Comparison of In Vitro Corneal Permeation and In Vivo Ocular Bioavailability in Rabbits of Three Marketed Latanoprost Formulations

Background and Objective: All latanoprost formulations currently available for the treatment of glaucoma or ocular hypertension contain the same concentration of latanoprost (0.005%) but differ in excipients, which may affect […]

Ocular side effects of systemic medications: utilization of the 3D human corneal epithelial tissue model

Many systemic medications administered at high doses have the potential to induce unwanted ocular effects, including light sensitivity, pain, or corneal edema that are due to inflammation and/or cytotoxicity. Current […]

Azithromycin and Doxycycline Attenuation of Acanthamoeba Virulence in a Human Corneal Tissue Model

Background: Amoebic keratitis is a potentially blinding eye infection caused by ubiquitous, free-living, environmental acanthamoebae, which are known to harbor bacterial endosymbionts. A Chlamydia-like endosymbiont has previously enhanced Acanthamoeba virulence in vitro.We […]

Molecular Mechanism of Ocular Surface Damage: Dry Eye and Wound Healing Models Using in vitro Reconstructed Human Corneal Tissues

Current methods used to investigate mechanisms of corneal wound healing (CWH) and pathogenesis of dry eye disease (DED) utilize monolayer cell cultures or animals, but there is a need for […]

In Vitro Permeation of Latanoprost Eye Drop Formulations in a 3-Dimensional Normal Human Corneal Tissue Model

Permeation of topically applied ocular drugs occurs predominantly through the cornea and therefore absorption studies using corneal tissues play a critical role in ocular drug formulation. The purpose of the […]
