Vision Health

Vision is one of our chief senses, but millions of people have problems with their vision every year—and some of these problems can cause permanent vision loss of even blindness. Early detection of these most common eye diseases and conditions, especially those that are age-related, gives patients much higher chances of retaining their vision. As we age, the risk of developing certain age-related eye diseases and conditions rises—but many can be found early through screening, so the more aware you are, the better! The following are the most prevalent eye diseases and conditions:

Color Vision Problems as We Age

Posted by

Abnormal color vision increases significantly with aging and affects 50% or more of people in the oldest age groups, according to a study done at The Smith-Kettlewell Eye Research Institute in San Francisco and published in the journal Optometry and Vision Science.

Training Can Improve Vision

Posted by Sondra Forsyth Sondra Forsyth

With a little practice on a computer or tablet — 25 minutes a day, four days a week, for two months — our brains can actually learn to see better. That is the encouraging finding of research done at the University of California, Riverside and published in the journal Current Biology. Although the team did the training with baseball players at the university who had normal vision, the hope is that the same training, called perceptual learning, will help people with low vision due to cataracts, macular degeneration, or amblyopia.

Glaucoma & a Recently Discovered Eye Layer

Posted by

A layer in the human cornea recently discovered by researchers at The University of Nottingham in the UK turns out to play a vital role in the structure of the tissue that controls the flow of fluid from the eye. The findings could shed new light on glaucoma, a devastating disease caused by defective drainage of fluid from the eye and the world's second leading cause of blindness. The paper was published in the British Journal of Ophthalmology,

Exercise Could Help with Age-Related Macular Degeneration

Posted by Jane Farrell

Here’s an additional benefit of being active: Moderate aerobic exercise could help slow the progression of retinal degenerative diseases, including age-related macular degeneration (AMD). The results of the animal study were published in The Journal of Neuroscience. One of the leading causes of blindness in older people, AMD is caused by the death of light-sensing nerve cells in the retina called photoreceptors.

What You Must Know About Glaucoma

Posted by Sondra Forsyth Sondra Forsyth

By Sondra Forsyth In April of 2013, I went for my annual eye exam. I’ve worn glasses or contacts for distance correction ever since elementary school but over the years, other than the usual age-related need for “readers”, I’ve never had any vision problems. This time, though, I saw a look of concern flash across the optometrist’s face when she did the test for ocular pressure. “Is something wrong?” I asked.

Brain Hot Spots for Post-Stroke Vision Recovery

Posted by

Research done in Germany and published in the journal Restorative Neurology and Neuroscience suggests that vision restoration after a stroke depends mostly on activity of residual vision that is still left after the injury. The study showed that both local neuronal activity and activity in the immediate surrounding area influence the development of visual recovery "hot spots." The team maintains that this is evidence that recovery of vision is mediated by partially surviving neurons.
