Abstract

GAGLIARDO, Heloisa G.R. Gardon; GONCALVES, Vanda M. Gimenes  and  LIMA, Maria Cecília Marconi Pinheiro. A method to evaluate visual ability in infants. Arq. Neuro-Psiquiatr. [online]. 2004, vol.62, n.2a, pp. 300-306. ISSN 0004-282X.  http://dx.doi.org/10.1590/S0004-282X2004000200020.

The purpose of this study is to introduce a method to evaluate visual functions in infants in the first three months of life. An adaptation of the Guide for the Assessment of Visual Ability in Infants (Gagliardo, 1997) was used. The instrument was a ring with string. It was implemented a pilot study with 33 infants, selected according to the following criteria: neonates well enough to go home within two days of birth; 1 to 3 months of chronological age; monthly evaluation with no absence; subjects living in Campinas/SP metropolitan area. In the first month we observed: visual fixation (93,9%); eye contact (90,9%); horizontal tracking (72,7%); inspects surroundings (97,0%). In the third month, we observed: inspects own hands (42,4%) and increased movements of arms (36,4%). This method allowed the evaluation of visual functions in infants, according to the chronological age. Alterations in this function will facilitate immediate referral to medical services for diagnoses.
