Understanding AMD
Understanding Age-Related Macular Degeneration
Age-related macular degeneration (AMD) is a leading cause of vision loss among older adults. It occurs when the central portion of the retina, known as the macula, deteriorates. Read on to learn more about AMD, its symptoms, types, and available treatments.
Symptoms to Watch For
Early stages of AMD often have no symptoms. As the condition progresses, you may notice blurred vision, difficulty reading, and dark or white spots in your central vision. In some cases, straight lines may appear wavy, and your color perception might change. Doctors use tests such as retinal exams, Amsler grid tests, and angiography to diagnose AMD.
Types of AMD
There are two main forms of AMD: dry and wet. Dry AMD is more common and progresses slowly, leading to gradual vision loss. Wet AMD is less common but more severe, causing rapid vision loss due to abnormal blood vessel growth under the retina.
Risk Factors
Several factors increase the risk of developing AMD, including age, smoking, high blood pressure, and high cholesterol. Genetics also play a role, and the condition is more prevalent in people with light skin and women.
Treatment Options
While there is no cure for AMD, treatments can slow its progression. For dry AMD, doctors may recommend AREDS2 supplements. Wet AMD treatments include anti-angiogenesis drugs and laser therapies to prevent further vision loss. Ongoing research aims to find better treatments and a potential cure for AMD.
Lifestyle Adjustments
Eat a balanced diet that's rich in antioxidants, omega-3 fatty acids, and leafy greens. Regular exercise, maintaining a healthy weight, and quitting smoking can also slow the progression.
Living with AMD
Vision aids and rehabilitation can improve quality of life for those with AMD. Special lenses, electronic devices, and better lighting can help maximize remaining vision.
Takeaways
Having age-related macular degeneration doesn't mean you'll lose your sight. Timely treatment and healthy lifestyle changes can help protect your vision. Even if you do lose some vision, low-vision aids and therapy can help you stay independent and doing the things you enjoy.
