Which test is used to compare direct and consensual responses to the pupil?

The Swinging Flashlight test is indeed the correct choice for comparing direct and consensual responses of the pupils. This test assesses how each pupil reacts when a light is shone in one eye compared to when it's shone in the other.

During the procedure, a light is moved back and forth between the two eyes, allowing the examiner to observe both the direct response (the pupil constricting in the eye receiving the light directly) and the consensual response (the pupil of the opposite eye constricting as well). A normal response indicates proper functioning of the optic and oculomotor nerves, as well as the pathways involved.

In contrast, other tests listed focus on different aspects or do not specifically compare pupil responses. The Acoustic Reflex involves testing the reflexive contraction of muscles in the middle ear in response to loud sounds, which does not pertain to pupil response. A Pupilometer is a device that measures the diameter of the pupils but does not test their responses directly. The Flashlight Reflex is similar in concept but does not have the comparative element that the Swinging Flashlight test provides.

Thus, the Swinging Flashlight test serves as a crucial clinical tool for assessing neurological function related to pupils.
