What is a characteristic of ROP Stage II?

In Stage II of Retinopathy of Prematurity (ROP), one of the key characteristics is severe vascularization without detachment. In this stage, the abnormal blood vessels have proliferated and are significantly prominent, but the retina remains intact, meaning there is no detachment occurring at this point. This stage indicates a progression in the disease where the retinopathy is worsening in terms of the abnormal growth of blood vessels, yet the structure of the retina itself has not been compromised by detachment.

The other stages and characteristics mentioned reflect either more advanced conditions, such as partial or complete retinal detachment, or a return to normal retinal development which would not apply at this stage of ROP. Understanding these stages helps healthcare professionals in monitoring and managing ROP effectively, ensuring timely interventions when necessary.
