1Department of Physiology, University of Helsinki, Finland.
Insights
Comprehensive vision evaluations are crucial for habilitating children with visual impairments. A multidisciplinary team approach utilizing play-based assessments ensures thorough understanding of visual capabilities and limitations.
Area of Science:
- Ophthalmology
- Pediatric Vision Science
- Rehabilitation Medicine
Background:
- Effective habilitation for visually impaired infants and children requires a deep understanding of their specific visual abilities and challenges.
- Current practices emphasize the need for comprehensive visual function assessments.
Purpose of the Study:
- To outline the essential components of a comprehensive visual function evaluation for children with visual impairments.
- To highlight the importance of a multidisciplinary team approach and play-based assessments.
Main Methods:
- Measurement of key visual functions including visual acuity, contrast sensitivity, visual field, color vision, adaptation, visual sphere, accommodation, and oculomotor functions.
- Integration of assessments within play situations for ease of use with children.
- Inclusion of evaluation of motor function's impact on vision utilization.
Main Results:
- A comprehensive evaluation can effectively measure nearly all aspects of a child's vision using accessible, play-based tests.
- A team-based approach involving therapists, special educators, and physicians is optimal for thorough assessment.
- Potential need for additional training for non-physician team members on optics and optical devices.
Conclusions:
- Thorough visual assessments are fundamental for successful habilitation programs in children with visual impairments.
- A multidisciplinary, play-based evaluation strategy is effective and recommended.
- Ongoing education for all team members enhances the accuracy and comprehensiveness of visual assessments.
Abstract:
Habilitation of infants and children with visual impairments should be based on a thorough understanding of their visual capabilities and limitations. Comprehensive evaluation of visual function includes measurement of visual acuity, contrast sensitivity, visual field, color vision, adaptation, visual sphere, accommodation, and oculomotor functions. It is best completed through a team approach that uses therapists, special educators, and physicians. A complete evaluation also includes examination of the effect of other motor functions on the use of vision. Nearly all aspects of a child's vision can be measured in play situations with tests that are easy to use. However, further education of nonphysician team members in refractive errors, optics, and function of optical devices may be necessary to ensure an accurate and thorough evaluation.
