The New York State Optometric Association (NYSOA) Vision Screening Battery was administered to 1983 grade school children. Complete visual examinations were performed on 125 children. A consensus method for determining a diagnosis was developed and a double-blind paradigm was used to validate the screening battery. The sensitivity was found to be 71.7% and the specificity to be 65%. When compared to the Snellen test, the NYSOA battery is far more sensitive. The Snellen test is 100% specific but misses 75.5% of the children found to have vision problems when given a complete visual examination.
