Instruments for evaluation of functionality in children with low vision: a literature review.

We conducted a literature review of tools used to evaluate functionality in children with low vision with the aim of analyzing the applicability, advantages, and disadvantages for children <6 years of age, an age at which visual development is mostly complete. Publications in Portuguese, English and, Spanish describing functional evaluation tools for children aged 0-18 years with low vision in the following databases were included: Web of Science, Virtual Health Library, Cochrane, Scielo, and PubMed. A total of 181 articles were collected, 15 of which were included in this review.

[Reliability of functional vision assessment in children with low vision from 2 to 6 years old--searching for evidences].

Purpose: The functional vision assessment (AVIF-2 to 6 years) for low vision children with ages from 2 to 6 years old was analyzed. The inter-rater, test-retest and the internal consistency were verified for reliability.

Methods: The test, composed by seven domains (visual fixation, visual following, visual field confrontation, eye-hand coordination and surrounding locomotion, contrast vision and color vision discrimination), was applied to 40 children, 20 with low vision and 20 without low vision.

[Functional vision assessment in children with low vision from two to six years of age - a comparative study].

Purpose: The Functional Vision Assessment (AVIF-2 to 6 years)'s capacity to differentiate visual ability levels in children with low vision was analyzed. The AVIF-2 to 6 years was created at the Infantile Low Vision Sector from São Geraldo Hospital, Brazil.

Methods: After a debate among professionals from different areas regarding the appropriateness of the test items, AVIF-2 to 6 years was applied to 40 children aged from 2 to 6 years; twenty children with low vision (Group 1) and twenty without it (Group 2) were assessed.
