Keratitis is the inflammation of the cornea, the eye’s clear dome surface. Its symptoms include eye redness and pain, impaired vision, light sensitivity, and having a gritty sensation. The infection may be due to bacteria, fungi, amoeba, or parasites. Keratitis may also be caused by the inadequate closure of the eyes which leads to corneal dryness. Moreover, the inflammation may be due to intense ultraviolet radiation exposure. The treatment generally involves eliminating the pathogen.
