Keratitis

What is Keratitis?

Keratitis is a condition characterised by the inflammation of the cornea. The condition is marked by the presence of a clear dome on the front surface of the eye, which becomes inflamed. Nearly 1 million people are diagnosed with keratitis annually.

Risk Factors

Several risk factors are considered to be the cause of keratitis which may include-

• Contact lens wearers
• Known history of cold sores, chicken pox or shingles
• Frequent eye drops users
• Dry eyes
• Corneal injury or burns
• Bell's palsy and other eyelid disorders that prevent proper eyelid function

Infection is the most frequent cause of keratitis. Bacteria, viruses, fungi and parasitic organisms may infect cornea leading to infectious or microbial keratitis.

Signs and Symptoms

The most common symptoms of keratitis are pain, redness, and blurring of vision with tearing of eyes. The pain may be mild to severe, depending on the cause of the inflammation. Sensitivity to light may also be present. The cornea might appear white or grey in colour.

To diagnose keratitis, the ophthalmologist will consider the history of the symptoms followed by a corneal examination. Also, the corneal or tear sample may be collected to identify the exact cause of keratitis.

Management

Superficial keratitis does not lead to scarring. However, extensive keratitis can affect deeper layers of cornea which may cause the formation of corneal ulcer and scar. Keratitis, if untreated, may lead to permanent loss of vision. Make sure to wash your hands properly before touching your eyes to prevent any kind of infection. Replace your contact lenses regularly and handle them with clean hands. Prescription medicines are required for the proper treatment of keratitis after being diagnosed by an eye specialist only.
