A recent report by the Pediatric Eye Disease Investigators Group (PEDIG) provides evidence that increasing patching from two to six hours a day is effective at treating persistent amblyopia. The research was funded by the National Eye Institute, a part of the National Institutes of Health.

Some of the most common vision disorders take their toll by damaging blood vessels near the retina. But it’s difficult for eye care professionals and researchers to see these vessels with standard techniques. NIH’s National Eye Institute is supporting the development of new methods to get deeper, more detailed views of the retinal vasculature.

November is National Diabetes Month. It's a good time to remember that people with diabetes are at risk for vision loss from diabetic eye disease. Anyone with diabetes should have a comprehensive dilated eye exam at least once a year.

Ten years after a transplant, a cornea from a 71-year-old donor is likely to remain as healthy as a cornea from a donor half that age, according to a study funded by the National Institutes of Health. Corneas from donors over age 71 perform slightly less well, but still remain healthy for the majority of transplant recipients after 10 years, the study found.

Small research labs provide an engine of discovery for new therapies. But developing a new drug or device requires expertise that is typically beyond the scope of a single lab. NEI has a program that helps diverse experts work together and move potential therapies into clinical trials.

Glaucoma is a stealthy disease. It can cause irreparable damage to the eyes before there is any vision loss. It also has been known since antiquity, but its cause is a mystery in most cases. Glaucoma Awareness Month is a good time to ask: Are researchers making progress toward solving this mystery?

For adults and children who undergo cataract surgery, implantation of an artificial lens is the standard of care. But a clinical trial suggests that for most infants, surgery followed by the use of contact lenses for several years—and an eventual lens implant—may be the better solution.

An inexpensive glaucoma drug, when added to a weight loss plan, can improve vision for women with idiopathic intracranial hypertension (IIH), according to a study funded by NEI. This disorder mostly affects young, overweight women. Vision loss and headaches are common symptoms.

A new study offers an explanation for how years of chronic sunlight exposure can increase the risk of cataract, a clouding of the eye lens that typically occurs with aging. The study firms up a link between the sun’s damaging rays and a process called oxidative stress.

In laboratory tests, researchers have used electrical stimulation of retinal cells to produce the same patterns of activity that occur when the retina sees a moving object. Although more work remains, this is a step toward restoring natural, high-fidelity vision to blind people.
