Quantitative assessment of the static properties of the oculo-motor system by the photo-oculographic technique.
The paper addresses the problems raised by the application of the photo-oculographic technique to the quantification of static orientations of the eye in ophthalmology. Eye orientations are determined from the relative positions of corneal reflex and pupil images. The relationship between the positions of these images and the angular rotations of the eye is studied with an optical model of the anterior chamber of the eye. This model is used to analyse the influence of technical and physiological variables and to evaluate the accuracy of different calibration procedures applicable to clinics.
