[Impact of the method choice and the extent of correction on the development of visual evoked potentials in children and adolescents with refractive anomalies].

The article discusses a possible impact of different refraction correction methods, providing full or partial correction, on visual acuity and the development of visual evoked potentials in children and adolescents with myopia and myopic astigmatism. The accuracy of identification of visual evoked potentials depends, as shown in the article, on the extent of the correction chosen and the method used. In childhood the visual system is very susceptible to visual afferent deficit. The permanent deficit of visual information impedes further maturation of the visual analyzer, i.e. the development of central vision, binocular vision, and stereopsis. In high myopia it is important to decide not only on the extent of the correction but also on the method to use. In patients wearing soft contact lenses the visual evoked potentials have more regular shape, amplitude, and latency. The introduction of silicone hydrogel and daily disposal contact lenses, spherical and toric (for astigmatism correction), provided an opportunity to solve hygienic problems associated with contact lens use in children and adolescents and to decrease the risk of hypoxia complications.
