Retinal implants that deliver longer pulses of electrical current may noticeably improve image sharpness for individuals who have lost their sight due to retinitis pigmentosa, according to a new study.

Researchers at Florida Atlantic University are the first to show that cells in close proximity to each other can sense when a cell is dying due to environmental stressors like UV light and smoke, and eat the cell before it becomes toxic.

As part of the National Robotics Initiative (NRI), the National Institutes of Health announced that it will fund the development of three innovative co-robots—robots that work cooperatively with people.

Johns Hopkins researchers have developed a method to efficiently turn human stem cells into retinal ganglion cells, the type of nerve cells located within the retina that transmit visual signals from the eye to the brain.

This National Diabetes Month, there is some good news for people with eye complications from diabetes.

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.

A chemical that could potentially be used in eye drops to reverse cataracts, the leading cause of blindness, has been identified by a team of scientists.

Because sound travels much more slowly than light, we can often see distant events before we hear them. That is why we can count the seconds between a lightning flash and its thunder to estimate their distance.

Gene therapy preserved vision in a study involving dogs with naturally occurring, late-stage retinitis pigmentosa, according to research funded by the National Eye Institute (NEI), part of the National Institutes of Health.

Researchers have used fruit flies and mice to make novel discoveries about sensory physiology at both cellular and molecular levels that are important for light processing.
