anterior chamber cleavage syndrome

an·te·ri·or cham·ber cleav·age syn·drome

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; these are autosomal dominant and autosomal recessive forms, caused by mutation in the PAX6 gene, the PITX2 gene, the CYP1B1, or the FOXC1 gene. See: iridocorneal endothelial syndrome.
Synonym(s): Peters anomaly

Peter's anomaly

A rare, congenital anomaly of the anterior segment of the eye. It is characterized by a central corneal opacity, usually accompanied by the adhesion of strands of iris tissue to the margins of the opacity, thinning of the stroma and attenuation or absence of Descemet's membrane. A variant of Peter's anomaly (called type 2) presents in addition to the above, either a displacement or a lack of transparency of the lens, which may even become adherent to the posterior surface of the cornea. It is frequently associated with glaucoma. Syn. anterior chamber cleavage syndrome. See Axenfeld's syndrome; Rieger's syndrome.
