Resumen
Purpose To assess binocular detection grating acuity using the LEA GRATINGS test to establish age-related norms in healthy infants during their first 3 months of life. Method In this prospective, longitudinal study of healthy infants with clear red reflex at birth, responses to gratings were measured at 1, 2, and 3 months of age using LEA gratings at a distance of 28 cm. The results were recorded as detection grating acuity values, which were arranged in frequency tables and converted to a one-octave scale for statistical analysis. For the repeated measurements, analysis of variance (ANOVA) was used to compare the detection grating acuity results between ages.Results A total of 133 infants were included. The binocular responses to gratings showed development toward higher mean values and spatial frequencies, ranging from 0.55 ± 0.70 cycles per degree (cpd), or 1.74 ± 0.21 logMAR, in month 1 to 3.11 ± 0.54 cpd, or 0.98 ± 0.16 logMAR, in month 3. Repeated ANOVA indicated differences among grating acuity values in the three age groups.Conclusions The LEA GRATINGS test allowed assessment of detection grating acuity and its development in a cohort of healthy infants during their first 3 months of life. © 2014 American Association for Pediatric Ophthalmology and Strabismus. 18 6 563 566 Kaas, J.H., Jain, N., Neural plasticity (2000) Neuroscience Secrets, pp. 373-383. , Wong-Rilley Hanley and Belfus Inc Philadelphia Costa, M.F., Oliveira, A.G.F., Bergamasco, N.H.P., Ventura, D.F., Medidas psicofísicas e eletrofisiológicas da função visual do recém nascido: Uma revisão (2006) Psicol USP, 17, pp. 15-33 Hyvärinen, L., Jacob, N., What and how does this child see?
