Baltimore's school-based vision-screening program may be leaving thousands of children with uncorrected eyesight problems. Vision screening in public schools is essential for students to learn, especially when low-income children face a high rate of eyesight problems and have poor access to health care. Left undetected and uncorrected, vision…

This report examines the causes of error in two techniques for measuring eye fixation position. Theoretical calculations of the magnitude of sources of error are shown to produce good agreement with empirically derived magnitudes for adult and neonate eyes.

Three experiments are reported in which 15 babies were presented with visual stimuli which varied in shape and distance from the eye. Results indicated that the majority of subjects binocularly fixated all three stimuli and it was concluded that the newborn baby has the basic requirements for binocular vision. (Author/GO)

The assessment of visual acuity in the preverbal child is reviewed. Four techniques are discussed: optodinetic nystagmus, forced choice preferential looking, visually evoked potential, and electroretinography. Development of binocularity and refractive changes are traced. (CL)

An evaluation of present screening procedures for chronic open-angle glaucoma includes suggestions for improvement: greater distribution of screening and education, conversion from monophasic to multiphasic screen, and examination of visual fields, optic nerve, and medical history in addition to the tonometry currently done.

By testing students for depth perception, instructors can identify those students whose monocular vision prevents them from properly drawing three-dimensional objects. (SK)

Two experiments assessed the extent of newborns' ability to discriminate color. Results imply that newborns have some, albeit limited, capacity to discriminate chromatic from achromatic stimuli, and hence, are at least dichromats. (Author/DR)

Results of three factor analyses on the Frostig DTVP subtests indicated that the test measures one general visual perception factor, rather than the five postulated by Frostig. (Author/KW)

The most commonly used chart for testing eye acuity is the Snellen Chart, developed more than 100 years ago. A description is given of the way this chart works, its uses, and its limitations. (JD)

Special Olympics provides sporting opportunities for people with intellectual disabilities (ID), and Lions Clubs International Opening Eyes GB offers vision screening for athletes at Special Olympics Games. Opening Eyes GB screened the vision of 505 UK athletes at its inaugural event in 2001. The results were analysed and are presented here.…

Purpose: It has long been known that children with specific language impairment (SLI) can demonstrate difficulty with auditory speech perception. However, speech perception can also involve the integration of both auditory and visual articulatory information. Method: Fifty-six preschool children, half with and half without SLI, were studied in…

The booklet, another in a series for parents of deaf blind children, presents information in large type about the nature and cause of deaf blindness. A drawing of the ear is followed by a simplified discussion of the ear's functioning and definitions of terms (such as spondee threshold) used in hearing testing and hearing loss. Similarly, a…

To determine which children in the Head Start program may have vision problems, Head Start teachers and staff do vision "screening." This booklet demonstrates how to do the screening using the Snellen "E Chart." Trouble signs that the test administrator should be aware of are listed, and vision scores are explained simply.…
