1-4 | 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. | Pupil; Flynn Phenomenon |

 |
2-12 | Periodic Alternating Nystagmus | Example of a patient with periodic alternating nystagmus, showing an alternation between left-beats and right-beats as the patient maintains forward gaze. Nystagmus maintain horizontal direction regardless of position of gaze. | Periodic Alternating Nystagmus |
| 87 |
 |
2-16 | Physiologic (End-Gaze) Nystagmus | Demonstration of physiological nystagmus, where oscillations do not represent pathology, but occur when the patient's gaze is drawn too far laterally. | End-Gaze Nystagmus; Physiologic Nystagmus |
