Abstract

The literature mentions several invasive methods to measure the degree of the compensatory torsional eye movement during a head-tilt. Nevertheless, none of them have yielded universally clinical tests. This study focuses on an optical system (with a circular polarizer) for noninvasive acquisition of corneal birefringence patterns (isochromes). The acquired isochromes are quadrangular in shape and unique for each eye, as well as independent of the head-rotation angle. The results obtained suggest that isochrome orientation analysis could be an effective method to accurately measure the degree of compensatory torsional eye movement.
