What is AMD & Why It Matters

Age-related macular degeneration (AMD) is the leading cause of serious vision loss in people over 50. It affects the macula—the central part of your retina that controls sharp, detailed vision for reading, recognising faces, and driving. At Paterson Burn, we understand how AMD impacts daily life, but with early detection and proper care, many people continue living full, active lives.

There are two main types: dry AMD, which develops slowly and causes gradual central vision blurring, and wet AMD, which is less common but more aggressive due to abnormal blood vessel growth beneath the retina. Treatments are available that can slow progression and protect vision.

Early Signs & Monitoring

AMD often starts without obvious symptoms, so regular eye exams are vital. Early warning signs include blurred or fuzzy central vision, wavy or bent lines (like door frames or text), dark spots, difficulty adjusting to light changes, and trouble recognising faces. Spotting these early can make all the difference.

If you’re over 50 or have risk factors, annual comprehensive eye exams with advanced imaging can detect AMD before symptoms appear. For those diagnosed, regular monitoring helps catch progression early so treatments can be adjusted promptly.

Risks & Prevention

Age and family history are the biggest uncontrollable risk factors. Your risk rises significantly after 50 and if close relatives have AMD. But lifestyle choices also play a huge role: smoking greatly increases risk, as does a poor diet low in antioxidants. UV exposure and poor cardiovascular health can also contribute.

You can protect your eyes by quitting smoking, eating a nutrient-rich diet full of leafy greens, colourful fruits, and omega-3 fish, wearing quality UV-blocking sunglasses, staying active, and managing your overall health. These steps can lower your risk and help slow AMD progression.

Treatments & Support

While there’s no cure for dry AMD, specific nutritional supplements (AREDS2 vitamins) can slow its progress in some cases. For wet AMD, anti-VEGF eye injections have transformed treatment, reducing abnormal blood vessel growth and often improving vision. Most patients find these injections manageable.

Low vision aids like magnifiers, special glasses, and helpful apps can also support your independence and quality of life, making the most of your remaining vision.

Take Control of Your Vision

Managing AMD is a team effort. Regular check-ups, early detection, and a healthy lifestyle form the best defense. At Paterson Burn, we use the latest technology to monitor your eye health closely and tailor care to your needs.

Remember, an AMD diagnosis doesn't mean losing your sight. With the right care and habits, you can protect your vision and keep enjoying the things that matter most.
