| pupillary | 1. Of or pertaining to a pupil or ward. 2. <anatomy> Of or pertaining to the pupil of the eye. Origin: L. Pupillaris: cf. F.pupillaire. See Pupil. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| pupillary axis | A line perpendicular to the surface of the cornea, passing through the centre of the pupil; the "direction of gaze." (05 Mar 2000) |
| pupillary border of iris | The inner border of the iris that forms the edge of the pupil. Synonym: margo pupillaris iridis, pupillary margin of iris. (05 Mar 2000) |
| pupillary dilation | <ophthalmology> The action of stretching or enlarging the pupil for example by atropine. (18 Nov 1997) |
| pupillary distance | The distance between the centre of each pupil; the major reference points in measuring for fitting of spectacle frames and lenses. (05 Mar 2000) |
| pupillary functions, abnormal | Conditions in which the pupil does not react normally to dilation and constriction. Signs of pupillary abnormalities originate from the pupil's shape, position, and response to stimulation. (12 Dec 1998) |
| pupillary light-near dissociation | A stronger near pupil response than light response; due to weak pupillomotor input, Argyll Robertson pupil, dorsal midbrain syndrome, or to misdirection of ciliary muscle fibres into the iris sphincter. Synonym: light-near dissociation. (05 Mar 2000) |
| pupillary margin of iris | The inner border of the iris that forms the edge of the pupil. Synonym: margo pupillaris iridis, pupillary margin of iris. (05 Mar 2000) |
| 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) |
