Clinicians have significantly improved the management of severe retinopathy of prematurity (ROP) with the advent of anti-vascular endothelial growth factor (VEGF) therapy. Specifically, aflibercept in ROP has emerged as a promising tool for experts dealing with aggressive posterior disease. This agent acts as a potent VEGF trap with high binding affinity. Consequently, it offers prolonged intraocular activity compared to shorter-acting medications. Many researchers believe these unique properties help reduce the risk of late disease recurrence while preserving peripheral retinal tissue.
Recent clinical investigations have provided valuable insights into the efficacy of this treatment. Early retrospective studies utilized a 1 mg dose, which resulted in rapid regression of the disease. Furthermore, patients treated with aflibercept often experienced better refractive outcomes than those receiving laser therapy. Following these early findings, the pivotal FIREFLEYE and BUTTERFLEYE randomized controlled trials evaluated a lower 0.4 mg dose. These studies demonstrated that aflibercept achieves comparable treatment success to laser photocoagulation. Additionally, the drug preserves the peripheral retina and lowers the incidence of high myopia in growing infants.
While the benefits are clear, practitioners must remain vigilant regarding late complications. Reactivation of ROP after aflibercept treatment typically occurs less frequently and later than with ranibizumab. However, persistent avascular retina remains a primary concern for many neonatologists and ophthalmologists. Therefore, infants require prolonged surveillance to monitor for potential recurrence. If the disease returns, clinicians may use adjunctive laser treatment to ensure stable outcomes. Systemic safety data currently appear reassuring. Short-term studies show no significant adverse effects on growth or neurodevelopmental milestones for these vulnerable infants.
These trials showed that a 0.4 mg dose of aflibercept provides comparable treatment success to laser photocoagulation. Furthermore, infants treated with aflibercept showed lower rates of high myopia and better preservation of the peripheral retina.
Reactivation following aflibercept typically occurs less frequently and later than with ranibizumab. Moreover, its recurrence rate is similar to or lower than that of bevacizumab, though long-term surveillance remains essential for all treated patients.
