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

The test that compares the direct and consensual responses of the pupil is called the pupillary light reflex test. In this test, a light is shone into one eye (the direct response), and both pupils' reactions are observed. The consensual response refers to the constriction of the opposite pupil when light is shone into one eye. This assessment helps evaluate the function of the optic nerve and the pathways involved in the reflex.
