Over 13 million babies are born preterm (at less than 37 weeks' gestation) every year worldwide, including 30,000 in Canada. A major eye complication of preterm birth is retinopathy of prematurity (ROP), an eye disorder where abnormal blood vessels grow in the retina, stemming from incomplete development of the vessels. It can potentially lead to vision loss or blindness. World Prematurity Day highlights the need for better healthcare for babies born early, as well as better support systems for the babies and their families; it also promotes research into the prevention of preterm birth and care of preemies to ensure positive long-term health outcomes.
