ABSTRACT:
A method of increasing the reliability of visual field testing by preventing intermittent darkening of the visual field during visual field analysis and that is particularly useful in applications of bowl perimetry comprises occluding one eye of a subject, measuring the visual field perception of the unoccluded eye of the subject, while providing sufficient illumination to the occluded eye to eliminate intermittent darkening of the visual field perceived by the unoccluded eye, and while reducing visual acuity in the occluded eye to a level that prevents interference with the visual field testing of the unoccluded eye.
