Assessing the predictive ability of the test-positive findings of an elementary school vision screening.
The purpose of this study is to assess the predictive ability of the test-positive findings of an elementary school vision screening program, conducted by 2nd-year optometry students, in identifying children with eye or vision disorders.
A modified version of the Modified Clinical Technique (MCT) vision screening was administered to elementary children from a below-average socioeconomic neighborhood in Houston, Texas.
Comprehensive eye and vision examinations were provided to the available children who failed the vision screening.
The screening was administered by groups of 2nd-year optometry students with the assistance of a 4th-year optometry student, and supervised by a faculty member licensed to practice optometry.
The follow-up examinations were provided by supervised 4th-year optometry students in a clinical setting based at the elementary school.
Positive predictive values calculated from the screening and examination findings estimate the probability that a failure on one or more of the screening tests would identify children with eye or vision disorders.
Sixty-nine percent of the test-positive children examined were found to be true positives by the criteria developed in a study of vision screening methods in Orinda, California from 1954 through 1956. (...)
