What causes keratitis?
How is keratitis treated?
Keratitis is an infection or inflammation of the cornea, the transparent front covering of the eye that covers the iris and pupil (See Anatomy of the Eye). Depending on the cause and with early treatment, most cases are curable.
The symptoms of keratitis may include eye pain, light sensitivity, the feeling that something irritating is in the eye, excessive tearing and blurred vision. A minor decrease in visual acuity may also occur.
The most frequent causes of keratitis include dry eye resulting from an eyelid disorder or insufficient tear formation, Vitamin A deficiency, foreign object in the eye, intense light (such as welding), allergies, and misuse or overuse of contact lenses. Viral, bacterial, and fungal infections are also causes of keratitis. The most common infection is the herpes simplex virus infection.
Herpes simplex keratitis occurs as a result of the herpes simplex infection. It commonly leads to recurring inflammation of the cornea, scarring, and loss of vision. Anyone suspecting herpes simplex keratitis should seek immediate medical attention for prompt treatment. In severe, rare cases where the cornea is damaged, an eye care professional may recommend surgery. If left untreated, keratitis can cause ulcers on the cornea, glaucoma, permanent scarring of the eye, and permanent loss of vision.
The biggest risk factors for developing keratitis include poor nutrition, crowded or unsanitary living conditions, lowered resistance as a result of another illness, wearing contact lenses, or the presence of viral infections elsewhere in the body such as cold sores or genital herpes.
To prevent keratitis from recurring, wear glasses if work involves eye hazards. Visit their physician if you suspect any viral, bacterial, or fungal infection. In addition, modify your diet to ensure adequate Vitamin A.
After it is diagnosed, keratitis can be treated with eye medications such as antibiotics or antiviral eye drops and ointments. Nonprescription eye drops containing topical corticosteroids should not be used. Eye patches aid in the protection and healing of the infected eye. The doctor may also recommend discontinued use of contact lenses until the infection clears.
