Sensibilidad al Contraste Acromático para Redes Sinusoidais Vertical en Adolescentes y Adulto
Contenido principal del artículo
Resumen
El objetivo de este estudio fue caracterizar la función de sensibilidad al contraste (FSC) de los adolescentes y adultos jóvenes. Se midió la FSC para estímulos de onda senoidal con frecuencias espaciales lineal de 0,25, 1,0, 2,0 y 8,0 cpg, utilizando el método psicofísico de la elección forzada con dos alternativas. Las mediciones se realizaron con la visión binocular y la luminancia media del 42,6 cd/m2. Todos los participantes presentaban acuidad visual normal y estaban libres de enfermedades oculares identificables. El análisis mostró diferencias significativas entre los dos grupos en las frecuencias de bajo, medio y alto. Los adultos eran más sensibles que los adolescentes en las frecuencias bajas (0,25 cpg) y los adolescentes eran más sensibles que los adultos en las frecuencias medias y altas (2,0 y 8,0 cpg). Estos resultados sugieren que el proceso de desarrollo y maduración de la percepción visual de contraste interactúa de manera diferente con los mecanismos que las frecuencias de proceso espacial.
