Ocular Biometry Distribution and One-Year Growth in Eight-Year-Old Southern European Schoolchildren Under the CISViT Project

Blog Article

Objective: To analyse variations in axial length (AL), corneal radius (CR) and the AL/CR ratio over one year in eight-year-old schoolchildren, considering sex, ethnicity and refractive error.Methods: Vision screenings were conducted in 16 schools in Terrassa (Barcelona, Spain) with eight-year-old children as part mitigated gall of the CISViT project.Measurements included ocular biometrics (AL and CR) and non-cycloplegic autorefraction for refractive error.Parental questionnaires provided demographic data (birth date, ethnicity).The same procedures were repeated after one year.

Results: Ocular biometric parameters differed by sex and ethnicity.Boys and children of Maghreb descent had longer AL and flatter CR than girls and Caucasian children (p p = 0.002 in the initial visit and p = 0.011 in the follow-up visit) but consistent across ethnicities (p = 0.291 manomasa promo and p = 0.

390).AL and AL/CR ratio differed significantly by refractive error status (p Conclusions: AL and CR differ significantly by sex and ethnicity, with demographic differences evident in baseline measurements but not in growth rates over one year.The consistency of the AL/CR ratio across ethnicities, despite sex-based differences, supports its utility as a reliable metric for assessing refractive development in diverse populations.
