Analyzed were the ascorbate, fibronectin, hyaluronic acid, metalloproteinase inhibitors, EGF, FGF, NGF, insulin, and IGF-1 (corneal ulcer healing), the antiangiogenic agents (endostatin, PAI-1, PEDF, angiostatin, TSP-1, TSP-2, IFN-α), corticosteroids, NSAIDs, cyclosporine A, anti-VEGF drops (treatment of corneal neovascularization), and alpha 2-agonists, beta-blockers, carboanhydrase inhibitors, muscarinic agonists, Rho-kinase inhibitors, and prostaglandin analogs (glaucoma). Here, INS is linked to corneal ulcer.
