Age-related macular degeneration (AMD) is a common eye condition that most often affects Canadians over the age of 50. It can change your central vision, the part you rely on to see faces clearly, read a good book, or drive your car. With help from our team at Total Focus Optometry, you can support your or your family member’s sight.
While statistics vary, AMD is a leading cause of vision changes among older adults in Canada. This condition affects the sharp, detailed vision you need for everyday activities, which is why regular eye care is so valuable as you age.
What Is Age-Related Macular Degeneration?
Your eye is often compared to a camera. Your macula, which is the part of the eye that age-related macular degeneration (AMD) affects, is the part that captures fine details right in the centre of the picture. Over time, it can make your straight-ahead vision appear blurry or distorted.
While this condition does not lead to complete darkness, it can make it harder to do the things you love. Tasks that require sharp focus, like recognizing a friend from across the street or working on a hobby, can become more challenging.
The Types of AMD
AMD usually appears in 1 of 2 forms—dry or wet. Dry AMD is the more common type and often progresses slowly as the macula naturally thins with age, leading to a gradual blurring of your central vision.
Wet AMD is less common, but its effects can appear more quickly. This type occurs when new blood vessels grow beneath the retina (the back of the eye) and leak fluid, which can distort your vision more rapidly.
Spot the Early Signs and Symptoms
In its early stages, the signs of AMD can be easy to miss. You might just feel like your vision is a little “off.” Watch out for these early signs that your eyesight might be changing:
- Straight lines (like a doorframe or telephone pole) appear wavy or bent
- Words on a page look blurry
- A dim or empty spot appears in the centre of your vision
- Colours seem less bright than they used to
One simple way to check your vision at home is by using a pattern of straight lines with a dot in the middle (sometimes called an Amsler grid). By looking at the grid 1 eye at a time, you can notice if any lines appear wavy, blurry, or are missing. This can be a helpful way to track changes between your regular appointments.
Who Is at Risk for AMD?
Certain factors can increase the likelihood of developing AMD. Your risk may be higher if you are over 50, as age is a primary factor. A family history of the condition can also play a role.
Your overall health is also connected to your eye health. Factors such as high blood pressure or a diet low in certain nutrients may increase your risk. Long-term exposure to sunlight without proper eye protection may also contribute.
Lifestyle choices can also influence your eye health. For example, smoking is a known risk factor that can increase your chances of developing AMD and other eye conditions.
Can You Slow Down Macular Degeneration?
There is currently no cure for AMD, but you can take steps to support your eye health and manage the condition. Regular check-ups with an eye doctor in South Edmonton can help monitor your vision for any changes.
Lifestyle Choices for Your Eye Health
Simple, consistent habits can help support your vision. A nutrient-rich diet can support your overall health, and in turn, your eyes. Things like leafy greens, colourful vegetables, and fish rich in omega-3s all support your macula’s health. You can also protect your eyes by wearing sunglasses that block UV rays whenever you are outdoors.
The Role of Regular Eye Exams
A comprehensive eye exam is a key part of preventative care for your vision. An eye doctor can detect the earliest signs of AMD, often before you notice any symptoms yourself. Early action can help preserve your sight.
What to Expect at an Exam
During an eye exam, our team uses tools to look at the overall health of your eyes. The eye doctor may use innovative imaging, like an optical coherence tomography (OCT) scan, to get a detailed cross-sectional picture of the back of your eye. This technology helps detect even tiny changes in the macula early.
