51 Shunt Vessel Meningioma - MRIMeningiomas block venous egress and open potential venous channels known as retinochoroidal (optociliary) collateral vein. This meningioma extends from the back of the globe through the optic canal.Image
52 Stage 2 - PapilledemaImage
53 Stargardt's DiseaseDiscussion of Stargardt's disease, an inherited maculopathy which frequently presents with a loss of central vision.Text
54 Tangent Screen Recording ChartThe tangent screen recording chart.
55 Tangent Screen Testing Visual FieldDescription of tangent screen testing.
56 Third Nerve PalsyPatient with third nerve palsy (no audio)Image/MovingImage
57 Tilted DiscsShort PowerPoint discussion of tilted discs with illustrations and images.
58 Trigeminal Nerve ExamExplanation of a trigeminal nerve exam.
59 Tunnel Vision on Tangent Screen TestingDescription of tunnel vision and tangent screen testing.
60 Vestibular NystagmusExample of patient with vestibular nystagmus. Patient is led through instructions for direction of gaze. Shown also with Frenzel goggles.Image/MovingImage
61 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
62 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
63 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
64 Dissociated NystagmusExample of a patient with dissociated nystagmus. Demonstrates difference in movements between each eye.Image/MovingImage
65 Internuclear Ophthalmoplegia (2 Examples)Two examples of patients with internuclear ophthalmoplegia. First patient has a right internuclear ophthalmoplegia. Patient had subacute bacterial endocarditis with a bacterial abscess in the brain stem. Ductions and gaze to the right look good, but when gazing to the left, the right eye does not ad...Image/MovingImage
66 Latent NystagmusExample of a patient with latent nystagmus. Demonstrates a lack of oscillations in forward gaze, followed by the occlusion of each eye, showing how this generates a jerking oscillation in the non-occluded eye away from the occluded eye.Image/MovingImage
67 OpsoclonusExample of patients with opsoclonus, a saccadic abnormality.Image/MovingImage
68 Paradoxical Constriction of Pupils to Darkness (Flynn Phenomenon)Example of patients both with and without paradoxical constriction of pupils. Observed in many congenital retinal disorders, such as achromatopsia, congenital stationary night-blindness, and Leber's congenital amaurosis. Sometimes seen in optic nerve disorders, such as dominant optic atrophy.Image/MovingImage
69 Parinaud'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...Image/MovingImage
70 Physiologic (End-Gaze) NystagmusDemonstration of physiological nystagmus, where oscillations do not represent pathology, but occur when the patient's gaze is drawn too far laterally.Image/MovingImage
71 Progressive Supranuclear PalsyExample of patient with progressive supranuclear palsy. Discussion of difference between saccadic movement in supranuclear palsy and nystagmus. Shows saccadic intrusions in forward gaze, pursuit, saccades, and doll's head maneuver.Image/MovingImage
72 Spasm of the Near ReflexExample of patient with spasm of the near reflex and voluntary nystagmus. Discussion of similar-looking conditions (e.g. six nerve palsy, limitation of abduction, lateral rectus muscle problems) and how to tell them apart from spasm of the near reflex by observing the myosis evoked by the near respo...Image/MovingImage
73 Transillumination Ocular MelanomaVideo describing condition.Image/MovingImage
74 Upbeat NystagmusExample of a patient with upbeat nystagmus. Shows vertical jerk nystagmus with fast phases in the up direction. Localizes to brain stem, and occurs with strokes, demyelination, and tumors.Image/MovingImage
75 Vestibular NystagmusDiscussion of vestibular nystagmus. Seen with peripheral disorders and central disorders, and in two varieties: spontaneous and positional. Horizontal jerk with small amplitude.Image/MovingImage
