Generally, versions are tested first; both eyes’ movements into the 9 diagnostic positions of gaze are assessed. Limitations of movement and asymmetric excursion of the 2 eyes (such as “overaction”) are noted. Spinning the child or the doll’s head maneuver may be used to elicit vestibular-stimulated eye movements. If versions are not full, the examiner should test duction movements for each eye separately (Video 7-6). BCSC Section 5, Neuro-Ophthalmology, also discusses testing of the ocular motility system.
