The present study examined (1) whether objects, represented in memory by visual cues, are recognized by touch and (2) by what information such representations might be reached, i.e. global shape, context, or components. Seven newly blind, seven congenitally blind, and eight adventitiously blind individuals were tested. The results suggested that representations consisting mainly of visual cues are most proficiently reached by subjects having (1) both visual and tactile experience, i.e. the adventitiously blind, and (2) information about the object’s global shape.

Haptic interface technology has the potential of becoming an important component of access systems for people who are blind or visually disabled. The purpose of this study was to learn more about how a haptic interface, in this case the Phantom from SensAble Technologies, can be used to give blind persons access to 2D graphics and similar computer-based graphics. User tests were carried out with 24 blind users from Sweden and Italy. The tests included mathematical curves, haptic picture reliefs and haptic floor plans. This article reports on both technical solutions and results from the user tests. The results were influenced both by the nature of the different tasks and by individual differences among the test persons. 72% of the users managed to solve the applied mathematical problem that was the task for the mathematics program. The results for the picture reliefs were highly dependent on contextual information: 33%-66% of the users could identify the haptic picture reliefs without contextual cues, whe...

We investigated the mobility performance of legally blind patients with age-related maculopathy (ARM) as assessed by their ability to visually detect hazards in their travel path. The three types of hazards were: drop-offs (a curb), obstacle on the travel surface (a small wastebasket), and a head-height obstacle (a piece of foam insulation projecting across the travel path at head height). We also recorded the patient’s logMAR visual acuity and Pelli-Robson contrast sensitivity. Three distinct daylight assessments were made in a naturalistic outdoor environment: an initial assessment of distance to visually detect each of the three types of hazards; an assessment designed to assess the subject’s maximum potential visual detection distance; and a final assessment following training and fitting with filters to reduce glare to determine the increase, if any, in visual detection distance for the three types of hazards. The inter-rater and test/retest reliabilities of the assessment procedure were studied. The...

Patients with visual field deficits following stroke or neurotrauma can use vision restoration therapy (VRT) to increase their visual field size by about 5° of visual angle.1However, little is known about whether such visual field enlargements are relevant to visually guided activities of daily life. Specifically, we wish to know (1) if VRT affects activities of daily life (ADL) measures, and (2) to what extent any subjective changes correlate with quantitative measures of visual field enlargements. A retrospective analysis was carried out with data of 69 patients that had been interviewed after 6 months of VRT. Patient testimonials were analyzed post hoc and correlated with demographic status and pre/post VRT changes as measured by perimetric testing. As previously described, VRT significantly increased detection ability and most patients (88%) reported subjective benefits in ADL. A correlation analysis of quantitative parameters of visual field enlargements with subjective patient testimonials was perfo...

OBJECTIVE: The purpose of this study was to determine if combining visual acuity (VA) and visual field (VF) measures in the manner proposed in the 1999 Guide for the Evaluation of Visual Impairment1and incorporated into the 5thEdition of AMA Guides for the Evaluation of Permanent Impairment2(Guide) would be more predictive of self-reported vision-targeted quality of life than standard vision measures of VA or VF alone. DESIGN: Visual function and quality of life (QOL) were assessed in 200 visually impaired individuals. Tests included visual acuities, visual fields, and vision specific QOL using the National Eye Institute Visual Function Questionnaire (NEI VFQ). Visual acuities and visual fields were scored in the usual manner and then rescored using methodology proposed in the Guide to derive measures of functional vision. Relationships among the visual function, functional vision and QOL outcomes variables were determined using correlation and stepwise regression analyses RESULTS: High correlations were ...

Visitors to museums are usually not allowed to touch works of art, which means significant restrictions in the experience of art for visually impaired people. A European research project (PURE- FORM), coordinated by PERCRO in Pisa, Italy, indicates a new option. It aims to make possible manual exploration of virtual 3D copies of works of art via a haptic display developed within the project. A selection of statues has been digitized, and virtual 3D copies of them made available for touching. The final goal is that a virtual library of statues will be created that is accessible at all museums having the nec- essary equipment.

Purpose: To report the role of comprehensive low vision services among children who underwent cataract surgery at a tertiary eye-care center in southern India. Study design: A non-comparative retrospective study of consecutive patients. Methods: Forty-four patients referred to the vision rehabilitation centers with a clinical diagnosis of aphakia/pseudophakia in childhood were included in this retrospective study. The patient evaluation included a comprehensive low vision examination. Low vision devices (LVDs) were prescribed on the basis of task analysis, patient performance, and preference. Improvement in at least one WHO category of visual impairment after using the LVDs was considered a success. Results: Applying the WHO criteria of blindness, 54% (14/26) of the low vision subjects (<3/9–1.5/30) improved to the no impairment category (=3/9) and 13% (1/8) of those classified as blind (<1.5/30-NLP) improved to the low vision category after using LVDs.

The brain is responsible for analysing, seeing, and understanding what we see. Image data are transferred from the eyes through the visual system to the occipital lobes where primary visual processing takes place. This process involves resolution (visual acuity), visual field analysis, colour and contrast perception, and the detection and analysis of movement. Recognition of what we see takes place in the temporal lobes. The visual processing which allows us to encompass the whole visual scene and to choose an element of interest, and which facilitates accurate visually guided movement of the body, takes place in the posterior parietal lobes. These systems work in harmony. Any of these processes can be impaired by damage to the brain. Both the outer brain tissue (the grey matter or cortex) and the inner brain tissue (the white matter) serve visual function and can be damaged, resulting in a range of types of visual dysfunction of varying degree. Severe brain damage can result in blindness, with perception...

With the rapid development in technology and learning methods, delivery of content is becoming more computer-dependent. Learning has advanced to interactive learning, problem-based learning (PBL), self- and peer-teaching, and web-based learning among others. The Hong Kong Polytechnic University hosted its low vision rehabilitation course on its in-house website in collaboration with the University of Houston, College of Optometry. Web Course Tools (WebCT) was used to stimulate students and deliver content on the subject of low vision rehabilitation. The site acts as a reference source for course material and laboratory instruction. It includes self-tests, quizzes, diagrams, photos, and some animated simulations for students to better understand and assimilate low vision rehabilitation concepts and principles. With web-based learning, low vision concepts can become easier and more fun. Data gathering, grading, and analysis can be more efficiently performed with advance planning and programming.

The aim of this work is to narratively review findings on emotional and social adjustment among visually impaired older adults. The definition of emotional adjustment employed here includes a decline in mental health, especially the occurrence of depression, as well as less severe manifestations of emotional disturbance, such as lower well-being. Empirical research on these topics strongly and consistently confirms difficulties in emotional functioning among visually impaired elders. In particular, a considerable body of research using different methodologies has shown the prevalence of depression in visually impaired groups to be at least twice as high as that found in normal populations. Social adjustment to vision loss is construed to involve difficulties in social functioning, changes in social support, and loneliness. Although research findings indicate loss of social activity and, to a lesser extent, loss of social support among the visually impaired, the relationship between vision loss and lonelin...
