The basic eye sensorimotor exam checks the alignment of the eyes and their ability to move together in eight fields of gaze ( up, down, right, left, up–left, up–right, down–left, down–right) and reports them as normal (orthophoria) or as abnormal (with terms tropia, or phorias).
Code 92060 describes a more extensive exam where measurements of ocular deviation are taken in multiple different fields of gaze and at different distances. The patient responds as to whether he sees one object or more than one. It is used in the assessment and follow–up of strabismus (lazy eye). Testing of stereopsis(depth perception) is also performed
