Eye stroke, or retinal artery occlusion, is a serious condition affecting the retina, the light-sensitive layer at the back of the eye.

It can lead to sudden vision loss and requires immediate attention. Early diagnosis and treatment are crucial for preventing permanent damage and preserving visual function.

What are the Symptoms and Warning Signs of Eye Stroke?

Recognizing eye stroke symptoms early can lead to better outcomes. Symptoms usually occur suddenly and without pain. Immediate medical intervention is crucial for preserving eyesight and avoiding long-term vision loss.

Prompt recognition of signs like blurry vision, dimming, or sudden blindness can be the difference between full recovery and permanent damage.

Common Symptoms

• Sudden loss of vision in one eye
• Blurred or dimmed vision
• Visual field defects (e.g., shadow or blind spot)

Severe Symptoms

• Complete, painless vision loss
• Eye pain (rare)

What are the Different Types of Eye Stroke?

Eye strokes are mainly classified into two types based on the affected retinal arteries. Each type presents distinct risks and treatment needs. Understanding the type of stroke in the eye helps guide proper medical care. Knowing the difference between CRAO and BRAO can help patients and caregivers respond more effectively and understand the implications.

Central Retinal Artery Occlusion (CRAO)

A blockage in the main artery supplying the retina often causes sudden, profound vision loss.

Branch Retinal Artery Occlusion (BRAO)

A blockage in smaller retinal artery branches leads to partial vision loss, depending on the area affected.

What are the Common Causes and Risk Factors of Eye Stroke?

Several medical conditions and lifestyle factors can increase the risk of developing an eye stroke. Understanding the causes and risk factors is key to prevention and early intervention. Timely management of contributing health issues can dramatically reduce your risk of vision-threatening events.

Causes

• Atherosclerosis (plaque buildup in arteries)
• Embolism (clots from the heart or arteries)
• Inflammatory diseases like giant cell arteritis

Risk Factors

• High blood pressure
• Diabetes
• High cholesterol
• Smoking
• Cardiovascular disease

Physical Examination

Ophthalmologists examine the retina for signs of artery blockage or swelling.

Imaging Tests

• Optical Coherence Tomography (OCT) for retina cross-section imaging
• Fluorescein Angiography to observe retinal blood flow.

Blood Tests

Used to identify related conditions like high cholesterol or diabetes.

What are the Treatment Options for Eye Stroke?

Eye stroke treatment depends on the cause and type of blockage. Early intervention can reverse or reduce vision loss. Ongoing management is essential for preventing further complications. Medicover offers complete care, including medication, therapy, and surgical interventions prepared to individual patient needs.

Medication

• Clot-busting drugs (if given early)
• Anti-inflammatory medications if inflammation is present

Laser Therapy

It may help restore blood flow in the retina.

Hyperbaric Oxygen Therapy

Improves oxygen supply to damaged retinal tissue.

Surgery

In rare cases, procedures are used to remove blockages or relieve pressure.

Post-Treatment Care

• Follow-up visits to monitor retinal health
• Vision rehabilitation exercises
• Managing blood pressure, cholesterol, and diabetes
