Refractive state in children less than one year of age

Abstract

The refractive estate is described in pediatrically normal infants under 12 months of age. The infants that were examined came from the Hospital Tunjuelito‐ Clinical El Carmen population, who participated in the “Growth and development program” Refraction was measured by dynamic retinoscopy. The most common refractive states found were: Astigmatism (77% RE, 73.5% LE)with the rule (100% RE, 97.4% LE) hipermetropic in both meridians or hipermetropic and myopic. The positive and negative spherical component in the right eye fluctuated between 0.25 – 1.50 diopters; in the left eye the positive was 0.25 – 0.75 and the negative 1.00 – 1.50 diopters. The cylindrical magnitudes were below 2.50 diopters RE, 3.00 diopters LE (73.8% RE, 66.6% LE). The anisometropic values were low; only 1 infant was 2.50 diopters anisometropic.
