Retinopathy of Prematurity (ROP) is a disorder of the developing retinal vasculature that can occur in premature infants. It occurs when the normal growth of retinal blood vessels is interrupted, which can lead to abnormal neovascularization and retinal detachment if untreated. ROP is classified in stages based on the severity and location within the eye. Early mild stages may require only observation while more severe stages involving retinal detachment require laser treatment or surgery to prevent vision loss. Screening for ROP involves examination of the retina using specialized cameras to allow early detection and treatment.
5. The eye resembles a camera .The cornea and the crystalline lens act like a camera’s objective; they form an image on the retina, which is like the camera’s film. There the retina transforms the rays of light into nerve impulses that are carried by the optic nerve to the brain. It is in the brain that "seeing" occurs.
