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. The inter-rater and test-retest reliability were analyzed with 12 children and the internal consistency with 40 children. RESULTS: Concerning test-retest reliability, six domains exhibited intra-class correlation coefficients ranging from 0.5361 to 1.000. For the movement within surroundings category, this coefficient was 0.37. For inter-rater reliability, only the category of confrontation visual field was below expectations (0.3901). The weighted kappa coefficient exhibited values ranged from -0.087 to 1.000. Cronbach's alfa ranged from 0.584 (movement within surroundings) to 0.973 (contrast sensitivity). CONCLUSION: AVIF-2 to 6 years presented good reliability indexes, however a few items within the domains need minor adjustments in order to improve scores' consistency of some items.
