While macular degeneration can significantly affect central vision, total blindness is extremely rare.
This article explores the risks, statistics, and strategies for managing macular degeneration effectively, helping you understand what lies ahead and how to protect your vision.
How many patients with macular degeneration develop severe vision loss?
Macular degeneration primarily impacts the macula, the part of your retina responsible for central vision. This means you may lose the ability to see fine details, read, or drive, but peripheral vision often remains unaffected. In fact, complete blindness – where there is no perception of light – occurs in less than 1% of macular degeneration cases.
Outcomes for wet macular degeneration
When looking at the numbers, around 10-15% of people with AMD develop wet AMD, the more advanced and aggressive form of the condition. This variant can progress rapidly if left untreated, leading to significant vision loss. However, treatments like anti-VEGF injections have transformed outcomes, helping the majority of patients maintain functional vision.
Outcomes for dry macular degeneration
For dry AMD, which is far more common and accounts for 80-90% of cases, the progression is generally slower. Although it can cause substantial central vision loss over time, it rarely results in the level of impairment seen in untreated wet AMD.
Why early detection of macular degeneration is critical
Spotting the signs of macular degeneration early can make a significant difference in outcomes. Symptoms like blurry or distorted vision, difficulty recognising faces, or seeing dark spots in your central vision should prompt an immediate visit to your optometrist.
For wet AMD, timely treatment is vital, as this form of the disease can progress within weeks or months. Anti-VEGF injections are one of the most effective treatments for wet AMD. These injections target abnormal blood vessel growth in the eye, helping to stabilise vision in up to 90% of patients.

Around a third of those treated even see an improvement in their vision. Without intervention, however, wet AMD can cause severe vision loss, with approximately 20% of patients reaching this stage.
For dry AMD, while no cure currently exists, lifestyle changes and regular monitoring can slow its progression. Staying proactive about your eye health is one of the best ways to protect your vision over the long term.
How to live a full life with vision loss
If you’re living with macular degeneration and experiencing vision loss, you’re not alone. Many tools and resources are available to help you adapt and maintain your independence.
- Registering as sight impaired or severely sight impaired can open doors to benefits, including financial assistance, parking permits, and specialised healthcare services.
- Magnifiers, talking devices, and screen readers can make tasks like reading or using a computer easier.
- Mobile apps designed for visually impaired users are also widely available.
- Organisations such as the RNIB provide a wealth of support, from emotional counselling to practical aids.
Final notes
While being diagnosed with macular degeneration can be daunting, it’s important to focus on the facts. The risk of complete blindness is extremely low, and with today’s treatments and support systems, most people with AMD retain functional vision.
Staying proactive, seeking timely care, and adopting healthy habits are all steps you can take to protect your sight and maintain your quality of life.
Macular degeneration doesn’t have to define you or your future. With the right knowledge, tools, and support, you can navigate the challenges it brings and continue to enjoy the activities you love. Remember, you’re not alone—help is always available to guide you through this journey.
