According to a recent study out of the Wilmer Eye Institute at Johns Hopkins University School of Medicine, nearly 50 percent of people (47.4 percent) of the 2,044 U.S. adults polled rated vision loss as the worst possible health outcome, surpassing such other conditions as loss of limb, memory, hearing, or speech. Top concerns among respondents were a diminishing quality of life ranked followed closely by loss of independence. [Read more…]
Glaucoma affects more than 60 million people worldwide, with three million cases of glaucoma in U.S. adults alone. And with no known cure, glaucoma remains the leading cause of irreversible vision loss. However, new research points to Vitamin B3 – also known as niacin or nicotinamide – as a potential way of preventing glaucoma, having been already proven effective as a treatment in mice. The findings were published in the journal Science. [Read more…]
When eye fluid, known as the aqueous humor, isn’t circulating properly, intraocular eye pressure (IOP) can increase. Normally, this fluid drains out of the eye through a mesh-like channel; however, if this channel is blocked, the fluid has nowhere to go, causing IOP to increase. [Read more…]
According to new research from the National Bureau of Economic Research, Americans over the age of 65 are living longer. Between 1992 and 2008, healthy life expectancy at age 65 increased by 1.8 years, and two treatments contributed: better cardiac care and cataract surgery. Those who opt for cataract surgery also experienced fewer falls, injuries, and disabilities.
“Older people who have eye surgery to remove cataracts and improve their vision also significantly reduce their risk of breaking a hip in a fall, […] those in their early 80s experiencing nearly 30 percent fewer hip fractures in the first year […],” explained author Roni Caryn Rabin, The New York Times.

The lens inside the eye is made up of water and proteins and works much like a camera lens, says Gretchyn Bailey, editor in chief of Optometry Times. The lens focuses “light onto the retina for clear vision” and also “adjusts the eye’s focus, letting us see things clearly both up close and far away.” However, when the proteins within the lense clump together, this obscures clear vision. “This is a cataract, and over time, it may grow larger and cloud more of the lens, making it harder to see,” says Bailey.
