Anti-vascular endothelial growth factor intravitreal therapy for retinopathy of prematurity

Retinopathy of prematurity treatment modalities have expanded over the years, from cryotherapy to laser therapy and now, anti-vascular endothelial factor (VEGF) therapy by intravitreal injection. Use of anti-VEGF treatment varies regionally and depends on multiple factors including severity and progression of ROP, availability of alternative treatments, experience of the local ophthalmologists, medical status of the infant, and expectations for long-term follow-up. While the advantages and disadvantages of anti-VEGF intravitreal treatment on the eye are relatively well-described, few studies provide information about potential long-term systemic effects of this treatment, which is known to transiently reduce systemic VEGF concentrations.
