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.

Why Arthritis in Children Can Threaten Eyesight
Arthritis is often associated with older age, but it also affects children. One of the most common forms is juvenile idiopathic arthritis (JIA), an inflammatory condition that causes persistent joint swelling and pain.

What is `Eye Stroke` and Why has it Been Linked to Weight Loss Injections?
The phrase "eye stroke" has recently appeared in news reports about a very rare side effect of weight-loss injections. It's not a formal medical diagnosis, but a shorthand used to describe a condition in which reduced blood flow damages the optic nerve and causes sudden vision loss.

What`s the Link Between Tattoos and Vision Loss? Two Optometrists Explain
Getting a tattoo can be a thrilling, albeit painful, experience. About one-third of Australians have a tattoo, with many getting inked as a rite of passage. However, a small but increasing number of Australians are being diagnosed with a rare tattoo-related eye condition. It's known as tattoo-associated uveitis and can cause permanent vision loss.

A new robotic system could perform delicate eye surgery
Retinal vein occlusion (RVO) is a severe disease that occurs when a vein in the light-sensitive layer at the back of the eye (i.e., the retina) becomes blocked, which results in a loss of vision. There are currently a few medical interventions that address RVO, including the periodic injection of medications that block the abnormal growth of blood vessels or of steroids, which reduce swelling and inflammation.

Retina-on-a-chip offers promising perspectives for rare eye diseases
Researchers at the University of Twente and Radboudumc are developing a promising new model to enhance understanding of the human retina. They are developing a retina-on-a-chip, in which the three main layers of the retina will eventually be combined. The first two layers have now been successfully integrated, and work on the third is underway.

Study Reveals Potential Therapeutic Target for Treating Glaucoma
Researchers have identified a metabolically sensitive cell subtype in the eye's drainage system which shows early signs of dysfunction in a genetic mouse model of glaucoma.
