b.Hyperacusis of the left ear
The corneal reflex is tested by touching a cotton wisp to the eye. A normal response would be blinking of the ipsilateral eye as well as the contralateral eye ( consensual reflex). The afferent limb of the corneal reflex is contained within the ophtalmic division of the ipsilateral of the ophtalmic nerve(V1), the efferent limb is by both (right and left) facial nerves (VII).
This woman had a normal corneal reflex in her right eye, indicating a normal right V1 an right VII. However, she lacked a consensual reflex, indicating an abnormal left VIIth nerve.
A lesion in the left VIIth nerve would also produce HYPERACUSIS (increased sensitivity to sound) in the left ear because of paralysis of the STAPEDIUS muscle, which ordinarily dampens sound transmission through the middle ear.
