Macular degeneration symptoms and treatment
Early macular degeneration symptoms include problems seeing details such as small print when reading, with your central vision becoming blurry.
Also called age-related macular degeneration (AMD), there are two types; dry and wet. Dry AMD symptoms progress slowly, and there's no treatment available, but you can get support to help you deal with changes to your vision. Wet AMD symptoms can develop rapidly, but treatment can stop its progression and prevent further damage to your sight.
If you have any concerns about your sight or notice possible signs of AMD, see your optician or GP for advice.
Macular degeneration symptoms
Macular degeneration is an eye disease that affects the macula, part of the retina at the back of the eye. It's not painful, but it blurs or distorts the central vision we use to look straight at things when reading or watching television.
- Straight lines appearing wavy or with bumps in them
- Being more sensitive to bright light
- Noticing your sight isn’t as clear as it was before
- Having a dark patch or blind spot in your vision
- Objects ahead seeming smaller or even appearing to move or disappear
- Colours appearing washed out
Dry macular degeneration symptoms
The dry form of AMD tends to develop gradually over months and years. It can sometimes be detected during an eye test before you notice any symptoms. If you do experience changes to your sight, see your optician for an eye test.
In the later stages of AMD, it’s possible to experience visual hallucinations as a symptom if you have significant sight loss. This can understandably feel scary but is how the brain naturally adjusts to a substantial loss of vision.
Wet macular degeneration symptoms
Wet AMD can develop very quickly, in a matter of days or weeks. It’s essential to see your optician or specialist if you notice a sudden change in your sight, particularly if you already have dry AMD.
Although the conditions are called ‘dry’ and ‘wet’, these names don’t refer to the kind of symptoms you’ll experience. Wet AMD describes internal changes to the eye (the growth of blood vessels behind the macula) and doesn’t mean you'll experience tearing or watery eyes.

Macular degeneration symptoms test and diagnosis
See an optician if you notice problems that could be the early signs of macular degeneration. These include difficulty seeing details, for example, reading small print or if straight lines such as wall tiles start to look wavy. Minor changes to your vision can be hard to notice, so tools like an Amsler grid can help you check if your sight is distorted. The Amsler grid is like a piece of graph paper with straight vertical and horizontal lines. By looking at it with each eye, in turn, you can tell whether the lines look distorted or wavy.
An AMD test will start with your optician looking closely at the back of your eye to check for signs of ‘drusen’ (yellow dots) on the retina. These can occur as a normal part of ageing but can also be a sign of AMD. They may use an optical coherence tomography (OCT) scan to take detailed images of the back of the eye. This is a painless, non-invasive test.
If you have wet AMD your optician will refer you urgently to a hospital eye clinic for treatment. If they suspect dry AMD but need confirmation of your diagnosis, they may also refer you to a hospital eye clinic, although less urgently.
Eye exams and macular degeneration
If you have a family history of an eye condition such as AMD, make sure you mention this to your GP, eye doctor or optician. They may recommend you have further tests or more frequent eye exams to help spot any early symptoms.
If your optician thinks you have AMD, they may refer you to an ophthalmologist for confirmation and specialist support. They may even put you in touch with a dedicated AMD service.
Preventing macular degeneration
Age is the leading risk factor for AMD. The condition usually first develops in people in their 50s and 60s (Source: NHS). As women tend to live longer, it’s more common to see AMD in women than men.
While you can't necessarily prevent AMD, you can do something about lifestyle risk factors. Evidence strongly suggests that stopping smoking is a positive step to reduce the risk of developing AMD (Source: British Journal of Ophthalmology). Having an active lifestyle and a healthy diet rich in antioxidants is good for your eye health as well as your overall wellbeing.
