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 ...

Personalized Corneal Biomechanics [PDF]

, 2019
Degradation or loss of vision greatly influences the quality of life. The shape and optical properties of the cornea are determined by the mechanical balance between intraocular pressure (IOP) and the internal stresses of corneal tissue.
