Question
What causes retinopathy of premature babies?
Answer
Retinopathy of Premature Babies: The retina of premature babies is not fully developed. In a hyperoxic environment, the retinal blood vessels constrict and become blocked, leading to regional ischemia and hypoxia. This triggers abnormal proliferation of retinal blood vessels, causing a series of changes such as exudation, hemorrhage, and organization.
