Scientists discovered a light-dependent molecular pathway that regulates how blood vessels develop in the eye. The findings in Nature Cell Biology suggest it may be possible to use light therapy to help premature infants whose eyes are still developing avoid vision problems, according to researchers at Cincinnati Children's Hospital Medical Center.

(HealthDay)—A contact lens (CL)-based drug delivery system is effective for therapeutic delivery of the antihistamine ketotifen, according to a study published online March 19 in Cornea.
Like high blood pressure, glaucoma is a devious disease.
An unhealthy diet including high fat and cholesterol-enriched food can contribute to developing eye diseases which lead to a loss of vision, University of Southampton research has revealed.
Eating a calcium-rich diet or taking calcium supplements does not appear to increase the risk of age-related macular degeneration (AMD), according to the findings of a study by scientists at the National Eye Institute (NEI). AMD is a leading cause of vision loss and blindness among people age 65 and older in the United States. The study findings are published in JAMA Ophthalmology.
Cells of the retinal pigment epithelium (RPE) form unique patterns that can be used to track changes in this important layer of tissue in the back of the eye, researchers at the National Eye Institute (NEI) have found. Using a combination of adaptive optics imaging and a fluorescent dye, the researchers used the RPE patterns to track individual cells in healthy volunteers and people with retinal disease. The new finding could provide a way to study the progression and treatment of blinding diseases that affect the RPE. The study was published today in the journal JCI Insight.
An adhesive gel packed with light-activated chemicals can seal cuts or ulcers on the cornea —the clear surface of the eye—and then encourage the regeneration of corneal tissue, according to a preclinical study published online today in Science Advances. The new technology, named GelCORE (gel for corneal regeneration), could one day reduce the need for surgery to repair injuries to the cornea, including those that would today require corneal transplantation.
As artificial intelligence continues to evolve, diagnosing disease faster and potentially with greater accuracy than physicians, some have suggested that technology may soon replace tasks that physicians currently perform. But a new study from the Google AI research group shows that physicians and algorithms working together are more effective than either alone. It's one of the first studies to examine how AI can improve physicians' diagnostic accuracy. The new research will be published in the April edition of Ophthalmology, the journal of the American Academy of Ophthalmology.
It was surprisingly simple. University of California, Berkeley, scientists inserted a gene for a green-light receptor into the eyes of blind mice and, a month later, they were navigating around obstacles as easily as mice with no vision problems. They were able to see motion, brightness changes over a thousandfold range and fine detail on an iPad sufficient to distinguish letters.
Millions of Americans are progressively losing their sight as cells in their eyes deteriorate, but a new therapy developed by researchers at the University of California, Berkeley, could help prolong useful vision and delay total blindness.
Researchers at the University of New Hampshire have created a hydrogel that could one day be made into a contact lens to more effectively treat corneal melting, a condition that is a significant cause for blindness world-wide.
(HealthDay)—Patients with exfoliation syndrome (XFS) may be at increased risk for chronic obstructive pulmonary disease (COPD), according to a study published in the January-February issue of Ophthalmology Glaucoma.
A quick eye exam might one day allow eye doctors to check up on both your eyeglasses prescription and your brain health.
Diabetes is a debilitating health condition which is expected to reach epidemic proportions in the next 20 years. According to the World Health Organisation, 108m people around the world had diabetes in 1980; by 2014 that figure was 422m. Three years later in 2017, 425m people worldwide were living with the disease and this figure is expected to exceed a staggering 629m by 2045.
Researchers at the Lions Eye Institute (LEI) and The University of Western Australia have pioneered a study of the world's first and only laboratory model of a rare type of retinal disease, paving the way for new treatment pathways.
