Povidone-iodine (PI) is the standard antiseptic for intravitreal injections (IVIs), while chlorhexidine (CHX) is a potential alternative. The efficacy of PI versus CHX in preventing endophthalmitis remains debated, with studies showing mixed results.

The Childhood Executive Functioning Inventory (CHEXI) is a rating scale that evaluates everyday behaviors associated with executive functions in children. This study aimed to investigate the factor structure and the measurement invariance across parents and teachers of the CHEXI in a sample of 279 Portuguese typically developing children (6 to 12 years old,  = 160 girls and  = 119 boys). Most studies only analyzed the original two-factor model, and the few that investigated the four-factor model found a nearly identical fit between both factor structures.
