| pupillary membrane | Remnants of the central portion of the anterior layer of the iris stroma (the iridopupillary lamina) which occludes the pupil in foetal life, and normally atrophies about the seventh month of gestation. Persistent strands usually stretch across the pupil from one iris collarette to the other, without touching the pupillary margin. Failure to regress is a rare cause of congenital blindness. Synonym: membrana pupillaris, Wachendorf's membrane. (05 Mar 2000) |
| pupillary reflex | Change in diameter of the pupil as a reflex response to any type of stimulus; e.g., constriction caused by light. Synonym: light reflex. (05 Mar 2000) |
| pupillary ruff | The dark-brown, wrinkled rim of the normal pupil. This is the posterior pigment epithelium of the iris showing itself at the pupillary margin. (05 Mar 2000) |
| pupillary-skin reflex | Dilation of the pupil following scratching of the skin of the neck. Synonym: ciliospinal reflex, cutaneous pupil reflex, cutaneous-pupillary reflex, skin-pupillary reflex. (05 Mar 2000) |
| pupillary zone | The central region of the anterior surface of the iris located between the collarette and the pupillary margin. Synonym: zona pupillaris. (05 Mar 2000) |
| skin-pupillary reflex | Dilation of the pupil following scratching of the skin of the neck. Synonym: ciliospinal reflex, cutaneous pupil reflex, cutaneous-pupillary reflex, skin-pupillary reflex. (05 Mar 2000) |
| indirect pupillary reaction | Contraction of the pupil of the fellow eye in consensus with the pupil of the illuminated eye. Synonym: consensual light reflex, indirect pupillary reaction. (05 Mar 2000) |
| orbicularis pupillary reflex | 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.
