RVO: FAQs
Retinal vein occlusion (RVO) occurs when a vein draining blood from the retina becomes blocked, affecting retinal circulation and potentially causing vision loss.
It may involve the main retinal vein (CRVO), a branch vein (BRVO), or part of the retinal circulation (hemiretinal vein occlusion). Fluid accumulation in the macula (macular oedema) is a common reason for blurred vision.
Diagnosis involves retinal examination and imaging, including OCT scans, to guide treatment decisions.
Yes. RVO can be a serious condition because it affects the blood supply and drainage of the retina.
Severity depends on the location of the blockage and whether the macula is affected. Complications may include persistent swelling, abnormal blood vessel growth, bleeding, or increased eye pressure.
Prompt assessment helps identify the appropriate treatment.
RVO can cause permanent visual loss, particularly when there is significant retinal damage, reduced blood supply, or involvement of the macula.
The outcome depends on the type of occlusion, severity, duration of swelling, and how quickly treatment begins. Regular monitoring and appropriate treatment improve the chance of maintaining useful vision.

Treatment depends on the type of blockage and its effect on vision.
Options include anti-VEGF injections, steroid treatment, laser therapy in selected cases, and observation with regular monitoring when immediate treatment is not required.
Most patients find retinal injections are not painful or cause only mild discomfort.
The eye is numbed with anaesthetic drops before treatment. Some patients notice temporary irritation, redness, or a gritty sensation afterwards, which usually settles quickly.
The frequency varies between patients. Treatment usually begins with a series of injections, followed by a schedule based on retinal response and OCT findings.
Some patients require more frequent treatment initially, while others need fewer injections over time.
RVO can recur, although many patients do not experience another episode in the same eye.
Risk depends on factors such as blood pressure, diabetes, cholesterol levels, eye pressure, and overall vascular health. Managing these factors and attending regular eye reviews can reduce future risks.
Yes. Sudden blurred vision, distortion, or loss of vision should be assessed promptly by an eye specialist.
Early assessment helps identify the cause and allows appropriate treatment to be started when needed.
Patients with retinal vein occlusion can access specialist retinal care through Mr Kumar, an experienced Medical Retina Specialist providing assessment, imaging, injections, laser treatment, and ongoing monitoring.
If you experience sudden visual changes or have concerns about RVO, timely review by a retinal specialist is recommended.
