Missing just one eye doctor appointment can result in vision loss in older adults with macular degeneration, a new study warns.

Age-related macular degeneration (AMD) is a leading cause of vision loss in the elderly, and these findings show the need for patients to keep all scheduled appointments with an ophthalmologist, the University of Pennsylvania School of Medicine researchers sa...

More than 2 billion people worldwide suffer vision problems that range from impairment to blindness, according to a new report from the World Health Organization (WHO).

And at least 1 billion of those people have problems such as short- and far-sightedness, glaucoma and cataracts -- all of which could have been prevented or have not been treated.

"Eye conditions and vision i...

Can a steady diet of junk food rob you of your vision?

A new case report suggests it's possible: After years of eating only potato chips, French fries, cold cuts and white bread, a 17-year-old British boy went blind.

Despite his bad eating habits, his body mass index, a standard measure of obesity, remained normal. But the lack of essential vitamins and minerals took its tol...

The virus that gave you chickenpox as a kid can rise again after decades of inactivity and inflict a painful, even blinding, eye infection in old age.

New research reveals that cases of eye-based "shingles" have tripled since 2004.

Exactly what is driving the increase remains unclear. What is clear, however, is that either of two vaccines could prevent many cases of shingles...

Researchers have long wondered why blind people seem to have a sharpened sense of hearing. Now a Seattle team has pinpointed specific brain adaptations that occur in folks without sight.

"There's this idea that blind people are good at auditory tasks, because they have to make their way in the world without visual information. We wanted to explore how this happens in the brain," said ...

Dangerous infections, blinding ulcers in the eyes: These are just some of the troubles that can come from wearing your contacts for too long.

One in four American adults (61 million people) has a significant physical or mental disability, the federal government reported Thursday. And these disabilities are more prevalent among women, people in the South, and those living in poverty.

Researchers at the U.S. Centers for Disease Control and Prevention analyzed 2016 data on six types of disability:

  • Mobility (ser...

A new study sheds light on how vision loss is linked to mental decline in seniors.

For the study, University of Miami researchers analyzed health data from more than 2,500 adults, aged 65 to 84, who were followed from about 1993 to 2001.

The investigators found that the rate of vision loss was associated with the rate of declining mental (cognitive) function. But mental fun...

These days, medical advances seem to be happening in the blink of an eye. Now, British scientists report they have created human corneas using 3D-printing technology.

The researchers said they hope this breakthrough will one day ensure an unlimited supply of corneas. Human corneas are now in short supply. Yet, there are 10 million people around the world who need them to prevent blind...

It's not just your skin that needs protection from ultraviolet rays, health experts warn.

UV rays from the sun can cause corneal sunburn (photokeratitis) and UV damage that has been linked to macular degeneration, cataracts, cancer and pterygium (a growth on the white part of the eye), according to Prevent Blindness, a nonprofit eye health and safety group.

The group has de...
