What occurs in Stage 3 ROP?

In Stage 3 Retinopathy of Prematurity (ROP), there is severe abnormal blood vessel growth that significantly impacts the retina. This is characterized by the development of new, fragile blood vessels that grow inappropriately, which can pose a serious risk of complications. The abnormal blood vessels typically grow into the vitreous, the gel-like substance that fills the eye, and may lead to other issues such as bleeding or scarring of the retina.

Stage 3 is a critical phase, as the formation of these vessels can potentially lead to more severe conditions such as retinal detachment if not managed appropriately. This stage is a progression from earlier stages, where the abnormalities in blood vessel growth are less severe.

It’s important to understand that other stages of ROP involve different levels of severity. For instance, earlier stages might involve minor issues, while Stage 3 specifically denotes a significant escalation in the pathology, making timely intervention crucial.
