This can be demonstrated with the swinging flashlight test, in which the light is moved back and forth between the eyes every two to three seconds. The afferent pupillary defect becomes obvious when the flashlight is moved from the normal to the affected eye, and the affected pupil dilates in response to light. If an optic nerve lesion is present the affected pupil will not constrict to light when light is shone in the that pupil during the swinging flashlight test. However, it will constrict if light is shone in the other eye (consensual response). Each of the patients showing a positive swinging flashlight test had mild unilateral optic nerve pallor. The results further indicate that in mild optic nerve damage, a positive swinging flashlight test is more consistently present than a color vision deficit or a demonstrable visual field scotoma.
