Subepithelial infiltrates (SEI). SEIs generally occur after viral keratitis, but are also found in blepharitis and contact lens-related hypersensitivity. White blood cells from the limbal vasculature are drawn into the avascular cornea.
What is Inflammation?
Inflammation is the body’s response to protect tissues and organs. It is an efficient response caused by injury, infection, autoimmune processes or idiopathic conditions. During this process, the body’s white blood cells and other immune factors protect against foreign pathogens such as bacteria and viruses. In certain conditions, there are symptoms such as redness, warmth, swelling and pain. Inflammation is best treated with a short course of steroids.
