Even though Marlene Klein was having trouble recognizing familiar faces and began to mistake her fingers for carrots as she chopped vegetables, she had no idea she was slowly losing her vision to a leading cause of blindness, age-related macular degeneration (AMD). That's because her brain was compensating for the developing blind spots in her vision. Marlene is not alone. According to a recent Harris Poll survey, most Americans are unaware that people do not always experience symptoms before losing vision to eye disease. During February, the American Academy of Ophthalmology is urging people to protect themselves from vision loss from AMD by getting a baseline eye exam by age 40.
More than 2 million Americans are living with the most advanced forms of AMD, a number that is expected to reach 4.4 million by 2050. It is the leading cause of blindness among white Americans over 40, and it's a leading cause of irreversible vision loss throughout the world.
AMD happens when part of the retina called the macula is damaged. It's the part of the eye that delivers sharp, central vision needed to see objects straight ahead. Over time, the loss of central vision can interfere with everyday activities, such as the ability to drive, read, and see faces clearly.
Because AMD often has no early warning signs, getting regular comprehensive eye exams from an ophthalmologist is critical. Academy guidelines state that adults with no signs or risk factors for eye disease get a baseline eye disease screening at age 40 -; the time when early signs of disease and changes in vision may start to occur. From age 40 to 54, get your eyes examined every 2 to 4 years; from 55 to 64, every 1 to 3 years. By age 65, get an exam every one to two years, even in the absence of symptoms or eye problems. If you have risk factors for eye disease, you will need to be examined more frequently.
Ophthalmologists – physicians who specialize in medical and surgical eye care – have more tools than ever before to diagnose AMD earlier, and to treat it better. But these advances cannot help patients whose disease is undiagnosed, or patients who are unaware of the seriousness of their disease.
People's lack of understanding about AMD is a real danger to public health. As the number of people with AMD is expected to explode in the coming years, it's more important than ever that we prioritize eye health and have our eyes examined regularly." Rahul N.
