Retinal vein occlusion
A retinal vein occlusion is a blockage in a vein carrying blood away from the retina. It can cause bleeding and swelling at the macula, affecting central vision.
A blocked retinal vein. This example shows a branch retinal vein occlusion, affecting one area of the retina. A central retinal vein occlusion can affect a wider area.

Dr Chen assesses the retina and scans to determine what treatment and monitoring are needed. Eye injections may be used for macular swelling; laser is appropriate in some circumstances.
About eye injectionsHow do I prepare for a retinal appointment?
Testing and examination take time, and most retinal appointments involve dilating drops.
The drops blur vision and increase light sensitivity for several hours. Plan around that practical reality: bring sunglasses, and do not drive straight after the appointment. Retinal scans and photographs are often taken so that changes can be measured over time.
What should I bring?
- Your referral and any previous scans
- Current glasses
- A list of medications, including blood thinners
- Someone to drive you home
Many retinal conditions are managed alongside your optometrist or GP. Findings and plans are communicated back so that everyone involved in your care is working from the same picture.
