Question Can anti–vascular endothelial growth factor (VEGF) therapy in retinopathy of prematurity (ROP) be improved by using ranibizumab given at lower doses than the standard treatment, bevacizumab, thus alleviating systemic safety concerns while effectively treating disease?
Findings In this randomized clinical trial with 20 patients, both investigated ranibizumab doses were lower than the current standard bevacizumab dose for ROP. Both ranibizumab doses were effective in controlling acute ROP (17 of 18 per protocol treated eyes [94%] with 0.12 mg and 13 of 14 per protocol treated eyes [93%] with 0.20 mg); systemic VEGF levels remained unchanged.
Meaning Low-dose ranibizumab is effective in treating acute ROP without suppressing plasma VEGF levels.
