Incidence and Risk Factors for Persistent Avascular Retina in Patients with a History of Retinopathy of Prematurity in Mexico.

Persistent avascular retina appears to result from a complex interplay of prenatal and postnatal factors affecting retinal vascular development.

Patients requiring repeated anti-VEGF treatment and those exposed to adverse maternal conditions may represent a subgroup at increased risk for incomplete peripheral retinal vascularization, supporting the need for long-term retinal surveillance after retinopathy of prematurity regression.
