Influencia de la iluminación en la medida de la agudeza visual

Abstract

En este estudio de campo , se ha analizado si la iluminación ambiental interfiere en los resultados obtenidos en la agudeza visual , tanto en condiciones monoculares como binoculares, con y sin corrección , en visión lejana. Para poder llevar lo a cabo, se escogió una muestra de trein ta sujetos, entre ellos había diez pacientes miopes, diez hipermétropes y diez emétropes , con edades comprendidas entre 20 y 25 años. Se dispuso el gabinete en tres condiciones distintas de iluminación ambiental, fotópicas (400 lux), mesópicas (200 lux) y escotópicas (10 lux) , que era el menor nivel de iluminación que podía acondicionarse en el gabinete con el optotipo encendido. Todas estas condiciones fueron medidas con el luxómetro. De igual manera , se utilizó el test ETDRS , para poder determinar las agu dezas visuales alcanzadas por los distintos pacientes y condiciones de iluminación, éste test se disponía siempre con la luminancia de fondo que poseía , y con la misma intensidad de color de los caracteres del optotipo. A partir de los valores de agudeza v isual obtenidos , y mediante la elaboración de un análisis estadístico , se concluyó que la agudeza visual sí se encuentra influenciada por la iluminación ambiental del gabinete.
