Programmable digital glasses for lazy eye work as well as eye patching, study shows, improving vision by about 2 lines on the reading chart after 3 months. First new effective lazy eye treatment in 50 years.
A clinical trial funded by the National Institutes of Health has found that the drug ranibizumab (Lucentis) is highly effective in treating proliferative diabetic retinopathy. The trial, conducted by the Diabetic Retinopathy Clinical Research Network (DRCR.net) compared Lucentis with a type of laser therapy called panretinal or scatter photocoagulation, which has remained the gold standard for proliferative diabetic retinopathy since the mid-1970s. The findings demonstrate the first major therapy advance in nearly 40 years.
RPB-supported researchers have made a significant discovery that might lead to the delay or prevention of the most common cause of blindness in the elderly: age-related macular degeneration (AMD). Patients who take the drug L-DOPA (for Parkinson Disease, Restless Legs or other movement disorders) are significantly less likely to develop AMD and, if they do, it is at a significantly later age.
“Blink and you’ll miss it” isn’t only for eyelids. The human brain also blinks, dropping a few frames of visual information here and there.
Those lapses of attention come fast — maybe just once every tenth of a second. But some people may be missing more than others, according to psychologists at the University of Wisconsin–Madison.
Listen to the latest breakthroughs in eye care from scientists presenting at the world’s largest ophthalmology conference, AAO 2015. Three ophthalmology researchers will discuss their cutting-edge work on topics ranging from using nanoparticles to treat blinding retinal diseases to eye drops that could slow nearsightedness in children.
The thickness of the cortex in a region of the brain that specializes in facial recognition can predict an individual's ability to recognize faces and other objects.

Researchers at Johns Hopkins and the University of Washington report new research that sheds light on how the retina sets its own biological rhythm using a novel light-sensitive pigment, called neuropsin, found in nerve cells at the back of the eye.
People with a genetic predisposition for age-related macular degeneration (AMD) significantly increased their odds of developing the blinding eye disorder if they had a history of heavy smoking and consistently did not exercise or eat enough fruits and vegetables, according to an observational study of women funded by the National Eye Institute, part of the National Institutes of Health.
The addition of a daily outdoor activity class at school for three years for children in Guangzhou, China, resulted in a reduction in the rate of myopia (nearsightedness, the ability to see close objects more clearly than distant objects), according to a study in the September 15 issue of JAMA.
Scientists at the University of California, San Diego School of Medicine have elucidated a genetic interaction that may prove key to the development and progression of glaucoma, a blinding neurodegenerative disease that affects tens of millions of people worldwide and is a leading cause of irreversible blindness.
A follow-up study has shown that these peripheral lesions, which are not detected by traditional eye imaging, correlate very closely with the loss of retinal blood flow called retinal “non-perfusion” caused by loss of small blood vessels or capillaries.
Following the 2014 Ebola outbreak in West Africa that took the lives of more than 11,200 people in the region, the National Eye Institute, part of the National Institutes of Health, has deployed a team of clinicians and technical experts to Monrovia, Liberia to investigate the long-term effects of Ebola on the eye.
Vision researchers in Boston have published the second paper of a study designed to determine if a driver who suffers from loss of central vision is able to detect pedestrians in a timely manner when driving. Central visual field loss, a scotoma or blind area in central vision, is found most commonly in patients with age-related macular degeneration (AMD). Patients with AMD may drive provided their visual acuity at least meets the requirements for a restricted license. However, the size and location of the blind area are usually not considered when making licensing decisions. The purpose of the study was to evaluate how much these blind areas delayed responses to pedestrian hazards in the safe environment of a driving simulator.
A new study has found that the occurrence of advanced forms of a diabetic eye disease remains low among children living with diabetes, regardless of how long they have had the disease or their ability to keep blood sugar levels controlled. Researchers are therefore recommending that most children with type 1 diabetes delay annual diabetic retinopathy screenings until age 15, or 5 years after their diabetes diagnosis, whichever occurs later. Their findings were published online today in Ophthalmology, the journal of the American Academy of Ophthalmology
Vision researchers at Columbia University Medical Center have discovered a gene that causes myopia, but only in people who spend a lot of time in childhood reading or doing other “nearwork.”
When we move our head, the whole visual world moves across our eyes. Yet we can still make out a bee buzzing by or a hawk flying overhead, thanks to unique cells in the eye called object motion sensors. A new study on mice helps explain how these cells do their job, and may bring scientists closer to understanding how complex circuits are formed throughout the nervous system. The study was funded by the National Institutes of Health, and was published online in Nature.
Women who are deficient in vitamin D and have a specific high-risk genotype are 6.7 times more likely to develop AMD than women with sufficient vitamin D status and no high risk genotype.
Investigators at the Joslin Diabetes Center now have shown that eyes with diabetic retinal lesions predominantly in peripheral areas of the retina that are seen in UWF images but not in traditional retinal photographs show surprisingly higher risks of progressing to advanced stages of vision-threatening diabetic retinopathy.
Do you have problems with dry eyes? If so, you're not alone—it's one of the most common reasons for patient visits to eye care professionals. Recent years have seen significant progress in management of patients with dry eyes, according to the September special issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.
By early childhood, the sight regions of a blind person’s brain respond to sound, especially spoken language, a Johns Hopkins University neuroscientist has found
The inflammatory eye disorder autoimmune uveitis occurs when a person’s immune system goes awry, attacking proteins in the eye. What spurs this response is a mystery, but now a National Eye Institute study on mice suggests that bacteria in the gut may provide a kind of training ground for immune cells to attack the eye.
