Reduced Corneal Thickness and Enlarged Anterior Chamber in a Novel ColVIIIa2^G257DMutant Mouse

Abstract

The mouse mutant Aca23 described here offers the first point mutation of the Col8a2 gene in the mouse. The results of this study suggest that a functional collagen VIII alpha2 is essential for the correct assembly of the Descemet's membrane and for corneal stability. Aca23 might be used as a novel model for keratoglobus.
