The cornea is made up of 6 layers of highly specialized skin cells. The corneal epithelium is the outermost layer, followed by the Bowman’s layer, the corneal stroma, Descemet’s membrane, the corneal endothelium and the Dua’s layer.
A corneal abrasion occurs upon erosion of a few of the layers of the epithelium. When a deeper erosion through the entire epithelium and into the stroma is detected, the result is a corneal ulcer. Corneal ulcers are most commonly caused by a blunt trauma or a chemical burn of the cornea.
I-MED Animal Health offers VET SHIELDTM which is ideal for the protection of ocular surfaces following corneal surgery, trauma, abrasions or ulcers. It forms a permeable, non-refractive protective barrier on the surface of the cornea for a period of at least 3 days. The VET SHIELDTM allows water-based medications to pass through and reach the traumatized cornea, but it is not permeable to ointments and oil-based solutions.
