According to the National Eye Institute, age-related macular degeneration is a leading cause of vision loss for people aged 50 and older. For some people, AMD progresses slowly, with vision loss not occurring for a period of time. In other people, AMD progresses very quickly, leading to vision loss in either one or both of the eyes.
What causes AMD?
The macula is a small spot located in the center of the retina in the back of the eye. Made of millions of light-sensing cells, the macula is the most sensitive portion of the retina, crucial for providing sharp, central vision. If damage occurs to the macula, the retina will have difficulty converting light into electrical signals to the brain, making it difficult for the brain to translate everyday images.
What are the symptoms for AMD?
If the macula is damaged, someone’s center field of vision may begin to appear blurry, dark, or distorted. Over time, this blurred area can grow larger, leading someone to develop blank spots in his or her central vision. He or she may also find that everyday objects no longer appear as bright and sharp as they used to be. Even though AMD doesn’t lead to complete blindness, it can interfere with daily activities, such as distinguishing faces, reading, writing, or cooking.
What are the treatment options for AMD?
Currently, there is no treatment for age-related macular degeneration , however there are ways for someone to reduce his or her risk. An ophthalmologist can assess a patient’s risk of AMD by providing a comprehensive dilated eye exam each year. This can also help determine whether or not AMD is progressing. People who are at risk of AMD can lower their risk by exercising, avoiding smoking, and eating nutritious foods such as green, leafy vegetables and fish.
