The objective of this review is to evaluate treatments for homonymous visual field defects (HVFDs). We distinguish between three treatments: visual restoration training (VRT), optical aids, and compensatory training. VRT is both the most ambitious and controversial approach, aiming to restore portions of the lost visual field. While early studies suggested that VRT can reduce the visual field d...

i ABSTRACT The objective of this project was to evaluate human factors based cognitive aids on endoscope reprocessing. The project stems from recent failures in reprocessing (cleaning) endoscopes, contributing to the spread of harmful bacterial and viral agents between patients. Three themes were found to represent a majority of problems: 1) lack of visibility (parts and tools were difficult to...

This paper describes the design and development of an expert system that aids in the recommendation of computer access technology visual aids for the severely visually handicapped. The primary focus here is on a description of the frame structure used to represent the knowledge base and the accompanying search strategy which takes advantage of this frame structure.

THOSE who are substantially and permanently handicapped by defective vision resulting from illness, injury, or congenital deformity may be described as partially sighted. The following criteria are suggested as a general guide in estimating " substantial handicap": (1) Visual acuity 3/60 to 6/60, with full visual fields. (2) Visual acuity up to 6/24, with moderate contraction of the visual fiel...

PURPOSE We measured the perimetric performance in patients with either acquired immunodeficiency syndrome (AIDS) or human immunodeficiency virus (HIV) disease but without AIDS. METHODS Light-difference sensitivity in the central field was measured in 74 eyes of 37 patients. The Humphrey Field Analyzer 640, program 30-2 was used. Additionally, 143 eyes of 143 normal control subjects were studi...

INTRODUCTION A number of vision defects have been reported in association with albinism, such as photophobia, nystagmus and astigmatism. In many cases only prescription sunglasses are prescribed. In this report, the effectiveness of low-vision rehabilitation in albinism, which included prescription of multiple visual aids, is discussed. CASE PRESENTATION We present the case of a 21-year-old A...

Science students can benefit from visual aids. In biology lectures, visual aids are usually limited to tables, figures, and PowerPoint presentations. In this IRB-approved study, we examined the effectiveness of the use of five prop demonstrations, three of which are at the intersection of biology and chemistry, in three community college biology courses. We hypothesized that students' performan...

Sexually Transmitted Diseases (STDs)-including HIV/AIDS-are among the most common infectious diseases in young adults. How can we effectively promote prevention and detection of STDs in this high risk population? In a two-phase longitudinal experiment we examined the effects of a brief risk awareness intervention (i.e., a sexual health information brochure) in a large sample of sexually active ...
