Compared was the incidence of lateral phoria, a tendency for the eyes to turn in or out, in 45 elementary grade learning disabled children and 364 children in regular elementary education classes. (DB)

A comparison study involving 50 second-through-fifth graders was designed to analyze the relationships between the incidence of visual abnormalities and high and low academic achievement. Data suggested that children with deficient visual skills may experience greater problems academically. (SBH)

Studied were eye coordination and effects of fatigue on vision in the visual and academic functioning of 1049 students in grades 1 through 10. An earlier study (1966) examined the eye coordination of 1152 students in grades 1 through 12. The common Snellen Test of Visual Acuity failed to indicate 42% of students who were diagnosed by other tests…

A study of 156 hearing impaired students (ages 3 to 14 years) was undertaken to see how many of the Ss suffered from a visual anomaly (disease, refractive error, or binocularity). (PHR)

Evaluated was retinal functioning of 15 4-year-old children who had received phototherapy for neonatal hyperbilirubinemia (jaundice). (DB)

A validation study of the vision test battery used in the Health Examination Survey of 1966-1970 was conducted among 210 youths 12-17 years-old who had been part of the larger survey. The study was designed to discover the degree of correspondence between survey test results and clinical examination by an opthalmologist in determining the…

An adaptation of the Visual Efficiency Scale, which incorporated familiar three-dimensional objects into the task, resulted in a more successful measure of visual proficiency when tested with 15 developmentally delayed kindergarten and primary grade children. (PHR)

Reported were extensive statistical data on the prevalence of abnormal eye conditions found on examination, heterophoria test results, and history of eye problems as well as extent of interrelationship of the eye examination and vision test findings among children aged 6 to 11 years in the United States, based on findings from the Health…

The study was designed to investigate the validity and reliability of the Motor-Free Visual Perception Test (MVPT) when used with 46 educable mentally retarded Ss (6-8 years old). (Author/SBH)
