La sensibilidad al contraste (SC) evalúa la capacidad visual de un individuo expuesto a diferentes niveles de contraste. Una disminución de la misma puede ser indicativa de patología ocular como la ambliopía. Existen actualmente diferentes test de medida de la SC, siendo el objeto de este estudio analizar la repetibilidad de Visionary en comparación con el CSV-1000.
Se realizaron 3 medidas de SC con Visionary y 1 con CSV-1000, en 26 voluntarios que participaron en el estudio, todos ellos sin problemas patológicos que pudieran afectar a su SC y con su corrección necesaria para alcanzar Agudeza visual (AV) superior a 0,8.
Contrast sensitivity (CS) assesses the visual function capacity of a person exposed to different levels of contrast. A decrease may indicate ocular pathology, such as amblyopia. There are different CS measuring devices, the purpose of this study is to analyze the repeatability of Visionary and agreement to the CSV-1000.
It was made 3 Visionary measurements and 1 CSV-1000 test, in this order: One from Visionary, one from CSV-1000 and then two consecutive from Visionary, in 26 patients who participated in the study, all of them without pathological problems related to CS and with its necessary correction to reach AV higher than 0,8.
