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…

The "Motor-Free Visual Perception Test-fourth edition" (MVPT-4) is a revised version of the "Motor-Free Visual Perception Test-third edition." The MVPT-4 is used to assess the visual-perceptual ability of individuals aged 4.0 through 80+ years via a series of visual-perceptual tasks that do not require a motor response. Test…

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…

The Parsons Visual Acuity Test (PVAT) described in the article has been developed for use with difficult-to-test individuals previously labeled untestable. The studies reported support use of the PVAT as an alternative screening procedure for identifying difficult-to-test persons who are in need of a professional eye examination. (Author/CL)

Tested the validity of the Mandola Colorvision Screening Test, a color confusion test involving geometric designs and a tracing technique, as a screening test for color vision defects in 82 preschool and kindergarten children. Results indicated that MCST separates medium to strong color vision defects from the normal population. (JAC)

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)

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.

A vision screening program established at a facility for 271 individuals with severe or profound mental retardation used the acuity card procedure as its measure. The procedure was found to be a valid and reliable screening tool for this population. A few residents had good visual acuities, whereas the acuities of others were poor. (JDD)
