Macular Degeneration: Preserving Your Central Vision
Age-related Macular Degeneration (AMD) is a progressive condition that affects the macula, the small, central part of the retina responsible for sharp, detailed, straight-ahead vision (like reading, recognising faces, and driving). While AMD rarely leads to complete blindness, it is the most common cause of vision loss in older Australians.
We are committed to early detection and lifestyle management to slow the progression of this condition and help you maintain your quality of life.
Understanding the Two Types
AMD is classified into two main forms:
- Dry AMD: The most common form, caused by the gradual breakdown of the light-sensitive cells in the macula. It progresses slowly and causes gradual central vision loss.
- Wet AMD: A less common, but more serious form, where abnormal blood vessels grow under the macula, leaking fluid and blood. This causes rapid and severe distortion or loss of central vision.
Detection and Management
Because visual symptoms can be subtle in the early stages, we rely on advanced diagnostic technology for precise monitoring:
- Optical Coherence Tomography (OCT): This sophisticated scanner provides a cross-sectional view of the retina, allowing us to see and measure changes beneath the macula (like the presence of drusen or fluid) years before they impact your sight.
- Digital Retinal Photography: Used to capture high-resolution images of your macula to track changes over time.
Our management approach focuses on prevention and slowing progression: - Lifestyle and Diet Advice: Advice on smoking cessation, UV protection (sunglasses), and nutritional changes (e.g., green leafy vegetables).
- AREDS 2 Supplementation: Guiding you on the correct scientifically proven supplements that can slow the progression of intermediate Dry AMD.
- Urgent Referral: Immediate referral to a retinal specialist Ophthalmologist for potentially sight-saving treatment (like injections) if signs of the aggressive Wet AMD are detected.
Are You at Risk?
Age, family history, and smoking are the primary risk factors. Proactive screening is vital.
