Retinopathy of Prematurity (ROP) is due to an abnormal growth of blood vessels in the baby's eye. It is most common in babies who are very premature. In the baby’s development, blood vessels grow from the back of the eye out towards the edges. This process is completed just a few weeks before the normal time of delivery. In premature babies, this process is not complete. If blood vessel grows normally, the baby does not develop ROP. If the vessels grow and branch abnormally, the baby has ROP
