2 A-scan TechniqueThis video describes and demonstrates the A-scan examination technique for examination of the eye using ultrasonography.Image/MovingImage
3 Abducting (Dissociated) NystagmusExample of a patient with abducting (dissociated) nystagmus. Patient has a subtle internuclear ophthalmoplegia. Right eye has right-beating jerk nystagmus, with smaller oscillations in the left eye.Image/MovingImage
4 Aberrant Regeneration of the LidPatient with left third nerve palsy demonstrates anisocoria and mild vertical gaze limitation and aberrant movement of the left upper lid. Patient is instructed through all gaze positions. Left upper lid does not descend during downgaze but retracts instead.Image/MovingImage
5 Aberrant 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.Image/MovingImage
6 Aberrant Regeneration of the ThirdPatient with a right third nerve palsy demonstrates ptosis, anisocoria and ophthalmoplegia. During attempted downgaze, the right upper lid flutters back up (aberrant movement) and remains retracted.Image/MovingImage
7 Aberrant Regeneration of the Third and Sixth NervesImage/MovingImage
8 Aberrant Regeneration of Third Nerve, Bilaterally (1 degree OD, 2 Digrees OS)Example of patient with bilateral aberrancy of the third nerve. Shows lids popping up (synkinetic) with adduction. Patient had bilateral internal carotid artery aneurisms with third nerve compression.Image/MovingImage
9 B-scan TechniqueThis video describes and demonstrates the B-scan examination technique for examination of the eye using ultrasonography.Image/MovingImage
10 Before 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 ...Image/MovingImage

12 Bilateral Facial MyokymiaExample of a patient with a brain stem glioma. Shows bilateral facial myokymia.Image/MovingImage
13 Bilateral Internuclear OphthalmoplegiaExample of patient with bilateral internuclear ophthalmoplegia. Patient is led through instructions for direction and distance of gaze.Image/MovingImage
14 Bilateral PtosisImage/MovingImage
15 Binocular Pendular NystagmusExample of a patient with binocular pendular nystagmus. Patient has somewhat dissociated nystagmus, with nystagmus seen more prominently in the left eye. Patient shows an occasional jerk nystagmus to the right in the right eye. Left eye oscillations are mostly pendular.Image/MovingImage
16 BlepharospasmExample of patient with blepharospasm. Patient is led through instructions for direction of gaze and opening and closing of eyes. Patient is led through same exercises again after receiving indomethacin treatment.Image/MovingImage
17 Blepharospasm with Apraxia of the EyeImage/MovingImage
18 Brainstem TraumaImage/MovingImage
19 Brun's NystagmusObservation of patient with Brun's Nystagmus. Shows patient gazing to the right and the nystagmus beating in the direction of the gaze.Image/MovingImage

24 Congenital NystagmusExample of patients with congenital nystagmus. First patient's nystagmus are mostly jerk and not pendular. Second patient's nystagmus are mostly pendular. Both patients show a uniform horizontal oscillation. Second patient also shows differences in frequency of oscillations depending on gaze, includ...Image/MovingImage
25 Congenital 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.Image/MovingImage
