Tools And Techniques

When young children experience subnormal vision, an array of evaluation tools and techniques is used to assess visual function. Some children who have retinopathy of prematurity may require surgery. Post-operatively, at the Children's Low Vision Center in Boston, the pediatric ophthalmologist evaluates the child's visual functioning using a variety of devices. A tool called the Visual Hand Display has been introduced to enhance the physician's methods of evaluation, thereby achieving greater understanding of the child's visual responses. Collaborations among the doctors, educators, therapists, and patients are emphasized.

Visually Impaired Children

Describes an investigation of how different figure-ground contrast combinations affect the visual functioning of visually impaired children. The study employed the use of field reversals—printing white and yellow foregrounds on a black background—to decrease the amount of light reflected from printed materials to the eye. Eighteen visually impaired children ranging in age from nine years, four months to 14 years, six months participated in this study. The findings indicated that neither reversals in contrast nor chromaticity differences were effective measures for increasing visual functioning.

Retinal Vascular Disease

Retinopathy of Prematurity (ROP) is a retinal vascular disease that affects premature infants and can progress to retinal detachment and blindness. With the increasing survival of premature infants and increased incidence of ROP, it is important to treat patients in a timely manner to preserve their visual function and reduce complications. The purpose of this review is to provide an overview of the recent literature on ROP with a special focus on recent advances in surgical therapy.

The Relationship

Previous research on the relationship between performance of complex tasks and low vision has offered few clear predictors of visual function. In some clinical, screening, and rehabilitation settings, access to measures of vision whose validity extends to the conditions of daily life is limited. The low vision individual may be uniquely qualified to report on such inaccessible performance situations. We have constructed a 57-item questionnaire, administered by interview, designed to predict performance in low vision patients with visual field defects, on four broad categories of visual function: finding, detecting, scanning, and tracking. The finding and detecting categories were further subdivided into subcategories of functional visual field (e.g., finding close, detecting close and above). Subjects rated their experienced degree of difficulty on a wide variety of common tasks which specifically demand these functions. Validity was assessed with 41 subjects. The present study suggests that self-report can be an effective predictor of function, especially in conjunction with clinical psychophysical techniques.
