Trauma To The Face Flashcards
swinging flashlight test is for
Check the swinging flashlight test for evidence of an afferent papillary defect (Marcus Gunn pupil).
With normal function, the swinging light results in brief dilation during movement followed by constriction when the light is directly over the eye.
With injury to the optic nerve or retina, the affected pupil will not constrict until the light is again moved to the unaffected eye.
The test is sensitive but not specific for optic nerve injury, because an afferent papillary defect may result from pathology anywhere along the visual pathway.
