Topical rosiglitazone is an effective anti-scarring agent in the cornea [PDF]

, 2013
Corneal scarring remains a major cause of blindness world-wide, with limited treatment options, all of which have side-effects. Here, we tested the hypothesis that topical application of Rosiglitazone, a Thiazolidinedione and ligand of peroxisome ...

On the Relationship between Corneal Biomechanics, Macrostructure, and Optical Properties

Journal of Imaging, 2021
Optical properties of the cornea are responsible for correct vision; the ultrastructure allows optical transparency, and the biomechanical properties govern the shape, elasticity, or stiffness of the cornea, affecting ocular integrity and intraocular ...
