At Bright Sight Eye Specialists, we provide exceptional eye care for patients in Randwick and the Eastern Suburbs of Sydney. Led by Dr Rahul Dubey, a renowned retinal surgeon and cataract specialist, we combine advanced technology with compassionate, personalised care. If you’re dealing with visual issues like blurred vision or eye bleeding, it’s essential to know about conditions like retinal vein occlusion and the treatment options available.

What is Retinal Vein Occlusion?

Retinal vein occlusion (RVO) is a serious eye condition where one of the veins carrying blood away from the retina becomes blocked, preventing proper blood flow. This blockage can deprive the retina of the oxygen and nutrients it needs to function correctly. There are two types of RVO:

• Central Retinal Vein Occlusion (CRVO):

  A blockage in the retina’s main vein.

• Branch Retinal Vein Occlusion (BRVO): A blockage in one of the smaller branch veins of the retina.

When the blood flow is disrupted, it can lead to fluid leakage, swelling, and even eye bleeding, resulting in visual blur and other vision problems. If left untreated, retinal vein occlusion can lead to serious complications such as macular oedema and neovascularisation, which can severely impact vision.

Symptoms of Retinal Vein Occlusion

Many patients may not show any noticeable symptoms initially, and fundoscopy — a detailed retinal examination — often detects the condition during routine checkups. However, some common symptoms include:

• Blurred vision or sudden visual blur

• Floaters — small shapes drifting in your field of vision

• Eye bleeding or redness

• Pain or pressure in the eye

• Partial or complete vision loss in severe cases

If you experience any of these symptoms, it’s essential to seek treatment from a specialist promptly to prevent bleeding in the eye.. Early intervention can prevent the condition from worsening and help preserve your vision.

Causes and Risk Factors of Retinal Vein Occlusion

Retinal vein occlusion typically occurs when the retinal veins are compressed, often at arteriovenous crossings where arteries and veins share connective tissue. As arteries harden due to atherosclerosis (hardening of the arteries), they can press on the adjacent veins, leading to turbulent blood flow and clot formation.

Key risk factors include:

• Uncontrolled high blood pressure

• Obesity or being overweight

• Cardiovascular disease

• Glaucoma

• Diabetes

• Blood clotting disorders (more common in younger patients)

• Smoking, which damages blood vessels and increases the risk of clot formation

Early diagnosis through fundoscopy and other diagnostic tools can help manage these risk factors and prevent further complications.

Visual Blur Treatment and Eye Bleeding Treatment

At Bright Sight Eye Specialists, our treatment for retinal vein occlusion focuses on managing the underlying risk factors and addressing retinal complications. Depending on the severity of the condition, treatment options include:

1. Intraocular Injections (Anti-VEGF Therapy)
Anti-VEGF drugs are designed to stop the growth of abnormal blood vessels and reduce fluid leakage in the retina. These include:

• Vabysmo

• Lucentis® (ranibizumab®)

• Eylea® (aflibercept®)

Clinical studies show that over 80% of patients achieve significant visual improvement with these treatments. Injections are administered after local anaesthetic eye drops, and injection to minimise discomfort. Regular follow-ups are necessary to monitor progress and adjust the treatment plan if needed.

2. Steroid Injections and Implants
Steroid treatments, including the Ozurdex implant, help manage macular oedema — a common cause of visual blur. These injections reduce inflammation and swelling in the retina, improving vision over time.

3. Laser Photocoagulation
This laser treatment reduces the risk of vision-threatening complications by sealing off leaking blood vessels. It is particularly effective in cases where abnormal blood vessels cause eye bleeding.

4. Comprehensive Eye Exams and Fundoscopy
Regular fundoscopy and comprehensive eye exams are crucial for detecting retinal vein occlusion early, especially for patients with high-risk factors. Early detection allows for timely intervention, reducing the likelihood of severe vision loss.

Lifestyle Changes and Preventive Measures

In addition to medical treatments, adopting a healthy lifestyle can significantly reduce the risk of retinal vein occlusion and other eye conditions. Consider the following preventive measures:

• Maintain healthy blood pressure and cholesterol levels

• Adopt a balanced diet rich in fruits, vegetables, and whole grains

• Exercise regularly to promote healthy blood circulation

• Quit smoking to protect your blood vessels

• Schedule regular eye checkups, including fundoscopy, especially if you have underlying health conditions
