This article describes a device, the Visual Hand Display, used by pediatric ophthalmologists at the Children's Low Vision Center (Boston) to evaluate a child's postoperative visual functioning. The device consists of different sized black stripes on white circles and a face. (DB)

Visual persistence was investigated in adults with and without dyslexia in order to determine whether dyslexic adults demonstrate problems similar to those found in childhood dyslexia. Results showed that sensitivity of dyslexic adults was impaired when parts of a test stimulus were presented to adjacent retinal areas, suggesting that under…

USING A SAMPLE OF 94 CHILDREN (31 TO 54 MONTHS OLD), THIS STUDY COMPARED EIGHT VISION SCREENING PROCEDURES FOR YOUNG CHILDREN IN THE ABILITY TO TEST FOR SEVERAL VISUAL FUNCTIONS, AND PREFERENCE AMONG THEM BY CHILDREN. THE SUBJECTS WERE ORIGINALLY TESTED USING THE EIGHT SCREENING TESTS, AND 6 MONTHS LATER 40 OF THE CHILDREN WERE RETESTED FOR…

The relationship of astigmatism to reading and the possible detrimental effects it might have on reading were investigated. The greatest incidence of astigmatism was for the with-the-rule type ranging from .50 to 1.00 diopter. This type of astigmatism was induced in 35 seniors from the Los Angeles College of Optometry by placing cylindrical lenses…

In order to assess vision in Alzheimer's disease, gerontologists must use tests that make minimal cognitive demands on the subject. Using such tests revealed a pattern of deficits in color discrimination, stereoacuity, contrast sensitivity, and backward masking. Impaired vision predicts deficient performance on numerous tests of cognition. (JPS)

Vision assessments were provided to 297 preschoolers in nine Head Start programs in New York State. The protocol used provided a thorough evaluation and required only seven minutes per child. Sixty-three children (21.2%) were referred for further evaluation. Visual deficits detected included decreased acuity, strabismus, astigmatism, and…

This study assesses the validity of an interview questionnaire designed to predict performance by low-vision adults (N=41) on tasks of finding, detecting, scanning, and tracking. Subjects' ratings of difficulty with these tasks were compared to ratings of trained professionals. Results indicate self-report may be of some value in predicting…

Although several vision screening techniques are available for infants, none is routinely used. Visual deficits are often first detected through required preschool vision screenings, which vary in their comprehensiveness. No standardization for testing or administration exists. Some of the testing procedures used may have inappropriately high…

Seventeen visually impaired children, aged 7-11 years, were compared with sighted children on a test of facial recognition and a test of expression identification. The visually impaired children were less able to recognize faces successfully but showed no disadvantage in discerning facial expressions such as happiness, anger, surprise, or fear.…
