Abstract
Determine whether intravitreal injection of bevacizumab (IVB) exerts long-term effects on neurodevelopmental outcomes in children with retinopathy of prematurity (ROP) when reaching the age of 8 years. We enrolled 277 children. Patients were stratified into the groups full-term, preterm without ROP, ROP without treatment, or ROP with treatment, based on gestational age (GA) and ROP status. Children under GA of 37 weeks were considered premature. Patients' cognitive outcomes were evaluated using Full-Scale Intelligence Quotient (FIQ) (full score and percentile) generated by the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) every 1 to 2 years. At the mean age of 7.8 years, ROP without and with treatment groups demonstrated lower FIQ scores and percentiles, compared with full-term and premature groups (both p<0.05). FIQ scores and percentiles didn't significantly differ between patients who received different treatments for ROP (full score p=0.19; percentile p=0.37). After adjusting for GA, LogMAR best corrected visual acuity (BCVA) was negatively associated with FIQ scores (p=0.0008) and percentiles (p=0.0002). At the mean age of 8 years, patients with ROP undergoing IVB didn't exhibit worse cognitive outcomes than those who underwent laser photocoagulation or both treatments. GA and BCVA correlated with cognitive development in children.
