1 2-37a - Vascular FeaturesWhen looking at the disc, the central retinal artery and vein should be visible. The central retinal artery is usually slightly narrower than the vein. When the central retinal artery goes though the lamina cribrosa, the artery becomes smaller because of diminution of the muscular layer and loss of ...Image

3 2-4a - Disc AnatomyThe optic disc appearance is determined by: the size of the eye, the size of the scleral canal, how the nerve is inserted into the globe, the appearance of the lamina cribrosa, where myelination stops, and what is left behind in normal development. Even though this is a disc with a very large cup, i...Image
4 2-53a - Venous PulsationsOn the disc, look for spontaneous venous pulsations. Spontaneous venous pulsations can be seen in the large trunks of veins at the level of the disc margin. They are normally present and seen in 37-90% of normals -- depending on the experience of the examiner and the shape of the disc. The spontaneo...Image

6 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. Disease/Diagnosis: Abducting NystagmusImage/MovingImage
7 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
8 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
9 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
10 Aberrant Regeneration of the Third and Sixth NervesImage/MovingImage
11 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
12 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
13 Bilateral Facial MyokymiaExample of a patient with a brain stem glioma. Shows bilateral facial myokymia.Image/MovingImage
14 Bilateral Internuclear OphthalmoplegiaExample of patient with bilateral internuclear ophthalmoplegia. Patient is led through instructions for direction and distance of gaze.Image/MovingImage
15 Bilateral PtosisVideo of patient with bilateral ptosis.Image/MovingImage
16 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
17 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
18 Blepharospasm with Apraxia of the EyeImage/MovingImage
19 Brainstem TraumaImage/MovingImage
20 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

23 Cogan's Lid TwitchImage/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
