Morphology of the cataract in albino mutant quails (Coturnix coturnix japonica). 1985

K Takatsuji, and S Iizuka, and H Nakatani, and A Nakamura

Morphological changes in cataractous albino quail lens were studied by light microscopy. In some animals, a pin-head opacity in the lens could first be detected with the naked eye 2 months after hatching. Faint anterior or posterior cortical opacity was observed in many lenses at 3 months of age. Most lenses had turned opaque 12 months after hatching. Lens dimensions were markedly enlarged at 6 months of age. Vacuoles were present in the posterior surface just beneath the capsule and equatorial epithelium, before the cells became degenerative. Many swollen lens fibers and abnormally migrated cells were observed in the posterior cortical region. The lens was covered with several layers of epithelioid cells in the mature cataract.

UI	MeSH Term	Description	Entries
D007908	Lens, Crystalline	A transparent, biconvex structure of the EYE, enclosed in a capsule and situated behind the IRIS and in front of the vitreous humor (VITREOUS BODY). It is slightly overlapped at its margin by the ciliary processes. Adaptation by the CILIARY BODY is crucial for OCULAR ACCOMMODATION.	Eye Lens,Lens, Eye,Crystalline Lens
D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations
D011784	Quail	Common name for two distinct groups of BIRDS in the order GALLIFORMES: the New World or American quails of the family Odontophoridae and the Old World quails in the genus COTURNIX, family Phasianidae.	Quails
D002386	Cataract	Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence).

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
