Stage 4 ROP is defined by which condition?

Stage 4 ROP (Retinopathy of Prematurity) is characterized by partial retinal detachment. In this stage, the abnormal blood vessels that develop in the retina may lead to a detachment of the retina from the underlying tissue, which can significantly affect vision. It's important to differentiate this stage from others, as earlier stages (such as stages 1, 2, and 3) may involve varying levels of abnormal blood vessel growth without retinal detachment.

A clear understanding of this progression is crucial for vision professionals because identifying and monitoring the stage of ROP can impact treatment decisions and outcomes. This knowledge allows for timely interventions to prevent further deterioration of vision.
