Visual Impairments (VIs) are ranked as the fourth most common disability in the United States and are viewed as the most common restricting condition during childhood. It has been reported that 17% to 25% of school-aged children have some degree of a vision problem, thus interrupting their potential to reach optimal growth and learning in school.…

The manual was intended to help school personnel (either an educator of the visually handicapped and/or a certified orientation and mobility instructor) evaluate the functional use of residual vision. The manual is organized in three major sections, which cover the following: (1) the general areas addressed in functional vision evaluation (such as…

This article reports on a study of the methods that 21 ophthalmologists used to assess the visual acuity of children with multiple impairments and the difficulties they encountered. Additional means of assessing visual function and alternative means of communicating the results are suggested. (Author/DB)

The study assessed variations in the indoor and outdoor locomotor mobility of 22 low-vision adults, under normal and reduced illumination. Subjects' visual fields and contrast sensitivities accounted for 39 percent of the variation in mobility performance, whereas their visual acuities were not related to mobility performance.

This study found that, of 18 children with severe visual and multiple impairments assessed using the Acuity Card Procedure (originally developed for assessing the visual acuity of infants), 42 percent responded. A similar group received a simple instructional intervention prior to testing and that group's response rate was 85 percent. (Author/DB)

Strabismus and amblyopia are two common childhood vision conditions requiring early identification and treatment. Screening devices include external examination of the eye, ability to track, a cover test, acuity tests, and stereoscopic tests. Treatment includes patching therapy, use of glasses, orthoptics, CAM vision stimulator, or a combination…

The visual acuity of 8 children, aged 2-7, with low vision and multiple handicaps was effectively tested using the Teller Acuity Cards and a preferential-looking procedure with operant modification. This inexpensive procedure was found to be suitable for at-home testing by itinerant vision specialists in developing countries or rural areas. (DB)

Presents a checklist that was created so that parents, teachers, and others could obtain from vision specialists information necessary to ameliorate learning conditions efficiently. (FL)

A task force of opticians and educators in British Columbia was assembled to determine the knowledge and skills required of dispensing opticians and contact lens specialists. The ideas generated by the task force were analyzed and distilled into the standardized tasks listed in this document, using Krathwohl's taxonomy. The document contains 36…

Describes a corrective method of color adaptation designed to allow most, if not all, individuals to participate in the learning process as well as social and work-related environments. Provides a concise summation of facts and theories concerning color deficiency. Includes anatomical drawings, graphs, and statistical data. (MJP)
