A two-year clinical trial that compared three drugs for diabetic macular edema (DME) found that gains in vision were greater for participants receiving the drug Eylea (aflibercept) than for those receiving Avastin (bevacizumab).

Our eyes are especially demanding when it comes to energy: Along with our brain, they require a substantial amount of power to keep them functioning and healthy.

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.

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.

Researchers at Johns Hopkins and the University of Washington report new research that sheds light on how the retina sets its own biological rhythm using a novel light-sensitive pigment, called neuropsin, found in nerve cells at the back of the eye.

When we move our head, the whole visual world moves across our eyes. Yet we can still make out a bee buzzing by or a hawk flying overhead, thanks to unique cells in the eye called object motion sensors.

Scientists at Washington University School of Medicine in St. Louis have identified a pathway that leads to the formation of atypical blood vessels that can cause blindness in people with age-related macular degeneration.

Spider-like cells inside the brain, spinal cord and eye hunt for invaders, capturing and then devouring them. These cells, called microglia, often play a beneficial role by helping to clear trash and protect the central nervous system against infection.

Researchers at Washington University School of Medicine in St. Louis have identified a neural circuit in the retina that enable the eye to detect movement.

New research, published online May 7 in the journal Neuron, describes how axons of specialized nerve cells find their way through the brain’s maze of neurons to make the right connection.
