Evaluation of Infants with Retinopathy of Prematurity Treated with Intravitreal Bevacizumab

Abstract

Objective: To evaluate the systemic and local effects and side effects of intravitreal bevacizumab injection in preterm infants with aggressive posterior retinopathy of prematurity. Material and Methods: A total of 16 patients were included in this single-center observational cohort study between June 2020 and March 2021. The clinical, laboratory, and radiological findings before and after intravitreal injection of 0.3 mg bevacizumab were recorded for a total of 32 eyes. Results: The patients’ mean gestational age at birth was 25±0.38 weeks and their mean birth weight was 695±119.2 g. None of the patients developed complications such as local vitreous hemorrhage or endophthalmitis secondary to intravitreal injection administered at a postmenstrual age of 34 weeks, and none required repeated injections. There was no increase in the rate of intraventricular hemorrhage after injection. There was no statistically significant difference in the patients’ laboratory parameters, blood pressure values, or systemic findings before and after treatment. Conclusion: Although no systemic or local side effects were observed in patients treated with intravitreal bevacizumab injection in this study, patients should be monitored closely for systemic hypertension, intraventricular hemorrhage, and hypotension. More detailed studies are needed to evaluate later neurodevelopmental outcomes compared to other treatment options.
