Various tests have been devised to assess eye movement abilities. Although they have been normed to a general population, comparisons between those with learning/reading difficulties and the normal population has not been thoroughly investigated. This study attempts to evaluate the eye movement abilities of a reading delayed population. Seventy-four reading delayed subjects were given three different eye movement tests as an adjunct to the standard vision screening procedure. The Groffman Visual Tracing Test, the Pierce Saccade Test and the Stern Saccadic Fixation Test were administered to the subjects at the end of a primary screening. Eye movements were analyzed based on the subject's "actual age scores" and "expected age scores". The subjects were found to have eye movement deficiencies significant to the 0.005 level. The findings suggest that eye movements measured on the Groffman, Stern, and Pierce may provide another screening method for detecting individuals with reading deficiencies.
