A recent study conducted at UCLA supported the early neurodevelopmental safety of anti-VEGF treatment, dispelling concerns about its independent association with worse outcomes in various domains among infants undergoing retinopathy of prematurity (ROP) screening. The study results were published in the Journal of JAMA Ophthalmology.
Preterm infants undergoing retinopathy of prematurity (ROP) screening exhibit diverse neurodevelopmental outcomes, posing challenges in prediction. This retrospective cohort study aims to unravel the potential associations between socioeconomic and clinical factors and neurodevelopmental outcomes in a varied, multicenter cohort of premature neonates subjected to ROP screening.

Conducted across academic and community neonatal intensive care units, this study involved 706 infants meeting the American Academy of Pediatrics ROP screening criteria. Data from electronic medical records and US Census Bureau income data were analyzed, encompassing demographic and clinical information, proxy household income, and health insurance type. Neurodevelopmental assessments were performed using the Bayley Scales of Infant and Toddler Development (BSID) between 0 and 36 months of adjusted age. The main outcome of measurement was assessing the neurodevelopmental outcomes in the cognitive, language, and motor domains measured via BSID.
Results:
In a multivariable model adjusting for various factors, public health insurance emerged as a significant predictor, associated with a fourfold increased risk of moderate to severe neurodevelopmental impairment (NDI) in cognitive and language domains, and a threefold increased risk in the motor domain.
Additional clinical factors contributing to increased NDI risk included lower birth weight, intraventricular hemorrhage (IVH) diagnosis, male sex, and older age at Bayley assessment.
Interestingly, infants undergoing laser or anti-VEGF treatment for ROP exhibited lower BSID scores initially, but in the adjusted model, treatment type was not independently associated with worse neurodevelopmental outcomes in any domain.
The study underscores the intricate relationship between socioeconomic factors and neurodevelopmental outcomes in preterm infants screened for ROP. Notably, the public insurance type was associated with heightened NDI risk, emphasizing the need for comprehensive, inclusive care strategies. Furthermore, the study supports the early neurodevelopmental safety of anti-VEGF treatment, dispelling concerns about its independent association with worse outcomes in various domains.

These findings prompt a reevaluation of the intricate interplay between socioeconomic factors, clinical variables, and neurodevelopmental outcomes in preterm infants. Tailored interventions for those with public insurance may be warranted to address the heightened risk of NDI. Additionally, the study contributes valuable insights into the safety of anti-VEGF treatment, reassuring clinicians about its impact on neurodevelopmental outcomes. Future research could delve deeper into understanding the mechanisms underlying these associations, fostering improved care practices for this vulnerable population.
