A confrontational test for visual fields assesses the optic nerve function by measuring the peripheral visual field of each eye. This test evaluates the ability of the optic nerve to transmit visual information from the eye to the brain. Applying a cotton wisp strand to the cornea assesses the function of the trigeminal nerve (cranial nerve V). Evaluating pupil response to light and accommodation assesses the function of the oculomotor nerve (cranial nerve III). Asking the patient to follow a finger with the eyes assesses the function of multiple cranial nerves, including the oculomotor, trochlear (cranial nerve IV), and abducens (cranial nerve VI) nerves, but does not specifically assess the function of the optic nerve.
