How to prevent cataracts
There are some simple things you can do to lower your risk and potentially slow or delay the development of cataracts later in life.
Age-related macular degeneration (AMD) is a leading cause of vision loss in older people. It’s an eye disease that can begin in a person’s 40s or 50s with distorted vision. The condition tends to worsen over time and becomes more noticeable in a person’s 60s or 70s. It currently affects about 11 million people in the United States.
This condition results from a combination of environmental and genetic causes. Age is the most important factor, since the risks increase as a person gets older. Smoking is also a risk factor.
People are more likely to develop AMD if they have a family history of this disease. Being Caucasian also raises your risk.
There are two types of AMD: wet and dry. Dry AMD is much more common and progresses more slowly. It typically affects both eyes, but vision loss can occur in one eye before the other. Dry AMD causes thinning of the macula. This causes blurred vision.
Wet AMD results from an abnormal growth of blood vessels that form under the macula. The blood vessels leak blood and fluid into the eye and cause blind spots. Wet AMD can progress very quickly. In some cases, dry AMD can turn into wet AMD.
AMD doesn’t lead to complete blindness. However, these symptoms can occur over time:
Ophthalmologists check for AMD with a dilated eye exam. They’ll put drops in your eye to dilate your pupils so they can check for AMD. This exam is simple and painless.
You may also use a special chart called an Amsler grid. You can use this at home to check your vision.
There’s no treatment for early AMD. Your eye doctor will recommend regular eye exams to keep track of your vision. If you smoke, you should quit.
For intermediate or late AMD, special dietary supplements may stop it from getting worse. If you have wet macular degeneration, there are treatments that may help further vision loss. These treatments include medicines that the doctor injects into your eye and laser treatment called photodynamic therapy.
At The Ohio State University Havener Eye Institute, we use state-of-the-art treatments with personalized eye care for each patient. Our retinal specialists have been trained at world-renowned institutions across the country, making our institute one of the top eye-care facilities in the nation.
The Robinson Advanced Imaging Center provides our patients access to the most advanced ophthalmic imaging available. Imaging is critical in monitoring the progression and treatment of AMD. At the Ohio State Wexner Medical Center, we’re also passionate about leading the way in research and innovation. We’re proud to support the Ohio State Wexner Medical Center's very own Katelyn Swindle-Reilly, PhD, and Matthew Ohr, MD, in their unique technology that allows for extended release of AMD drug treatment, thus allowing for less frequent drug administration.
