The Slate turkey: a model for secondary angle closure glaucoma.
An inherited eye disease leading to a secondary angle closure glaucoma has been observed in turkeys (Meleagris gallapavo) of the Slate variety. The initial indications of the disease involve a low grade aqueous cell and flare reaction, associated with progressive posterior synechiae formation resulting in pupillary block and iris bombé. A midperipheral iridocorneal adhesion follows, accompanied by corneal edema, breaks in Descemet's membrane, and buphthalmos. IOP is not elevated substantially until a complete iris bombé occurs. Expression of the defect is sex-influenced, with females exhibiting the most severe pathological changes.
