Retinal vein occlusion

A retinal vein occlusion occurs when a vein carrying blood away from the retina becomes blocked. This can cause sudden or gradual vision loss through swelling and bleeding in the retina.

A central retinal vein occlusion (CRVO) affects the main vein; a branch retinal vein occlusion (BRVO) affects a smaller branch. Treatment depends on the type and severity, and may include retinal imaging, injections to reduce macular swelling and monitoring for abnormal new blood vessels or glaucoma. Laser treatment may be needed.

Risk factors and monitoring

High blood pressure, diabetes, high cholesterol, smoking and glaucoma can contribute to retinal vein occlusion. Your GP and ophthalmologist can help manage these risks. Regular review is important even when no treatment is needed.

Age-related macular degeneration

Age-related macular degeneration (AMD) affects the macula, the part of the retina responsible for detailed central vision. We provide assessment, monitoring and treatment for dry and wet AMD.

Dry AMD usually progresses gradually. Wet AMD involves abnormal blood vessels that leak fluid or blood, and can cause rapid vision loss. Anti-VEGF injections are used to treat wet AMD. Follow-up and treatment intervals are tailored to your scans and response.

Monitoring, not smoking, a healthy diet and management of cardiovascular risk factors help protect your vision. Your ophthalmologist can advise whether an AREDS2 supplement is suitable for your stage of AMD.

Diabetic eye disease

Diabetes can damage retinal blood vessels, causing diabetic retinopathy and macular oedema. These changes may be present before you notice symptoms, so regular eye examinations are important.

We provide imaging, monitoring, laser therapy, injection treatments and surgery when needed. Macular oedema can occur at any stage of retinopathy and is assessed separately. Your ophthalmologist will discuss the treatment and follow-up appropriate for you.

Ocular inflammatory conditions

Inflammation inside the eye, known as uveitis, may cause pain, redness, light sensitivity, floaters or blurred vision. It can be associated with autoimmune disease, medications or infections.

Management involves identifying the cause and treating inflammation promptly with topical, injected or systemic medication to reduce the risk of permanent vision loss.

Changes in vision

Contact your eye specialist promptly if you notice new distortion or a change in central vision. Sudden vision loss, a curtain or shadow, or severe eye pain requires urgent assessment. Outside clinic hours, attend your nearest emergency department if urgent help is needed.
