Quizplus · Accepted Answer

The consensual pupil response is tested by shining a light into one pupil and observing for both pupils to constrict. Observe the corneal light reflex to evaluate for weakness or imbalance of the extraocular muscles. In a darkened room,ask the patient to look straight ahead while a penlight is shone directly on the cornea. The light reflection should be located in the center of both corneas as the patient faces the light source. To perform confrontation visual field testing,the patient faces the examiner and covers one eye and then counts the number of fingers that the examiner brings into the visual field. Instructing the patient to follow a moving object only with the eyes is testing for visual fields and extraocular movements.
