Abstract

PURPOSE: Previous studies in older adults suggest that longer axial length is associated with narrower arteriolar caliber. In this study, we re-examined this relationship in a cohort of children, while controlling for the effects of ocular magnification. DESIGN: Cross-sectional study of 767 children aged 7 to 9 years. METHODS: Retinal vascular calibers were measured from retinal photographs using a computer-based program. Ocular magnification was corrected using the Bengtsson formula. Standardized examination of refraction and ultrasound ocular biometry was performed for all children. RESULTS: In models that adjusted for age, gender, ethnicity, body mass index, blood pressure, and birth weig..
