Measurement of head-turn in ocular torticollis.
There is a need for a simple and accurate method to measure head-turn in patients who suffer from torticollis secondary to ocular disease. In the technique described here, a fixation object is moved from a point in front of the patient to a point at which the patient's face is straight. The distance that the object is moved is proportional to the amount of head-turn the patient has. With a simple mathematical calculation, the angle of head-turn can be determined, even during a routine clinical evaluation.
