1.Facial nerve synkinesis - 446KB ( The patient develops a right facial nerve synkinesis after recovering from Ramsey-Hunt' s syndrome. Note the winking of the right eye with mouth movement.
2. Hemifacial spasm - 183KB ( This patient develops a left hemifacial spasm after recovering from a left facial nerve palsy. She is also known to suffer from sarcoidosis. Note the contraction of the facial muscles and eyelid closure. The patient has difficulty in opening the right eye.
3. Blepharospasm - 1,488KB ( This patient complains of a two-year history of recurrent spasmodic contraction of both eyelids which has got worse over the year. Slit-lamp examination of the anterior segment is normal. The spasm is reduced with pre-tarsal botulinum toxin injection.)
4. Mobiussyndrome - 608KB ( The patient has expressionless face and is unable to blow her cheeks or frown. There is poor eyelid closure despite lateral tarsal strips and medial canthoplasties in both eyes. The horizontal eye movement is restricted as shown by the need of the patient to move her
head in order to follow the finger. Vertical eye movement is normal. There is also wasting of the tongue muscles.
5. Mobiussyndrome and Poland's anomaly - 640KB ( The patient has features similar to video 2.
In addition, she has micrognathia and Poland's anomaly which consists of congenital distal limb abnormalities with syndactylism and amputation):
6. Congenital exotropia - 570KB ( The patient has congenital exotropia with visual acuities of 6/60 in the right eye and 6/6 in the left. She had has two previous operation to correct the right exotropia.
Cover tests show bilateral latent nystagmus worse in the right eye. The left eye also shows DVD - dissociated vertical deviation. Ocular motility reveals A-pattern exotropia and right superior oblique
underaction.
7. Partial third nerve palsy - 722KB ( This patient developed a sudden onset right ptosis and diplopia.
The pupil was spared. The third nerve palsy was attributed to her diabetes mellitus.
8. Third nerve palsy - 1,427KB( This patient who suffers from diabetes mellitus and hypertension develops a sudden onset right ptosis. Examination reveals that the right eye has limited movement in those muscles supplied by the third nerve. The pupil is not involved. The appearance is that of a medical thrid nerve palsy.
9. Left fourth nerve palsy - 880 KB(This young girl has a abnormal head posture. The cover/uncover tests are normal with the head tilted. But with the head in the primary position, there is a left over right. Ocular motility shows left inferior oblique overaction and poor depression of
the left eye in adduction.
10. Sixth nerve palsy - 1,066KB ( This patient presents with a sudden onset of diplopia. Examination reveals a right convergent squint caused by a right abducent nerve palsy. Further investigation reveals that he has nasopharyngeal carcinoma.
