TitleDescriptionType
76 Sector Palsies and Light-Near DissociationExample of patient with bilateral Adie's pupils. Exam is performed with a slit-lamp. Shows iris stroma and focal segments of iris sphincter that retain their contractilty. Suggests post-ganglionic parasympathetic denervation.Image/MovingImage
77 See-Saw NystagmusExample of a patient with see-saw nystagmus, showing how one eye elevates as the other depresses, with the elevating eye intorting as the depressing eye extorts. Shows vertical oscillations with pendular waveforms. Suggests a large structural lesion in the pericellar region (associated with bi-tempo...Image/MovingImage
78 See-Saw Nystagmus7-year-old female whose mother noticed her eyes "bouncing" for 2 months. Visual acuity 20/70 OD and 20/40 OS, reduced color vision OU, and no afferent pupillary defect. See-saw nystagmus documented with videography. Manual perimetry revealed a complete right homonymous hemianopia. MRI revealed a lar...Image/MovingImage
79 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
80 Spasmus NutansImage/MovingImage
81 Spasmus NutansExample of patient with spasmus nutans. Discussion of characteristics of this disorder, such as dissociated or monocular nystagmus, abnormal head position, and to-and-fro head oscillation. Sometimes an eccentric gaze is seen as well (as in patient). Patient has a monocular horizontal nystagmus in th...Image/MovingImage
82 Spontaneous Venous PulsationsThis clips shows a spontaneous venous pulsation viewed during an ocular examination.Image/MovingImage
83 Square Wave JerksExample of patient with square wave jerks. Discussion of difference between square wave jerks (saccadic oscillations) and horizontal nystagmus.Image/MovingImage
84 Superior Oblique MyokymiaExample of patients with superior oblique myokymia, a saccadic intrusion. First patient is seen to have intermittent, intorting movements with superimposed slight vertical deviations in right eye. Discussion of disorder as benign, but frequently disabling, as patients experience episodes of diplopia...Image/MovingImage
85 Superior Oblique MyokymiaImage/MovingImage
86 Testing the Visual FieldsDemonstration of various methods of testing visual fields, including counting fingers, motion, and color of several objects.Image/MovingImage
87 Third Nerve PalsyPatient with third nerve palsy (no audio)Image/MovingImage
88 Third Nerve Palsy, Pupil InvolvingExample of patient with third nerve palsy. Left eye shows pupilary involvement. Left eye doesn't immediately duct, but abducts well, with impaired superduction. Secondary and primary deviations are demonstrated. Anisocoria is more prominent when light is on, showing a parasympathetic defect to the p...Image/MovingImage
89 Tour of the Direct OphthalmoscopeThis clip describes the parts and operation of the ophthalmoscope as an ocular examination tool. Includes adjustment of aperture size and adjustment of lenses.Image/MovingImage
90 Tour of the FundusThis clip demonstrates the funduscopic examination technique.Image/MovingImage
91 Transillumination - Ciliary Body NeurofibromasExample of transillumination on a patient with neurofibromatosis, but without Lisch nodules. Shows suspected neurofibromas in the ciliary body.Image/MovingImage
92 Transillumination - 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...Image/MovingImage
93 Transillumination Ocular MelanomaVideo describing condition.Image/MovingImage
94 Ultrasonography TechniquesThis video describes and demonstrates the various techniques for examination of the eye using ultrasonography, including A-scan, B-scan and immersion.Image/MovingImage
95 Ultrasonography: Immersion TechniqueThis video describes and demonstrates the immersion technique for examination of the eye using ultrasonography.Image/MovingImage
96 Unilateral BlepharospasmExample of patient with unilateral blepharospasm.Image/MovingImage
97 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
98 Vestibular NystagmusExample of patient with vestibular nystagmus. Patient is led through instructions for direction of gaze. Shown also with Frenzel goggles.Image/MovingImage
99 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
100 Voluntary NystagmusExample of patient with voluntary nystagmus. Discussion of how a lack of uniform, patterned movement of the eyes along with associated lid movements suggests that activity is voluntary.Image/MovingImage
