Synonym: Galassi's pupillary phenomenon, Gifford's reflex, lid-closure reaction, orbicularis phenomenon, orbicularis pupillary reflex, Piltz sign, Westphal's pupillary reflex, Westphal-Piltz phenomenon. (05 Mar 2000) |
| paradoxical pupillary phenomenon | A pupillary response to light, the reverse of that expected; e.g., contraction of the pupil in response to turning the lights off. Synonym: Flynn phenomenon, paradoxical pupillary phenomenon. (05 Mar 2000) |
| paradoxical pupillary reflex | A pupillary response to light, the reverse of that expected; e.g., contraction of the pupil in response to turning the lights off. Synonym: Flynn phenomenon, paradoxical pupillary phenomenon. (05 Mar 2000) |
| reflex, pupillary | Constriction of the pupil in response to light stimulation of the retina. It refers also to any reflex involving the iris, with resultant alteration of the diameter of the pupil. (12 Dec 1998) |
| relative afferent pupillary defect | An asymmetry of the pupillomotor input between the two eyes; tested by alternating the light from one eye to the other and comparing the direct light reactions. (05 Mar 2000) |
