Os efeitos da idade na percepção visual de grades senoidais em luminância baixa
O objetivo deste trabalho foi investigar a função de sensibilidade ao contraste (FSC) de adultos e idosos (20-23, 30-39, 40-49, 50-59, 60-69 anos) para grades senoidais de 0,25 a 2 cpg em luminância baixa. Todos os participantes apresentavam acuidade visual normal e se encontravam livres de doenças...

Abstract | O objetivo deste trabalho foi investigar a função de sensibilidade ao contraste (FSC) de adultos e idosos (20-23, 30-39, 40-49, 50-59, 60-69 anos) para grades senoidais de 0,25 a 2 cpg em luminância baixa. Todos os participantes apresentavam acuidade visual normal e se encontravam livres de doenças oculares identificáveis. Foram estimados limiares de contraste para 30 participantes (seis em cada faixa etária) utilizando o método psicofísico da escolha forçada. Neste método, os participantes tinham que escolher um estímulo contendo uma freqüência de teste (grade senoidal) em baixo contraste ou um estímulo neutro com luminância média de 0,7 cd/m². Os resultados mostraram que os grupos de 50-59 e 60-69 anos apresentaram prejuízos significativos na FSC nas freqüências espaciais de 1 e 2 cpg comparados ao grupo de 20-23 anos. Estes resultados sugerem alterações relacionadas à idade na FSC de freqüências espaciais em níveis baixos de luminância. |
