Light Therapy Could Help Prevent Vision Problems in Premature Infants
CINCINNATI, April 2, 2019 — The discovery of a light-dependent molecular pathway that regulates how blood vessels develop in the eye could lead to the use of light therapy to help premature infants, whose eyes are still developing, avoid vision problems. Called the opsin 5-dopamine pathway, it helps ensure that blood-vessel development in the eye is appropriately balanced, but it can be thrown out of balance in premature babies. The study is a collaboration of research institutions in the United States and Czech Republic
