Abstract

Purpose: To compare refraction and ocular biometry in European Caucasian children aged 6-7 years and 12-13 years living in Sydney, Australia and Northern Ireland. Methods: All children had a comprehensive eye examination, including cycloplegic (cyclopentolate 1%) autorefraction (Sydney; Canon RK-F1, Northern Ireland; Shin-Nippon SRW-5000) and ocular biometry (IOLMaster, Carl Ziess). Hyperopia was defined as a right spherical equivalent refraction (SER) of ≥+2.00 dioptres (D), myopia as ≤-0.50D and astigmatism as a cylindrical error of ≥1.00D.Results: The mean SER was similar at age 6-7 yrs (p=0.9), however, at 12-13 yrs, children in Northern Ireland had a significantly less hyperopic mean SER (+0.66D) than children in Sydney (+0.83D, p=0.008). The prevalence of myopia, hyperopia and astigmatism was significantly greater in Northern Ireland than Sydney at both ages (all p
