Protect Your Sight
What You Need to Know About Vision Health
(firmenpresse) - MISSION, KS -- (Marketwire) -- 02/07/13 -- (Family Features) Everyone's vision changes as they age, but some changes could indicate a more serious problem. Age-related macular degeneration and glaucoma are two of the most common eye diseases in older Americans. As many as 11 million people in the United States have some form of macular degeneration, and more than 3 million have some form of glaucoma, according to the BrightFocus Foundation, a nonprofit organization dedicated to preserving brain and eye health. There may also be an association between untreated poor vision and cognitive impairment, which is another reason to take steps to protect your eyesight.
Age-related macular degeneration is an irreversible destruction of the central area of the eye's retina, known as the macula, which leads to loss of the sharp, fine-detail, straight-ahead vision required for activities like reading, driving, recognizing faces, and seeing the world in color. It's the leading cause of vision loss in Americans 60 years of age and older, and the second highest cause of irreversible blindness in the world.
Glaucoma is actually a group of eye disorders. They have few symptoms in the early stages, but eventually the optic nerve is damaged, leading to loss of side vision or complete blindness. Glaucoma is a leading cause of blindness among African Americans and Hispanics in the U.S. Between the ages of 45 and 64, glaucoma is fifteen times more likely to cause blindness in African Americans than in Caucasians. All people older than 60 are at a greater risk of developing glaucoma than people who are younger.

from an eye doctor.
Regular eye exams are crucial in maintaining eye health and catching any warning signs early. This is particularly important for certain forms of glaucoma, as those affected may not feel or see that anything is wrong until the disease has progressed to stages when vision loss occurs. Comprehensive exams should include these three tests:
Visual acuity: using an eye chart to test your sight at various distances.
Pupil dilation: widening the pupil with eye drops, allowing the doctor to see signs of disease.
Tonometry: tests the fluid pressure inside the eye.
If you or a loved one experiences any severe or persistent symptoms such as these that can be associated with macular degeneration or glaucoma, contact an eye doctor immediately:
Loss of vision
Sudden blurred or hazy vision
Blind spots or "holes" in your vision
Shadows over the center of your vision
Pain in or around the eye that may be accompanied by nausea or vomiting
Halos around lights at night
Painful or intense sensitivity to light
Distortion or waviness of vision, especially central vision
A loss of side vision or a feeling that you're looking through a tunnel
