Keratitis is an acute or chronic inflammatory disorder of the cornea, the clear anterior segment of the eye Pathophysiologically, this inflammation causes corneal opacification, epithelial breakdown, and potentially stromal ulceration, clinically presenting with eye pain, redness, photophobia, tearing, and variable degrees of visual impairment

The condition can arise in any population, with major predisposing factors including contact lens wear, ocular trauma, ocular surface disease, or systemic autoimmune disorders It is characterized by inflammatory cell infiltration of the corneal epithelium and stroma in response to infectious pathogens—such as bacteria, viruses, fungi, or parasites—or noninfectious mechanical, chemical, and immune-mediated insults Pathophysiologically, this inflammation causes corneal opacification, epithelial br...
