Which test compares the direct and consensual responses to the pupil?

The Swinging Flashlight Test is designed specifically to assess the direct and consensual pupillary responses. During this test, a light is alternately shined into each eye while observing the reaction of both pupils. This allows the examiner to compare how each pupil reacts when light is directed towards it (the direct response) versus when light is directed to the opposite eye (the consensual response).

An important aspect of this test is that it helps to identify any differences in the function of the optic nerve or any abnormalities in neural pathways associated with the pupillary light reflex. By observing the pupil's reactions during this test, practitioners can assess the integrity of the afferent and efferent pathways involved in this reflex.

Other options, although related to pupillary examination, do not specifically compare direct and consensual responses in the same manner as the Swinging Flashlight Test does.
