Age-Related Macular Degeneration (AMD)
Symptoms, causes, treatment, and when to see an optician
Overview
Age-related macular degeneration (AMD) is the leading cause of sight loss in the UK, affecting over 600,000 people. It damages the macula — the small central area of the retina responsible for sharp, detailed vision used for reading, recognising faces, and driving. AMD does not cause total blindness, but it can severely affect central vision and independence, particularly in its wet (neovascular) form.
Symptoms
- Distortion of straight lines — for example, door frames or text may appear wavy or bent
- A blurred or missing patch in the centre of your vision
- Difficulty reading, even with glasses
- Colours appearing less vivid than before
- Difficulty recognising faces
- Needing brighter light for close work
- Slow adjustment when moving between bright and dim environments
Causes & Risk Factors
- Ageing — the strongest risk factor; AMD is rare before age 55 and common after 75
- Smoking — the most significant modifiable risk factor, roughly tripling the risk
- Family history — having a close relative with AMD substantially increases your risk
- Ethnicity — AMD is more common in white European populations
- Cardiovascular risk factors including high blood pressure, high cholesterol, and obesity
- Prolonged exposure to UV light and blue light
- Diet low in antioxidants, leafy greens, and omega-3 fatty acids
Treatment Options
Dry AMD, which accounts for about 90% of cases, currently has no medical treatment. Management focuses on monitoring, lifestyle modifications, and nutritional supplementation. The AREDS2 formulation — a specific combination of vitamins C and E, zinc, copper, lutein, and zeaxanthin — has been shown to reduce the risk of progression to advanced AMD in some patients. Your ophthalmologist or optometrist can advise whether this supplement is appropriate for your stage of AMD.
Wet AMD, though less common, can cause rapid and severe vision loss if not treated promptly. The standard treatment in the UK is anti-VEGF injections (such as ranibizumab, aflibercept, or faricimab), which are given directly into the eye under local anaesthetic. These injections block the growth of abnormal, leaky blood vessels beneath the macula. Treatment is provided through hospital eye departments and is fully funded by the NHS. Most patients require a series of injections over months or years, with the frequency guided by regular OCT scans.
Low-vision rehabilitation services are available through the NHS and charities such as the Macular Society and RNIB. These services provide magnifying devices, adaptive technology, emotional support, and practical advice to help people with AMD maintain their independence and quality of life. If you notice any sudden changes in your central vision — particularly distortion or a dark patch — treat it as urgent and contact your optician or eye casualty department the same day.
Prevention Tips
- Stop smoking — it is the single most impactful thing you can do to reduce your risk of AMD
- Eat a diet rich in leafy green vegetables (spinach, kale), colourful fruit, and oily fish
- Maintain a healthy weight and stay physically active
- Wear sunglasses with UV protection in bright conditions
- Control blood pressure, cholesterol, and blood sugar levels
- Use an Amsler grid at home to monitor for early changes in your central vision
- Attend regular eye tests, especially after age 50, and request an OCT scan if available
When to See an Optician
Book an urgent eye test immediately if you notice distortion of straight lines, a dark or blurred patch in your central vision, or any sudden change — early detection of wet AMD is critical for effective treatment.
