retinopathy of prematurity
An eye disease affecting premature infants, characterized by abnormal blood vessel development in the retina.
Full Definition
Retinopathy of prematurity (ROP) is a potentially blinding eye disease that affects premature infants, particularly those born before 31 weeks gestation or weighing less than 1,250 grams. The condition results from abnormal vascular development in the incompletely vascularized retina, often exacerbated by oxygen exposure and other factors. ROP is staged 1-5 based on severity, with stages 4-5 involving retinal detachment. Early detection through routine screening and timely intervention with laser therapy or anti-VEGF injections can prevent blindness. The condition may also be associated with long-term visual impairments including myopia and strabismus.
Usage
Usage note: ROP acceptable after first use. Always specify stage and zone when documenting findings.
