IL-17A acts on Th17 cells to produce anti-inflammatory response

Dual role discovered for molecule involved in autoimmune eye disease

July 23, 2020

The inflammatory molecule interleukin-17A (IL-17A) triggers immune cells that in turn reduce IL-17A’s pro-inflammatory activity, according to a new NEI study.

Study points to potential new approach to treating neurodegenerative diseases like glaucoma and Alzheimer’s disease

July 20, 2020

Researchers have shown for the first time that when one optic nerve in the eye is damaged, as in glaucoma, the opposite optic nerve comes to the rescue by sharing its metabolic energy.

Study helps to settle debate on roles of REM and non-REM sleep in visual learning

July 20, 2020

A study by a team of Brown University researchers sheds new light on the complementary roles of REM and non-REM sleep in visual perceptual learning.

Combating drug resistance in age-related macular degeneration

July 16, 2020

Researchers have discovered a strategy that can potentially address a major challenge to the current treatment for choroidal neovascularization (CNV), an aggressive form of age-related macular degeneration.

Vision loss in children whose eyesight may be 20/20 requires new diagnostic and teaching strategies

July 14, 2020

Cerebral (cortical) visual impairment (CVI) is a condition that interferes with the ability of the brain to process information from the eyes, and it has become a leading cause of visual impairment in the U.S.

Study finds that special filters in glasses can help the color blind see colors better

July 13, 2020

A new study found that special patented glasses engineered with technically advanced spectral notch filters enhance color vision for those with the most common types of red-green color vision deficiency (“anomalous trichromacy”).

More than Meets the Eye

July 13, 2020

A new study led by researchers at Harvard Medical School and the VA Boston Healthcare System shows that face blindness may arise from deficits beyond visual perception and appears to involve glitches in retrieving various contextual cues from memory.
