The ocular torticollis is a forced position of the head taken due to visual difficulties. It happens, therefore, that the person spontaneously rotates the head in an attempt to improve the visual function and to obviate the consequences of the deviation of the gaze, such as diplopia (double vision) and nystagmus.
An abnormal rotation or inclination of the head can be found in the uncomfortable strabismus, in the nystagmies, in the oculomotor paralysis and in the badly corrected defects of refraction.
