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…

Summey, Pamela S. – Sight-Saving Review, 1978
The study assesses the impact of a visual screening effort using the Ophthalmetron (a device which permits rapid screening for refractive error) on 550 kindergarten through eighth-grade students. Findings showed that only 38 percent of those children referred to an ophthalmologist actually went. (PHR)

Peer reviewedSzlyk, J. P.; And Others – Journal of Visual Impairment and Blindness, 1990
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…

Peer reviewedBane, M. C.; Birch, E. E. – Journal of Visual Impairment and Blindness, 1992
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.

Peer reviewedSchanel-Klitsch, E. – Journal of Visual Impairment and Blindness, 1992
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)

Peer reviewedWilkinson, M. E.; Stewart, I. – Journal of Visual Impairment and Blindness, 1993
Records of 360 students evaluated via outreach programs at the low vision clinics of the Iowa Braille and Sight Saving School over a 10-year period were analyzed concerning age, sex, ocular condition, best-corrected visual acuity at far and near, and recommended optical devices. (JDD)

Peer reviewedDodds, Allan G.; Davis, Denis P. – International Journal of Rehabilitation Research, 1987
To develop a battery of tasks to predict and improve mobility performance, a series of functional vision tasks (texural shearing, degraded images, embedded figures, and parafoveal attention) were generated by a microcomputer. Sixty visually impaired subjects given either computerized task training or real-life training improved their low vision…
