Have you been diagnosed with macular edema?
Macular edema is a swelling in the central retina (macula) caused by fluid leakage or inflammation. It can lead to blurred or distorted vision and may develop gradually or come on more suddenly. Most cases are linked to other conditions like diabetes or retinal vein occlusion, and while not always urgent, rapid treatment is important when vision changes quickly.
What causes macular edema?
Cystoid macular edema occurs when fluid builds up in cyst-like spaces in the macula. This part of your retina is responsible for sharp, central vision, so swelling here can affect reading, driving, and facial recognition. It often results from:
- Diabetic retinopathy
- Retinal vein occlusion
- Eye surgery (e.g. cataract)
- Inflammatory eye conditions (e.g. uveitis)
- Certain medications
It is not always sight-threatening, timely macular edema treatment may be needed to protect vision, especially when symptoms progress quickly.
Common symptoms of macular edema
You may notice:
Blurred or distorted central vision
Difficulty reading or focusing
Colours appearing faded or washed out
A central shadow or blind spot
You should seek medical advice if symptoms appear suddenly or worsen rapidly.
How we diagnose macular edema
The first step in treating macular edema involves a thorough eye examination and retinal imaging. At our central London clinic, you’ll be seen by Professor Tom Williamson, one of the UK’s leading retinal surgeons. You’ll have time to explain your symptoms, ask questions, and receive a clear plan for next steps.
At your appointment, Professor Williamson will carry out:
- Optical Coherence Tomography (OCT): A detailed scan showing fluid build-up in the retina
- Fluorescein angiography: Used in some cases to map blood flow in retinal vessels
- Clinical eye exam: To assess visual function and rule out other causes
Professor Williamson takes a calm, unhurried approach, explaining everything clearly so you understand what’s going on and what can be done.
Tailored treatment for macular edema
After reviewing your test results and examining your eyes, Professor Williamson will recommend the most effective macular edema treatment for your case.
Intravitreal injections
Anti-VEGF injections block the chemical signals that trigger abnormal blood vessel growth and leakage. By reducing leakage and swelling, they can improve or stabilise vision.

Anti-inflammatory drops
Particularly for macular edema linked to inflammation or following cataract surgery. These steroid drops reduce swelling and are prescribed for several weeks, with follow-up to monitor recovery. Professor Williamson will guide you through the best option for your specific case.
Ongoing care and monitoring
Macular oedema is often a long-term condition that requires regular management. Under the care of Professor Williamson, you’ll have:
- Ongoing monitoring with OCT scans
- Repeat injections or treatments as needed
- Coordination with your GP or diabetes specialist where appropriate
We provide consistent care throughout. Professor Williamson follows each case closely, adapting your treatment plan as needed and staying available for any concerns.
