Keratitis (also known as corneal ulcer) is the medical term for inflammation of the cornea, a dome-shaped window present in the front of the eye (the black central part of the eye). Dr Devesh Sharma, Consultant, Cornea & Anterior segment, Amritsar Eye Clinic, Dehradun says, ‘There are innumerable factors that can lead to keratitis, but the commonest ones are due to an infection. Apart from this, direct injuries to the eye caused due to mud or dirt particles, sticks and bamboo also lead to this disease. However, using adequate protection, like wearing goggles or protective gear, one can reduce the risk of mechanical injuries to the eye and thus, related infection of the eyes.’
Patients with keratitis normally complain of severe pain, redness and watering from the eyes and poor vision. Some may report a whitish or yellowish discolouration of the cornea. ‘For diagnosis, eye specialists may take small samples from the eye for assessment in a laboratory to find out the microbes causing the infection. Over the past few years, newer drugs have come up for managing and successfully treating even the most resistant of infections,’ says Dr Devesh Sharma. Here is detailed information on corneal ulcer – causes, symptoms, diagnosis, treatment and prevention.
