Resumo

O objetivo deste estudo foi comparar curvas de sensibilidade ao contraste para estímulos radiais (FSCr) e grades senoidais (FSC) de 0,25, 0,5, 1 e 2 cpg em crianças de 6 a 13 anos. Foram mensurados limiares de contraste para 40 crianças, utilizando o método psicofísico da escolha forçada e níveis baixos de luminância. Todas estavam livres de doenças oculares e tinham acuidade visual normal. Os resultados mostraram que a sensibilidade das crianças foi maior para grades senoidais (FSC) do que para estímulos radiais (FSCr). Esses resultados sugerem que esses estímulos podem ser processados por áreas visuais distintas.
