Vision screening in children tested at 7, 11, and 16 years.

Distant vision screenings of a national sample of children were performed at the ages of 7, 11, and 16. Many children with normal vision at one screening showed defects at later screenings, and altogether 18% of children with normal vision at the age of 7 had defects by the time they were 16. Twelve per cent of those with normal vision at 7 and 11 had developed a visual defect by the age of 16. Apparent improvements between screenings probably resulted largely from technical difficulties inherent in testing young children. The results clearly indicate the importance of regular vision screening during the school years and the need for comprehensive but flexible back-up services.

Assessment of the Queensland School Health Service vision screening programme.

Despite the widespread acceptance of vision screening programmes as a means of detecting ocular disorders in children, there has been little formal assessment of their validity and reliability. One such screening programme is conducted in Queensland State Primary Schools by the Division of School Health Services of the State Department of Health. A group of 877 children was screened by the Service and subsequently subjected to a formal independent ophthalmological examination. A comparison of the results of these procedures revealed that the visual screen as performed by the Service was highly accurate in the determination of distant visual acuity. Detection of manifest strabismus was less satisfactory, with between 30 and 74% of sufferers being detected. There is no evidence to suggest that a more complex protocol will improve the detection of ocular disorders. Rather, a more effective implementation of the current screening procedure is required.

A vision screening of a Down's syndrome population.

A vision screening of 55 (24 male, 31 female) Down's syndrome children was done by SUNY vision training residents. In the past, similar screenings have been done with older children. The children in this study ranged in age from 2 years, 2 months, to 8 years, 5 months. The median age was about 3.5 years. This study will enable vision care practitioners to be more aware of visual conditions in this population which have a greater incidence than the normal population.

Vision screening and the private practitioner--a status report.

Private optometric practitioners have traditionally been involved with schools and other organizations in conducting vision screening programs, although the extent of the involvement varies considerably from one location to another. A national survey of 500 optometrists (49% response rate) was conducted to examine the extent of optometric involvement in screening programs. Seventy percent of the optometrists surveyed have participated in screening during their professional careers although only 30% are currently active. Most screenings were done in the schools with the Modified Clinical Technique (MCT) battery although only 7% knew of perceptual screening activities. The study indicates that in areas where vision screening is conducted, most practitioners are involved and where programs are infrequent, knowledge about screenings is limited.

Vision screening of adolescents and their use of glasses.

Vision screening was performed in over 11 000 16-year-olds who were taking part in the National Child Development Study. For distance vision 75% had normal acuity, 9% a minor defect, and 16% a more severe unilateral or bilateral defect. For near vision 85% had normal vision, 8% a minor defect, and 7% a unilateral or bilateral defect. Few children (62) with normal distant vision had defects in near vision, though many more (607) had both poor distant vision and poor near vision. Vision defects were more common in girls than in boys and occurred more often in adolescents from non-manual than manual families. Athough 18% of children had been prescribed glasses for current use, a third did not have their glasses available at the examination: 27% of the children prescribed glasses had normal unaided distant visual acuity or only a minor defect, and they constituted 42% of those who were not wearing their glasses. Further investigation is needed into the criteria on which glasses are prescribed for children and into the reasons for which they are not worn.

Vision screening of specialized populations.

This paper describes the vision screening tests for specialized populations as used by the Community Eye Care Services Program of the Pennsylvania College of Optometry. Referral criteria have been elaborated. This paper is designed to help those who are interested in organizing such a screening.

Is school vision screening effective?

A population-based cohort of all children entering kindergarten in a three-year period (N = 2,938) was followed retrospectively from kindergarten through 12th grade to estimate incidence of abnormal school vision screening tests and rates of follow-up by community ophthalmologists or optometrists. Overall 28% of children had at least one abnormal school vision screening test. Abnormal screening with referral increased from 1.2% of five-year-olds to 9.1% of 13-year-olds. Overall, 91% of children referred had further evaluation by eye care professionals. However, visits to an eye care professional often were delayed; median time was 0.8 years for children seeing an ophthalmologist and 1.8 years for children seeing an optometrist. Results support the continued use of simple visual acuity screening in schools. Consideration should be given to screening children beyond age 12 and developing methods to increase the rapidity of parental response to referral recommendations.
