- What is "Macular Degeneration"?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: One of my friends thought her loss of vision was due to a
- developing cataract, but a visit to her doctor has revealed that the condition
- is one called "macular degeneration". She is now seeking to find out all
- about this condition that she can. I would like to help her so please discuss
- this disease in your column. Her paper doesn't have it.

- ANSWER: Macular degeneration is a visual disability marked by a progressive
- loss of central vision. It gets its name from the part of the eye that is
- affected--the macula--which is the small part of the retina responsible for
- sharp central vision. It sends images in the direct line of focus to the
- brain. Thus the macula functions differently from the rest of the retina,
- which is responsible for peripheral and night vision.
- In macular degeneration, the afflicted individual becomes unable to
- clearly distinguish objects and colors and loses the ability to see clearly at
- long distances or to do close-up work. This impairment involves a breakdown
- in the membrane which separates the macula from underlying blood vessels which
- nourish it. As a result, the macula becomes physically displaced, with an
- unrestorable loss of central vision. Severe eye injury, heredity, myopia
- (nearsightedness) and certain diseases such as diabetes are believed to be
- contributing factors, especially when young people are affected, but macular
- degeneration is generally associated with the aging process which alters the
- membrane slowly over time.
- Unfortunately, there are no perfect cures or treatments for most cases
- that exist. However, degeneration caused by infection or disease may be
- treatable if diagnosed early. In addition, laser treatment used to close off
- damaged blood vessels in the macular area have proven effective in some cases,
- and the use of magnifiers and high-intensity reading lamps provide many
- patients with an increased ability to read.
