Macular Degeneration

Macular Degeneration is one of the leading causes of vision loss in our country . It is a progressive disease that affects the macula, the center part of the retina (the back of the eye).
The light-sensitive retinal tissue controls how you see images: as images focus on the retina they are converted into electrical impulses that travel to the brain via the optic nerve. If there is damage or deterioration of the macula, your central vision will be disrupted.
Central vision is vital to perform common daily tasks such as reading, driving, recognizing faces and seeing fine details.
Many older people develop macular degeneration as part of the natural aging process. There are different kinds of macular problems, but the most common is Age-related Macular Degeneration (AMD). This disease is most common in people over 60 but can appear as early as age 40. If you are over age 60, routine eye exams can diagnose early signs of this degenerative eye disease.

Macular degeneration affects central vision, but not typical peripheral vision. In the early stages, you may not have any outward symptoms. As the disease progresses, you may experience:     

• Dark areas
• Blurriness
• Distortion (typically straight lines or objects appear wavy or crooked)
• Permanent loss of central vision

Accounts for 90% of all cases and progresses slowly.  It is caused by the build-up of yellow drusen deposits under the macula that causes the macula to thin and dry out.

This is a more serious form that causes severe, rapid vision loss. It occurs when abnormal blood vessels grow under the macula. If they leak blood or fluid, this will cause the macula to become distorted.

Scientists do not know the exact cause of macular degeneration and why some people develop this disease. Heredity, malnutrition, race, smoking and UV light exposure may play a role in increasing your risk for macular degeneration. It makes sense to follow a healthy lifestyle to help protect your vision:

• • Wear UV protection sunglasses when outdoors
  • Eat a healthy diet
  • Stop smoking

If you are experiencing any central vision problems, don’t wait until your vision is permanently lost.
