RAPD Present | This clip demonstrates the technique used to determine that Relative Afferent Pupillary Defect (RAPD) is present in a patient. | Image/MovingImage |
77 |
|
Rebound Nystagmus | Example of a patient with rebound nystagmus, where the oscillations alternate direction as the patient shifts gaze in different directions. Discussion of relationship to disease and disorders of the cerebellum, including degenerations of the cerebellum, infarction, and demyelination. | Image/MovingImage |

Retraction Nystagmus | Patient with retraction nystagmus (no audio) | Image/MovingImage |

|
Rotary Downbeat | Patient with rotary downbeat nystagmus (no audio) | Image/MovingImage |

|
Rotary Nystagmus | Example of a patient with rotary nystagmus, showing occasional counterclockwise rotary movements of both eyes. Seen more in intrinsic disorders of the brainstem. | Image/MovingImage |
81 |
|
Sector Palsies and Light-Near Dissociation | Example 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 |
82 |
|
See-saw Nystagmus | Example 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 |

|
See-saw Nystagmus | 7-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 |
84 |
|
Spasm of the Near Reflex | Example 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 |
85 |
|
Spasmus Nutans | Example 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 |

Spasmus Nutans | Example of patient with spasmus nutans. | Image/MovingImage |

|
Spontaneous Venous Pulsations | This clips shows a spontaneous venous pulsation viewed during an ocular examination. | Image/MovingImage |
88 |
|
Square Wave Jerks | Example of patient with square wave jerks. Discussion of difference between square wave jerks (saccadic oscillations) and horizontal nystagmus. | Image/MovingImage |
89 |

Stereoacuity Testing | Demonstration of examination for stereoacuity. | Text |

Superior Oblique Myokymia | Close-up video of a patient with superior oblique myokymia (no audio.) | Image/MovingImage |
91 |
|
Superior Oblique Myokymia | Example 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 |

|
Third Nerve Palsy | Patient with third nerve palsy (no audio) | Image/MovingImage |
95 |
|
Third Nerve Palsy, Pupil Involving | Example 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 |

|
Tour of the Direct Ophthalmoscope | This 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 |

|
Tour of the Fundus | This clip demonstrates the funduscopic examination technique. | Image/MovingImage |

|
Transillumination - Ciliary Body Neurofibromas | Example of transillumination on a patient with neurofibromatosis, but without Lisch nodules. Shows suspected neurofibromas in the ciliary body. | Image/MovingImage |
99 |
|
Transillumination - Lisch Nodules | Demonstration 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 |
