Refractive Error And Ethnicity In Children


Mean axial length was shorter in the European Caucasian and the Middle Eastern subgroups (Table 3). However, anterior chamber depth in European Caucasian children was similar to that in South Asian children and Middle Eastern children (both P>0.05). Whites had the lowest prevalence of myopia (4.4%), which was not significantly different from African Americans (6.6%). Mutti DO, Zadnik K, Fusaro RE, Friedman NE, Sholtz RI, Adams AJ. Source

Phase 1 investigates additional factors that may predict the onset of juvenile myopia (accommodative function, peripheral refractive error, intraocular pressure, and school achievement). The mean SE (+0.49 D) was just within the emmetropic range.Comparison of refractive error prevalence rates with other studies is difficult due to the use of different definitions, instrumentation, variable use of By checking this box, you'll stay logged in until you logout.

Tonic accommodation, age, and refractive error in children. A spherical equivalent of -0.5 diopter (D) or worse was defined as myopia, +2.50 D or more was defined as hyperopia and a cylinder refraction greater than 0.75 D was considered The mean axial length in boys (23.58 mm) and girls (23.18 mm) obtained by IOLMaster in our study were actually comparable to those reported by Zadnik et al20 for similarly aged children (23.55 No abnormalities were found in brain imaging tests.

Whites had the lowest prevalence of myopia (4.4%), which was not significantly different from African Americans (6.6%). The low incidence of accommodation insufficiency in myopia may result from the amplitude of accommodation which is higher in myopes than in emmetropes and hypermetropes [13]. "[Show abstract] [Hide abstract] ABSTRACT: Collaborative Longitudinal Evaluation Of Ethnicity And Refractive Error In children or young adults, Kleinstein et al [Kleinstein et al, 2003] found that 28% of their US-based study population aged 5 to 17 years had astigmatism of at least 1.0 These values are consistently higher than the low prevalence of myopia in 12-year-old European Caucasian children reported in this study (4.6%).The overall prevalence of myopia in the current study was very
