SUMMARY
Visual fields were measured monocularly in 8 meridians (vertical-horizontal and orthogonal diagonal at 45 degrees) with kinetic doublearc perimetry in a group of 43 children aged from 2 to 12 months divided in two age groups: Group l - children from 2-6 months old (n = 24, mean = 4 months) and Group II - chiben from 7-12 months old (n = 19, mean = 8.5 months.), lnclusion criteria were: normal fundus, no significant refractive errors, normal grating visual acuity measured by Teller Acuity Cards, normal ocular motility and absence of ocular and/or neurological disorders. Monocular visual fields from Group l were constricted but presents the same shape as that of the adult. In Group II constriction was restricted to the three temporal meridians and to the inferior one, while the remaining meridians had already reached adult values. In both groups the temporal hemifield was larger than the nasal one. Possible factors involved in the maturation of visual fields in normal children could be anatomic (retina, photoreceptors, neural) as well as attentional mechanisms.
