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 phot o-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 relationshi p between the positions of these images and the angular rotations of t he 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 phy siological variables and to evaluate the accuracy of different calibra tion procedures applicable to clinics.
