| Horner's pupil | Constricted pupil due to impairment of sympathetic nerve innervation of the dilator muscle of the pupil. See: Horner's syndrome. (05 Mar 2000) |
| Hutchinson's pupil | Dilation of the pupil on the side of the lesion as part of a third nerve palsy; often due to herniation of the uncus of the temporal lobe through the tentorial notch. (05 Mar 2000) |
| sphincter muscle of pupil | A ring of smooth muscle fibres surrounding the pupillary border of the iris. Synonym: musculus sphincter pupillae, sphincter muscle of pupil. (05 Mar 2000) |
| dilator of pupil | <anatomy> The radial muscular fibres extending from the sphincter pupillae to the ciliary margin; some anatomists regard them as elastic, not muscular, in humans. Synonym: musculus dilator pupillae, dilator iridis, dilator of pupil, musculus dilator iridis. (05 Mar 2000) |
| occlusion of pupil | The presence of an opaque membrane closing the pupillary area. (05 Mar 2000) |
| tadpole-shaped pupil | An intermittent, brief distortion and dilation of a pupil that draws one part of the iris into a peak so that the pupil resembles a tadpole; a temporary, benign condition associated with migraine that may leave the patient with a Horner's syndrome. (05 Mar 2000) |
| tonic pupil | Usually a unilateral abnormality of the eye characterised by slow pupillary constriction to light and in which there is a delayed reaction to changes in accommodation and convergence. The affected pupil is usually larger. (12 Dec 1998) |
| entrance pupil | <microscopy> The apparent size of the limiting aperture of a lens or lens system (properly that of the diaphragm), as seen from the object plane. This can shift and become a complex matter in some circumstances. In a properly set up microscope system it should be that of the substage iris diaphragm. (05 Aug 1998) |
| exclusion of pupil | The condition resulting from posterior annular synechia, in which the iris is bound down throughout the entire pupillary margin, but the pupil is not occluded. Synonym: exclusion of pupil. (05 Mar 2000) |
| exit pupil | <microscopy> The exit pupil of a lens system is an image of the entrance pupil (hence conjugate to it) and normally should be the image of the limiting diaphragm. In both the microscope and the telescope it is the eyepoint where the beam has its smallest cross-section. It is also called the Ramsden circle or eyepoint. (05 Aug 1998) |
| eye-closure pupil reaction | A constriction of both pupils when an effort is made to close eyelids forcibly held apart. A variant of the pupil response to near vision. 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) |
| keyhole pupil | A pupil with a coloboma. (05 Mar 2000) |
| fixed pupil | A stationary pupil unresponsive to all stimuli. (05 Mar 2000) |
