| anterior chamber | The space in the eye, filled with aqueous humor, bounded anteriorly by the cornea and a small portion of the sclera and posteriorly by a small portion of the ciliary body, the iris, and that part of the crystalline lens which presents through the pupil. (12 Dec 1998) |
| anterior chamber cleavage syndrome | <syndrome> A congenital disorder originating from faulty separation of embryonic structures; it results in bilateral central corneal opacities, with an anterior ring attachment of the iridic pupillary border and anterior polar cataracts; associated with short-limbed dwarfism; autosomal dominant inheritance. See: iridocorneal endothelial syndrome. Synonym: Peters' anomaly. (05 Mar 2000) |
| anterior chamber of eye | The space between the cornea anteriorly and the iris/pupil posteriorly, filled with a watery fluid (aqueous humor) and communicating through the pupil with the posterior chamber. Synonym: camera anterior bulbi, camera oculi anterior, camera oculi major. (05 Mar 2000) |

| Boyden chamber | <apparatus> Simple chamber used to test for chemotaxis, especially of leucocytes. Consists of two compartments separated by a millipore filter (3-8 m pore size), chemotactic factor is placed in one compartment and the gradient develops across the thickness of the filter (ca 150 m). Cell movement into the filter is measured after an incubation period less than the time taken for the gradient to decay. See: checkerboard assay. (18 Nov 1997) |

| Sandison-Clark chamber | A chamber that can be fitted over a hole punched in a rabbit's ear, so that tissue will grow to fill the defect between two transparent plates; if the distance between the plates is small, the living tissue can be studied microscopically. (05 Mar 2000) |
