Effects of Aberrant Pax6 Gene Dosage on Mouse Corneal Pathophysiology and Corneal Epithelial Homeostasis [PDF]

, 2011
Background: Altered dosage of the transcription factor PAX6 causes multiple human eye pathophysiologies. PAX6(+/-) heterozygotes suffer from aniridia and aniridia-related keratopathy (ARK), a corneal deterioration that probably involves a limbal ...

Corneal topography by keratometry [PDF]

British Journal of Ophthalmology, 2000
To investigate the ability of a telecentric keratometer to describe the asphericity and curvature of convex ellipsoidal surfaces and human corneas.22 conicoidal convex surfaces and 30 human corneas were examined by conventional keratometry. Additional keratometric measurements were made when the surface was tilted in the horizontal plane relative to ...
