Early light reduction for preventing retinopathy of prematurity in very low birth weight infants.

Retinopathy of prematurity (ROP) causes vision loss in many premature infants each year, despite the advances being made in treatment. In the search for ways to prevent the disease altogether, the exposure of the retina to bright ambient light following premature birth has been a natural hypothesis, since the premature infant normally would be in the dark in-utero environment. Several controlled studies have now addressed this theory.
