Corneal infection also know as “corneal ulcer” and can broadly be divided into infective and non-infective.
In corneal infections eye becomes very painful, red, sensitive to light and may be associated with drop in vision.
Infective keratitis can be caused by a number of pathogens, the most common being bacteria, fungi, virus. They require a detailed examination, microbiological work-up to isolate the causative pathogen and accordingly target treatment for the same. Such cases require frequent follow-ups, frequent administration of drugs (drops or injections) to prevent the infection from spreading into deeper layers and penetrating other structures of the eye.
A therapeutic keratoplasty is a surgery in which the infected cornea is replaced with a healthy one when the infection is very severe and not responding to topical treatment or to reduce the load of infective pathogens in the eye when the infection has involved a large area of the cornea.
Non infective keratitis may require a systemic evaluation to rule out an underlying causative factor. They may require systemic immunosuppressant based on the underlying etiology.
