This study aimed to develop a valid and reliable instrument that measures the functional vision of students with low vision. Thus, an assessment tool and performance activities were developed for three vision skill groups (near vision skills, distance vision skills, and visual field) that include functional vision skills. The universe was 1485…

This paper presents a case study designed to educate students in pre-service teacher education programs about the importance of a comprehensive eye exam. The case study chronicles a family's multi-year search for solutions to their child's reading difficulties. The research supporting the case study explores the connection between vision…

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…

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…

As follow up to a study which compared forced-choice preferential looking (FPL) with pattern visual evoked potential (VEP), this study increased the VEP success rate and improved agreement between the FPL and VEP acuity estimates by using horizontal bar stimuli for young preverbal children (n=17) with nystagmus.

This article describes the development and evaluation of a short form of the 24-item Adaptation to Age-Related Vision Loss (AVL) scale. The evaluation provided evidence of the reliability and validity of the short form (the AVL12), for significant interindividual differences at the baseline and for individual-level change in AVL scores over time.…

The Pepper Visual Skills for Reading Test was assessed as a measure of reading ability with meaningful text in 38 adults with macular degeneration; scores were compared with assessment made using the Gray Oral Reading Test, a previously standardized assessment. The test's validity was confirmed. (Author/JDD)

Statistical analyses of scores on subtests of the Intelligence Test for Visually Impaired Children were done for two groups of children, either with or without usable vision. Results suggest that the battery has differential factorial and predictive validity. (Author/DB)

When assessing the visual function of young children, it is important to use a variety of tests. It is essential to have a structured observation method when it is not possible to use ordinary acuity tests. A structured observation method can be created by using a checklist. An ideal checklist should be handy and reliable and include a minimum of…

Fifty adults (ages 28-86) with macular degeneration were given the Low Vision Reading Comprehension Assessment (LVRCA) to test its reliability and validity in evaluating the reading comprehension of those with vision impairments. The LVRCA was found to take only nine minutes to administer and was a valid and reliable tool. (CR)

The study evaluated the validity, reliability, and effectiveness in providing needed information of the Montana Functional Vision Assessment (MFVA) Instrument by comparing it with the Texas Education Agency Functional Vision Assessment and field testing the instrument in evaluations of nine multihandicapped students (ages 3-11). Evaluation led to…

This article summarizes results of statistical analyses of an intelligence test for 155 braille-educated blind and low-vision children, aged 6-15, in the Netherlands. Results indicate some accuracy in predicting academic achievement; factor analysis indicates 4 interpretable factors in children with and without usable vision. (Author/PB)

The investigation was undertaken to obtain data on the number of kindergarten, second, and seventh grade Ss classified as having color vision defects by the American Optical-Hardy, Rand, Rittler Test (AO-HRR) and two tests by S. Ishihara. Also studied was the ability of color vision defective and color normal Ss to utilize color as measured by the…
