Emily’s mum, stick to your guns. There are 12 cranial nerves supplying the facial area, numbers III. IV, & VI supply the muscles moving the eyeball, there are six muscles to each eye. Between 5 and 30% of patients with CIDP have cranial nerve involvement, Emily cannot move her eye to one side because there is a palsy of the lateral rectus muscle on that side. This is a squint, the risk is a lazy eye where one eye stops accepting visual messages so as not to confuse the brain with double vision. You are right to cover one eye,,alternate between the two eyes until you see the ophthalmologist.
