11. Marcus-Gunn's
jaw-winking ptosis 236KB ( This baby has
a right ptosis. The jaw-winking was
brought out by her suckling the bottle)
12. Right Duane's
Syndrome 937KB ( The
patient has an abnormal head posture with head turn to the
right.Eye movement shows limited right abduction and narrowing of the palpebral
fissure on adduction.
He has a right Type I Duane's syndrome.)
13. Bilateral
Duane's Syndrome 716KB (
The patient has an abnormal head posture with chin
depression. Eye movement reveals bilateral limited abduction with narrowing
of the palpebral fissure on
adduction. Bilateral up-shooting of the eyes on adduction are seen being
more marked on the left than
right. He has bilateral Type 1 Duane's Syndrome.)
14. Thyroid eye disease..808KB
( The patient has a right proptosis and hypotropia secondary to thyroid
eye disease. Eye movement shows poor elevation of the right eye and lid
lag on downgaze.)
15. Pendular
nystagmus 997KB ( This baby suffers
from oculocutaneous albinism. The video shows
pendular nystagmus in the primary position.)
16. Periodic
alternating nystagmus 2,482KB ( The patient
has periodic alternating nystagmus. The
video shows the presence of jerky nystagmus in the primary position; the
fast component is initially
to the left, followed by a short rest period of about 5 seconds, then slowly
the eyes develops
jerky nystagmus with the fast component to the right. The cycle is then
repeated with a rest period and
then jerky nystagmus to the left. This type of nystagmus may be congenital
or secondary to cerebellar
disease such as CVA or multiple sclerosis.)
17. Parinaud's
syndrome 730KB ( The video shows failure
of the pupils to respond to light but on
attempted convergence, which is incomplete because the patient has
paresis of convergence, the pupils
constrict. The eyes show convergence retraction nystagmus best seen with
a down-going opticokinetic
drum.)
18. See-saw
nystagmus 755KB ( This
patient has see-saw nystagmus characterised by supraduction and
intortion of one eye, and infraduction and excyclotortion of the other.
This coniditon is seen in
suprasellar lesion and bitemporal hemianopia is common.)
19. Upbeat
nystagmus 1,463KB (This patient has an upbeat
nystagmus in the primary position and a right
skew devation (the right eye shows a vertical deviation as well as being
exotropic). This type of
nystagmus is seen in patient with a brainstem lesion such as multiple
sclerosis. The exact location is
uncertain.)
20. Downbeat
nystagmus 782KB (The presence of downbeat
nystagmus suggests a lesion in the
cervicomedullary junction. Causes include Arnold-Chiari's syndrome, spinocerebellar
degeneration, stroke
and multiple sclerosis.)
