5 1-13Spasm of the Near ReflexExample of patient with spasm of the near reflex and voluntary nystagmus.

8 1-15bOpsoclonusExample of patients with opsoclonus, a saccadic abnormality.Opsoclonus
9 1-16Parinaud's SyndromeTwo examples of patients with Parinaud's syndrome, a dorsal midbrain syndrome. Discussion of hallmarks of this syndrome, including convergence retraction nystagmus, vertical gaze palsies, light-near dissociation, and Collier's Sign. Discussion of age-dependent disorders associated with this syndrome...Parinaud's Syndrome; Dorsal Midbrain Syndrome
10 1-17Congenital Ocular Motor ApraxiaTwo examples of congenital ocular motor apraxia. Patients have trouble initiating saccades, and compensate with head movement. Discussion of how to distinguish this condition from simply not seeing well.Congenital Ocular Motor Apraxia
11 1-18Hemifacial SpasmExample of patients with hemifacial spasm. First patient has a sequela of Bell's palsy, and is seen to have mainly clonic movements around the eye, with occasional tonic movements around the mouth. Second patient has a cerebellopontine angle epidurmoid tumor, and is seen to have movements around the...Hemifacial Spasm
12 1-19Aberrant Regeneration of the Seventh NerveExamples of patients with aberrant regeneration of the seventh nerve. First example is a patient with contractions around the mouth and dimpling, demonstrated with slow and rapid eye blinking. Second example shows contraction around nose with eye blink.Aberrant Regeneration of the Seventh Nerve; Aberrant Regeneration
13 1-2Dilation LagTwo examples of dilation lag (Horner's syndrome). In the first example, the right pupil dilates much faster than the left pupil when the light is turned out. In the second example, the left pupil dilates much faster than the right pupil when the light is turned out. Discussion of methods of document...Dilation Lag; Horner Syndrome; Horner's Syndrome
14 1-20Facial Myokymia UnilateralExample of patient with facial myokymia, a disorder of the seventh nerve, probably due to brain stem involvement. Patient has multiple sclerosis. Discussion of characteristics, such as continuous, undulating, contractions in the distribution of the seventh nerve, and a spreading of these movements t...Superior Oblique Myokymia; Facial Myokymia Unilateral; Facial Myokymia
15 1-21Bilateral Facial MyokymiaExample of a patient with a brain stem glioma. Shows bilateral facial myokymia.Bilateral Facial Myokymia; Facial Myokymia

Shows split-scr...Ocular Myasthenia; Myasthenia Gravis; Ptosis, Myasthenic; Tensilon Test
18 1-24Before TensilonExample of patient with myasthenia gravis. Demonstration of baseline examination, followed by administration of 2mg of tensilon, which is a test dose. Procedure for administration of tensilon test is described, including variations. Patient is then shown after being given 4mg of tensilon, with very ...Myasthenia Gravis; Tensilon Test
19 1-25Cogan's Lid TwitchExample of a patient with Cogan's lid twitch, with discussion of how to detect it in an exam.Cogan's Lid Twitch; Lid Twitch
20 1-26Levator DisinsertionExample of patient with levator disinsertion, a lid disorder. Patient is pregnant and wears poorly fitting contacts. Discussion of characteristics, such as lid ptosis (shown in the left eye of patient), but with full levator function.Levator Disinsertion; Levator Dehiscence

22 1-29Transillumination - Lisch NodulesDemonstration of transillumination of the Lisch nodules on a patient with neurofibromatosis. Shows how Lisch nodules that were not very visible in slit-lamp examination are better seen with transillumination, which may therefore be useful in detecting Lisch nodules earlier in children where they are...Transillumination; Examination, Ocular; Lisch Nodules; Neurofibromatosis1
