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.

Nine schools (two kindergartens, four primary, and three secondary) and two community facilities, scheduled throughout the course of the study, were identified for interobserver reproducibility testing. The 95% limits of agreement were −0.747 to +0.432 D for right eyes and −0.739 to +0.447 D for left eyes. The 95% upper and lower limits of agreement around mean differences 11 were −0.469 to +0.438 D for right eye measurements and −0.399 to +0.416 D for left eyes. https://www.researchgate.net/publication/12551372_Refractive_Error_Study_in_Children_Results_from_Shunyi_District_China Warning: The NCBI web site requires JavaScript to function.

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
