Blindness Due to Age-Related Macular Degeneration Should Not be Considered an Inevitability
Feb 6, 2014 - 10:29:14 AM
AMD, which affects an estimated 11 million Americans, is the deterioration of the eye's macula - the light-sensitive tissue lining the back of the eye that is responsible for central vision, the ability to see fine details clearly. AMD has two forms - wet and dry. While dry AMD leads to a gradual loss of vision, wet AMD leads to faster vision loss and is the most advanced form of the disease. Wet AMD is responsible for 80 to 90 percent of all AMD-related blindness. As AMD is not commonly detected in patients until they begin to suffer vision loss, it is critical for seniors to understand the importance of routine eye exams. The American Academy of Ophthalmology recommends that by age 65, seniors should get eye exams every one to two years, or as recommended by their ophthalmologist.
Years after Joan Nick, an 86-year-old retiree from Carmel, Calif. lost vision in her right eye in her 60s due to glaucoma, she was diagnosed with dry AMD in her left eye. Her ophthalmologist at the time advised her not to worry since the disease typically progresses slowly. But, during a routine eye exam, Nick was shocked to find she could not read an eye chart. Although she hadn't noticed any changes in her vision, her AMD had progressed from dry to wet. Nick immediately visited a retina specialist who began treatment that restored the vision lost to AMD.
"I am so thankful that this treatment has given me a second chance to enjoy the activities I love, such as reading and cooking," says Nick.
Rahul N. Khurana, M.D., Nick's ophthalmologist specializing in retina-related conditions and a clinical spokesperson for the American Academy of Ophthalmology, encourages seniors to learn from Nick's example of taking action to fight the progression of AMD. "Many older people develop AMD and other age-related eye diseases as part of the body's natural aging process, but seniors should not suffer in silence about their sight loss because they feel it's inevitable," said Dr. Khurana. "There is so much that we ophthalmologists can do these days to help seniors prevent, slow and treat AMD. It's important for seniors to know that people with AMD today have a much better chance of saving their vision than they did 10 years ago."
For individuals who have been diagnosed with dry AMD, nutrient supplements have been proven beneficial in lowering the risk of developing wet AMD. For those who have the wet form of AMD, treatments are available and include anti-VEGF injections that are administered directly into the eye, thermal laser therapy, or photodynamic therapy which involves a light-activated injected drug in combination with a low-power laser.
Seniors who are worried about AMD or other eye conditions, and have not had a recent eye exam or for whom cost is a concern, may qualify for EyeCare America, a public service program of the Foundation of the American Academy of Ophthalmology that offers eye exams and care at no out-of-pocket cost for eligible seniors age 65 and older.
