Fluorescein Angiography Findings in Treatment-Naive Premature Infants with Retinal Vascular Immaturity and Persistent Avascular Retina.

Even in larger preterm infants and without severe retinopathy and anti-VEGF treatment, PAR and peripheral pigmentary changes may be detected, and mild angiographic vascular activity may continue. These findings may lead to late-onset retinal pathologies that may threaten vision. In eyes with PAR, follow-up with FA and prophylactic laser application may be applicable. Further investigation is required for this topic.
