or other secondary complications.
• Retinal vein occlusion care. Venous and arterial occlusions share many of the same underlying vascular risk factors, including high blood pressure and diabetes. We evaluate and treat both forms of retinal vascular occlusion under one roof, which allows for a more complete picture of each patient’s vascular health.
• Fluorescein angiography. This imaging study traces dye through the retinal blood vessels, pinpointing the exact site of a blockage and revealing whether surrounding tissue has lost perfusion. It remains one of the most important diagnostic tools in retinal artery occlusion assessment.
• Optical coherence tomography. OCT generates high-resolution, cross-sectional images of the retina. For patients with a retinal artery blockage, it measures retinal thinning and edema with precision, helping guide treatment decisions and track changes over time.
• Anti-VEGF injection therapy. When an occlusion triggers abnormal blood vessel growth or secondary macular edema, anti-VEGF injections can help stabilize vision. These medications are delivered in-office and target the biological pathways driving swelling and vascular proliferation.
• Retinal laser photocoagulation. Laser treatment may be necessary when a retinal artery occlusion causes neovascularization. The procedure targets affected retinal areas to slow abnormal vessel growth and lower the risk of vitreous hemorrhage and further vision loss.
• Systemic risk factor coordination. Retinal artery occlusions frequently reflect underlying cardiovascular disease, carotid artery stenosis, or diabetic retinopathy. Our physicians coordinate with your cardiologist or primary care provider to address root causes and reduce the chance of a second vascular event.

Understanding Retinal Artery Occlusion Care

Conditions We Treat and Treatment Options

A retinal artery occlusion does not happen in isolation. It is connected to a broader network of systemic vascular conditions, and a thorough evaluation always looks beyond the eye itself. The following conditions are commonly associated with or identified alongside a retinal artery blockage:

• Hypertension and hypertensive retinopathy
• Carotid artery disease and atherosclerosis
• Atrial fibrillation and other cardiac arrhythmias
• Diabetic vascular eye disease and complications from poorly controlled blood sugar
• Giant cell arteritis, especially in patients over 60
• Blood clotting disorders and hyperviscosity syndromes
• Secondary cystoid macular edema following a vascular occlusion

Treatment depends on the type and severity of the occlusion. Central retinal artery occlusion cases may call for ocular massage, anterior chamber paracentesis, or immediate referral for stroke-protocol evaluation, since CRAO and cerebral stroke share common causes. Branch retinal artery occlusion patients are often monitored and treated only if complications develop. Patients with diabetes face particular risk, as the effects of diabetes on retinal blood vessels can contribute to both arterial and venous blockages. In every case, managing the underlying vascular cause is a core part of the treatment plan.

What Should You Expect from Treatment?

• A dilated eye examination to evaluate the retina, optic nerve, and blood vessel integrity
• Diagnostic imaging with OCT and fluorescein angiography to map blood flow and measure tissue damage
• A detailed discussion of findings, including the type of occlusion and the degree of retinal involvement
• Coordination with your primary care physician or cardiologist if a systemic workup is needed
• A treatment plan that addresses both the retinal condition and any contributing cardiovascular or metabolic risk factors

What Is the Typical Treatment Timeline?

• Your first visit will include a full retinal evaluation with imaging and typically lasts 60 to 90 minutes
• For acute occlusions, same-day or next-day intervention may be recommended based on clinical findings
• Follow-up visits are generally scheduled within one to two weeks to monitor for retinal changes and detect early complications
• If anti-VEGF injections or laser therapy become part of your plan, ongoing appointments every four to eight weeks may be necessary for several months
• Long-term monitoring continues for six months to a year or more, since complications from an eye stroke can develop gradually over time
• Individual timelines vary based on the type of occlusion, extent of vision loss, and your overall cardiovascular health

What Should You Bring to Your First Visit?

• Insurance card and a valid photo ID
• A current list of all medications, including over-the-counter supplements and blood thinners
• Previous retinal imaging or eye exam records from another provider, if available
• A written list of current medical conditions, with particular attention to cardiovascular history, diabetes status, and any blood clotting disorders
• Any questions you have about your diagnosis, treatment options, or what to expect going forward

Your first appointment will include imaging studies and a one-on-one physician consultation. If you are experiencing sudden vision changes that could signal a retinal artery occlusion, let our scheduling team know when you call so we can prioritize your visit accordingly.

What Are Some Important California Retinal Care Resources?

The following resources provide information about retinal conditions, physician credentials, and vision health in California:

• The National Eye Institute publishes detailed guides on retinal diseases, available treatments, and federally funded vision research across the United States
• The CDC vision health initiative offers national data on eye disease prevalence, risk factors, and prevention strategies at the state and county level
• The Medical Board of California allows patients to verify physician licenses, board certifications, and any disciplinary actions before choosing a provider
