The mechanisms ministration (eitherpreclinical evidence supporting the useful effects of vitamin A of administration (either systemically or topically) around the ocular surface. The mechanisms of action of vitamin A around the OS are reported in Figure 1. Vitamin A increases conjunctival action of vitamin A around the OS are reported in Figure 1. Vitamin A increases conjunctival mucin expression and promotes right corneal and conjunctival wound healing, reducmucin expression and promotes correct corneal and conjunctival wound healing, decreasing ing keratinization. These effects happen to be shown by quite a few studies distinct animalaniusing unique keratinization. These effects happen to be shown by many studies applying mal models of DED: vitamin A promotes wound healing [4] by improving epithelialepimodels of DED: vitamin A promotes wound healing [4] by directly directly enhancing thelial [5,6], and reducingreducing cell apoptosis [7] and corneal CDK19 Formulation keratinization [8].are repair repair [5,6], and cell apoptosis [7] and corneal keratinization [8].
