February is Macular Degeneration Awareness month
An estimated 13 - 15 million Americans show evidence of
Age-Related Macular Degeneration (AMD), a progressive eye condition that can
destroy the “straight-ahead” vision required for activities such as reading or driving. To help
people better understand this disease, we’ve prepared a list of Frequently
Asked Questions about AMD.
Q: What causes AMD, and what are the risk factors?
A: The causes of AMD are
still unknown. One form of AMD (Dry) may be caused by aging and thinning of the
macular tissues, pigment deposits in the macula, or a combination of the two.
The other form of AMD (Wet), results when new blood vessels grow beneath the
retina and leak blood and fluid. This leakage causes retinal cells to die and
creates blind spots in central vision. Risk factors for AMD
include: Smoking, High Blood
Pressure, Obesity, and Family History of AMD. Also, Caucasians and females are
more prone to AMD.
Q: What are the symptoms
of AMD?
A: Early symptoms of AMD
included blurred vision or dark spots in the center of vision. The symptoms can
appear painlessly and gradually, making early detection and treatment
essential. Early-stage AMD can
be detected through a comprehensive eye exam that includes a visual acuity test
and dilated eye exam. If AMD is detected, further tests may be required.
Q: Can AMD be cured or treated?
A: There is no cure for
AMD at this time. There are, however, certain treatments that can slow or
minimize vision loss, and, in some cases, even improve vision. Some treatment options include vitamins or laser surgery.
