Lab-Grown Retina Gives Gene Change Clue to Rare Childhood Eye Condition
A study using tiny retinas grown in a lab has revealed how subtle changes in a key growth-controlling protein can lead to a condition causing serious eye defects from birth.

AI Can Use a Photo of the Eye to Estimate Retinal Age, Flag Risk for Major Diseases
There may be some truth to the saying "the eyes are the window to the soul." Age-related changes are reflected in the retina, the light-sensitive tissue at the back of the eye. Recent research shows that a photo of the retina may also reveal potential risks for major diseases like diabetes.

Seeing Keratoconus Earlier with Light Polarization and AI
Keratoconus is a progressive eye disease that weakens and thins the cornea, the clear front surface of the eye. In its early, subclinical stage, the cornea can still appear normal on routine exams. Yet this is when accurate diagnosis matters most, especially when patients are being evaluated for refractive surgery.

How Sugar Fuels Sight: Glucose Metabolism Linked to Epigenetic and Gene Expression Changes in the Retina
National Eye Institute (NEI) scientists have found that the way the retina metabolizes glucose directly controls which genes get switched on and off in light-sensing photoreceptors.

Experiments Advance Efforts to Restore Vision with Transplanted Neurons
Researchers at Johns Hopkins Medicine say they have successfully demonstrated that disrupting an eye structure long suspected of blocking the growth and survival of transplanted nerve cells may help restore vision in people with optic nerve damage.

Low-dose Eye Drops can Manage Adult Myopia for 24 hours
Groundbreaking research from the University of Houston shows that a single low-dose atropine eye drop can produce daylong effects in managing myopia, or nearsightedness, which affects roughly one-third of U.S. adults.

Transplanted Neural Stem Cells Help Preserve Vision in Retinal Degeneration
Cedars-Sinai investigators working to optimize a cell-based treatment for retinitis pigmentosa have uncovered how transplanted neural stem cells interact with host retinal cells to preserve vision. The findings, published in Nature Communications, may guide future research toward strategies to treat degenerative eye disease.

Immune Cells Play Key Role in Regulating Eye Pressure Linked to Glaucoma, Research Reveals
When the eye's drainage system clogs, pressure builds up and causes damage. The pressure can lead to glaucoma and vision loss. New research, published in the journal Immunity, reveals that a specialized set of immune cells act as the cleanup crew, pointing to a promising new target for therapies to prevent a major cause of blindness.

Closing your Eyes Might not Help you Hear Better After all
Most people will close their eyes when trying to concentrate on a faint sound. Many of us have been told that keeping our eyes closed helps us hear better that it frees up our brains' processing abilities and increases our auditory sensitivity. However, that strategy may sometimes backfire, particularly in environments with a lot of loud background noise.
