| margo pupillaris iridis | The inner border of the iris that forms the edge of the pupil. Synonym: margo pupillaris iridis, pupillary margin of iris. (05 Mar 2000) |
|---|
| margo ciliaris iridis | The peripheral border of the iris attached to the ciliary body. Synonym: margo ciliaris iridis, ciliary margin of iris. (05 Mar 2000) |
|---|---|
| membrana pupillaris | 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) |
| zona pupillaris | The central region of the anterior surface of the iris located between the collarette and the pupillary margin. Synonym: zona pupillaris. (05 Mar 2000) |
| angulus iridis | The acute angle between the iris and the cornea at the periphery of the anterior chamber of the eye. Synonym: angulus iridocornealis, angle of iris, angulus iridis, filtration angle. (05 Mar 2000) |
| annulus iridis | Either of two zones on the anterior surface of the iris, separated by a circular line concentric with the pupillary border. Synonym: annulus iridis. (05 Mar 2000) |
| annulus iridis major | The outer, broader of the two zones of the iris. Synonym: annulus iridis major. (05 Mar 2000) |
| annulus iridis minor | The narrow inner zone of the iris. Synonym: annulus iridis minor. (05 Mar 2000) |
| atresia iridis | Congenital absence of the pupillary opening. Synonym: atretopsia. (05 Mar 2000) |
| vitiligo iridis | Small white patches in brown irides. (05 Mar 2000) |
| circulus arteriosus iridis major | An arterial circle at the ciliary border of the iris. Synonym: circulus arteriosus iridis major. (05 Mar 2000) |
| circulus arteriosus iridis minor | An arterial circle near the pupillary margin of the iris. Synonym: circulus arteriosus iridis minor. (05 Mar 2000) |
| coloboma iridis | Retention of the choroid fissure causing a congenital cleft of the iris, often associated with coloboma of the choroid, viable in the inferior ocular fundus, obsolete term for the iris defect resulting from a large surgical iridectomy. (05 Mar 2000) |
| plicae iridis | Numerous very fine, almost microscopic, radial folds on the posterior surface of the iris that extend around the pupillary margin. Synonym: plicae iridis. (05 Mar 2000) |
| musculus dilator iridis | <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) |
| heterochromia iridis | A difference of colour between the iris of one eye and the other. (a person with one brown and one blue eye has heterochromia iridis.) also, a difference in colour within an iris (sectoral heterochromia iridis). (12 Dec 1998) |
