EYE ALIGNMENT MONITOR AND METHOD

摘要

An eye alignment monitor and method are described for the detection of variability of the relative alignment of the two eyes with each other, thereby detecting deficits of binocular function, for use as a screening device for these abnormalities especially in infants and young children. Each embodiment includes means for tracking of the positions of a subject's two eyes simultaneously, and furthermore includes repetitive calculation of the relative positions of the two eyes with respect to each other. The embodiments do not require fixation by either eye on a specific point. Typically, a movie on a video display is used for viewing by the subject. Variability of relative alignment of the two eyes with each other is typically determined by variability of the relative positions of images of the pupils of the eyes with respect to each other over time.

主权项

1. An eye alignment monitor to detect variability of the relative alignment of the two eyes of a subject with each other, comprising:
a stimulus to attract the gaze of said subject; at least one light source for illumination of both eyes of the subject; means for tracking the positions of both eyes simultaneously; and means for repetitive calculation of the relative positions of said both eyes with respect to each other, whereby analysis of changes in the relative positions of said both eyes with respect to each another over time yields a measure of the variability of the relative alignment of the two eyes with each other, for the purpose of detecting deficits of binocular function.
