Question

Quizplus · Accepted Answer

A positive test for pupillary reaction indicates that the afferent pathway from the optic nerve to the brainstem is intact, as well as the efferent pathway from the brainstem to the oculomotor nerve that controls the constriction of the pupil. Therefore, if the test is positive, it rules out optic nerve damage, retinal damage, and oculomotor nerve lesion as the cause of pupillary dysfunction.
