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

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 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, syil x7 price 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 and p = 0.390).AL and AL/CR ratio differed significantly by refractive error status (p Conclusions: AL and CR differ significantly by citronella horse shampoo 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.
