Abstract:
1. A method for observing movement and measuring deviations of an eye using corneal reflex measurements comprising the steps of: a. Directing an infrared light source toward the eye of a subject while the subject looks at a fixation target and wherein the infrared source is aligned or adjacent to the fixation target; b. Covering one eye of the subject with a hand held visually opaque infrared transmitting occluder comprising a handle and an occluding head connected to the handle wherein the occluding head is of a size effective to occlude vision of a fixation target through one eye of a subject; and c. Observing the changes in the deviation of the occluded eye through the visually opaque infrared transmitting occluder via an infrared imaging device and/or recordal of these changes, wherein the occluder, during observing, transmits infrared light and blocks visible light.
