What is Age-Related Macular Degeneration (AMD)?
AMD is a progressive eye disease that affects the center area of the retina known as the macula. The macula is responsible for focus and brightness, so as it breaks down, it can lead to blind spots, greyness and distortions in the center line of vision. While it does not typically cause total blindness, AMD is still the leading cause of low vision and severe and permanent vision loss in American 60 years or older. Currently, about 15 million people in the United States have some form of AMD, ranging from mild to more advanced.
What are the Symptoms of AMD?
Typically, AMD will go unnoticed by the affected individual because there are no signs until it progresses or begins to affect both eyes. Eventually, these symptoms may include:
- Worsening or less clear vision
- Dark, blurred vision in the center of the eye
These symptoms can impact a patient’s ability to drive, read, and do other everyday activities.
What Causes Age-Related Macular Degeneration
There are two forms of AMD – wet and dry – directly caused by different interactions in the eye. Dry AMD is caused by fat and protein deposits called drusen that build up in the macula. Wet AMD stems from the formation of new blood vessels that then leak into the macula and create scar tissue that break down vision.
As far as the risk factors that may cause AMD, there are many:
- High blood pressure
- Vitamin D deficiency
- Family history
- Light eye color
- Gender (the risk is higher for females than males)
- Race (Caucasians are more likely to develop AMD)
- UV rays
How is Age-Related Macular Degeneration Diagnosed?
Because of the nature of this condition to progress unknowingly, AMD must be swiftly detected by an eye doctor. he earlier you catch it, the better. Regular eye exams can allow your to catch changes in your vision and look for drusen that may be key indicators of the development of this condition.
Your eye doctor may also dilate your eye for a clearer look at the retina. If there is anything unusual, they may conduct an optical coherence tomography (OCT) test which will take 3D images of your retina for clearer diagnoses.
