Have Diabetes? Here's How to Save Your Sight

Managing your diabetes can be tough, but your eyes might thank you for it.

Diabetic retinopathy is a diabetes complication that damages the retina's blood vessels, often resulting in vision loss and blindness. The condition occurs in more than half of people with diabetes.

It affects nearly 8 million Americans and that number is expected to double by 2050, according to an Ameri...

Robotics Bring the White Cane Into the 21st Century

The "white cane" that many blind people rely on for navigating the world hasn't been upgraded in a century, but researchers are reporting progress on a "robo-cane" they hope will modernize the assistive device.

The prototype cane is equipped with a color 3D camera, sensors and an "on-board" computer designed to guide the user to a desired location and avoid any obstacles alon...

Man Blind for 40 Years Regains Some Sight Through Gene Therapy

Doctors for the first time have used a form of gene therapy to restore partial vision in a blind person, according to findings announced Monday.

The research team genetically altered retinal ganglion cells to become light-sensitive in a man whose vision was destroyed by retinitis pigmentosa, a genetic disorder that breaks down cells that absorb and convert light into brain signals.

Can a Drug Help Prevent Diabetic Vision Loss?

The overall eye health of people with diabetes benefits from preventive drug injections directly into the eyeball, but it's too soon to tell whether such treatment will better preserve their vision long-term, new clinical trial results show.

Regular injections of aflibercept (Eylea) caused a more than threefold reduction in blood vessel leakage inside the retina, and a more than twofold r...

Vision Problems Are On the Decline for American Seniors

Serious vision problems among older Americans have declined sharply, and the improvement has been greatest among women, folks over 85 and seniors who are Black or Hispanic, a nationwide study shows.

"The implications of a reduction in vision impairment are significant," said study first author ZhiDi Deng, a pharmacy student at the University of Toronto in Canada. "Vision problems are a ma...

Scientists Gain Insight Into Genetics of Glaucoma

Researchers have identified 44 new genetic variants associated with glaucoma, a leading cause of blindness. They say their findings could provide new targets to treat the common eye disease.

In their study, the international team compared the genes of more than 34,000 people with glaucoma and more than 349,000 people without the incurable eye condition.

In addition to pinpointing th...

New Hope for Better Treatments Against Macular Degeneration

A number of new treatments for age-related macular degeneration (AMD), a progressive eye disease, are under development. AMD is a leading cause of vision loss in older people.

About 11 million Americans have AMD, which affects part of the eye that allows you to see fine detail. There are two types: wet and dry. Wet AMD is treated with eye injections every month or two, and dry AMD with an...

Promising Steps Toward Retinal Cell Transplants to Fight Blindness

A promising step toward using retinal cell transplants to treat blindness is reported in a new study.

Adult retinal stem cells from deceased human donors survived when they were transplanted into the eyes of non-human primates, according to the researchers.

The cells were taken from the retinal pigment epithelium (RPE). It is a layer of cells that supports and nourishes the retina, ...

COVID Tied to Rare But Severe Eye Infection

A rare, sight-stealing infection might be triggered by COVID-19, a new study suggests.

In the space of two months, three patients suffering from COVID-19 in one New York health system developed keratitis, an inflammation of the cornea, which then led to a sight-threatening infection of the tissues or fluids inside the eyeball called endophthalmitis.

"I see things like this, but very...

Parkinson's Drug Eyed as Treatment for Severe Macular Degeneration

A drug long used to treat Parkinson's disease may benefit patients with a severe form of age-related macular degeneration (AMD), a small clinical trial suggests.

One of the leading causes of vision loss in older people is a condition called dry macular degeneration. More than 15% of Americans over age 70 have AMD, and 10% to 15% of those cases go on to develop the more sev...

Have Diabetes? Don't Lose Sight of Danger to Your Eyes

Diabetes can wreak havoc on many parts of the body, including the eyes, but people with diabetes aren't doomed to have vision problems.

With good blood sugar management and regular eye exams, many eye conditions can be prevented or treated, experts say.

Patricia Welter, a Pilates studio owner from Palm Harbor, Fla., wishes she'd known more about preventing eye problems rel...

With Macular Degeneration, 1 Missed Visit to Eye Doc Can Mean Vision Loss

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...

Vision Problems Strike More Than 2 Billion Globally

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...

Teen's Fussy 'Junk Food' Diet Leaves Him Blind

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...

Potentially Blinding Shingles of the Eye  on the Rise

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...

Brain Sharpens the Hearing of the Blind, Study Finds

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 ...
