[Evaluation of patients using an innovative low-vision aid]

Abstract

Purpose: To perform a preliminary evaluation at the "Clínica Oftalmológica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (USP)" of an innovative equipment for low-vision developed at USP containing a reading stand and a magnifier that maintains in a stable position the reading line and focus.

Methods: 9 low-vision patients were evaluated using the above mentioned reading stand and a magnifier developed at USP comparing it with a hand magnifier of similar power taking into account the following evaluation parameters: etiology of low-vision, best corrected visual acuity for distance, patient's opinion comparing both low-vision aid resources, authors' opinion observing the patient using both low-vision aids.

Results: The numerical preference for the low-vision aids was: 5 patients for the reading stand and a magnifier that maintains at a stable position the reading line and focus; 2 patients for the hand magnifier; 1 patient indifferent regarding any of the resources; 1 patient inadequate for the evaluation of the low-vision aids.

Conclusion: This preliminary study shows the preference of the majority of the patients for the reading stand and a magnifier that maintains at a stable position the reading line and focus showing that this innovative product makes reading easier; the evaluator doctor translates the patient's opinion as an expert and contributes to the improvement of the product so that it can be evaluated again in the future.
