Researchers have developed eye drops that extend vision in animal models of a group of inherited diseases that lead to progressive vision loss in humans, known as retinitis pigmentosa. Researchers at ...

A group of scientists restored vision in a monkey by using human stem cells to fix a hole in its retina. The research could open new doors for vision treatment in humans and other animals, too. A new ...

Imagine you're a red-tailed hawk, soaring through the sky. You scan the ground, looking for your next meal. You spot a squirrel hundreds of feet below you. Its coat helps it blend into the ground, but ...

Human vision relies on photoreceptor cells in the retina that react to visible light and trigger neurons in the optic nerve to send signals to the brain. Degradation of these photoreceptors is the ...

Vision is one of the most fascinating abilities in the animal kingdom. From birds that can spot prey miles away to sea creatures that see light we cannot even imagine, animals experience the world ...

Model of PEDF protein alongside the 17-mer and H105A peptides. Amino acid 105, which is changed from histidine in PEDF and the 17-mer peptide to alanine in the H105A peptide, is shown in green.

A new study suggests that never-seen-before stem cells in the human retina can restore vision in mice with a common eye disorder. But more work is needed to translate the treatment to people. When you ...

A protein in animals has the potential to reverse cataracts in humans without surgery, though more research is needed to know if it works, a new study finds. Researchers found a naturally occurring ...

Rebooting the Eye To test this theory, the team injected an anesthetic called tetrodotoxin into the lazy eye of lab animals ...
