Abstract

Dispositivo y método que permite obtener una medida objetiva del tamaño y patrón morfológico de la degradación de la imagen en visión escotópica, consistente en una pantalla frontal negra (1) que consta de una fuente luminosa central (2) circundada por una rejilla de spots luminosos circulares (3) que al inicio del test se iluminan secuencial o aleatoriamente, según el modo seleccionado, desde el más próximo a la fuente central de deslumbramiento de forma centrífuga hacia el más periférico, y un mando de accionamiento que pulsará el paciente inducido a hacerlo cada vez que sea capaz de discriminar la presencia de cada uno de los spots en los 12 meridianos, quedando delimitada por los spots no discriminados u ocultos, un área que se interpreta ocupada por la aberración luminosa y que sirve de base para el cálculo del índice de deslumbramiento.
