Horizontal lines at +2.00 diopters and −0.50 diopter represent definition thresholds for hyperopia and myopia, respectively. Children temporarily absent from the area, those staying in boarding schools, and institutionalized subjects (e.g., those in special schools for the handicapped) were also enumerated.

Neither difference was significantly different from zero (paired t-test, P = 0.212 and P = 0.429). this contact form Reproducibility for cycloplegic autorefraction was comparable, with mean test–retest differences of −0.016 ± 0.235 D for right eyes and +0.002 ± 0.235 D for left eyes. Reproducibility of cycloplegic retinoscopy and autorefraction was also found to be good in test–retest evaluations—within 0.50 D for 95% of measurements, with statistically insignificant mean differences. doi:10.1167/iovs.03-1051 Views Full Article Figures Tables PDF Share E-mail Facebook Twitter Google Digg Delicious CiteULike Tumblr StumbleUpon Tools Alerts User Alerts You are adding an alert for: Refractive Error and Visual

The higher prevalence found with autorefraction was because of mild/moderate forms of astigmatism. The deficit of 15-year-olds was because of an inconsistency in the way age, in years, was defined during the enumeration versus the way it is defined here and in the other or Subscribe Now AdvancedSearch All Journals IOVS JOV TVST Issues Topics For Authors About Editorial Board Subscriptions March 2004 Volume 45, Issue 3 ‹ Issue › Jump To...
