Protecting the Vision That Matters Most as You Age
Age-related macular degeneration can gradually affect the part of your vision you rely on for reading, recognising faces, driving, and seeing fine detail. Some people first notice that straight lines appear distorted, words become harder to focus on, or central vision looks blurred or dimmer than before. These changes can develop slowly, which means AMD may not always be obvious in its early stages.
Because the condition affects the macula, the central part of the retina responsible for detailed vision, a comprehensive eye examination can help assess the extent of any retinal or macular changes. Depending on the findings, your eye specialist can then recommend the most appropriate approach to monitoring, managing, or providing retina macula treatment.
What Is AMD?
- Dry AMD (the more common type): This involves a slow thinning and breakdown of the macula, resulting in a gradual loss of vision.
- Wet AMD (the less common but more serious type): In this case, abnormal blood vessels develop beneath the retina, leaking fluid or blood, which can lead to quicker and more severe vision loss.
What Causes AMD?
- Family history of AMD
- Smoking
- High blood pressure or cardiovascular disease
- Diets low in antioxidants
- Long-term exposure to sunlight without UV protection
What Are the Symptoms?
- Blurred or fuzzy vision
- Difficulty reading or seeing fine detail
- Straight lines appear wavy or distorted.
- A dark or empty area in the centre of your vision
- Trouble seeing in dim lighting
How Is AMD Diagnosed?
- Visual acuity testing
- Dilated eye exam to check the retina
- OCT Angiography to detect thinning, fluid, or structural changes
- Retinal Dye Angiography (for wet AMD) to identify leaking blood vessels
Can AMD Be Treated?
- Lifestyle adjustments: Quitting smoking, wearing sunglasses, and adopting a diet rich in leafy greens and omega-3s
- Nutritional supplements: Based on the AREDS2 formula, for intermediate or advanced dry AMD
- Anti-VEGF injections: For wet AMD, these help control abnormal blood vessel growth and leakage
- Low-vision aids: Tools and strategies to support daily tasks if vision becomes significantly affected.
