Figure 2. Example eye position chart demonstrating each of the nine eye positions examined when performing an ocular motility test.

The test conductor observes for abnormal eye movement. As a declarative knowledge test item, the students check the images to determine if a cranial nerve abnormality may be present. In this picture sequence, in the 3 images on the right hand side (where the patient is looking to the left), we see the left eye remains relatively straightforward, rather than shifting away from the nose as would be expected.
