[Binocular three-dimensional video-oculography].
BACKGROUND
It has long been a goal to develop a means to measure squint angles in three dimensions simultaneously. A three-dimensional binocular method is naturally needed especially with surgical procedures that affect three dimensions of ocular motility.


METHODS
Special modifications of a videographic method provide simultaneous online data on the three-dimensional position of the eyes. The interocular difference is equal to the amount of squint, depending on the direction of gaze, head-tilt/direction of gravity, and convergence.


RESULTS
The method introduced provides three-dimensional and binocular documentation of ocular movements. This could lead to improved pre- and postsurgical examination, especially of rotational disturbances, and it could also offer an objective means for comparing the results of various surgical procedures.
