ABSTRACT

In the last few years, research on the development of aids to improve the independence of visually impaired people has increased. The objective of this review was to determine the scientific evidence related to external aids to improve the independence of persons with severe visual impairment or blindness. To carry out the study, PubMed, Cochrane Database-Wiley Online Library, LILACS and Scielo databases were consulted in addition to publications by the World Health Organization, National Institute of Blind People in Colombia, the International Council of Ophthalmology and the preferred patterns in visual rehabilitation practice of the American Academy of Ophthalmology. A total number of 43 articles and documents in English, Portuguese and Spanish were included to be analyzed. Most of the studies were descriptive ones and neither controlled assays nor meta-analysis were found. The observed tendency is the use of technological aids with a user-tailored design and increasingly small, discreet, having many functions that cover the daily life activity of those persons.
