keratoconjunctivitisszel

Keratoconjunctivitis is a medical term that describes inflammation of both the cornea and the conjunctiva. The cornea is the transparent outer layer at the front of the eye that covers the iris and pupil, while the conjunctiva is the thin, transparent membrane that lines the sclera (the white part of the eye) and the inner surface of the eyelids. When both of these tissues become inflamed, it is referred to as keratoconjunctivitis.

This condition can be caused by a variety of factors, including viral infections, bacterial infections, allergies, and irritants. Viral keratoconjunctivitis is often highly contagious and can be caused by the same viruses that cause the common cold. Bacterial keratoconjunctivitis can develop from an infection that spreads to the eye, or from contact lens contamination. Allergic keratoconjunctivitis is a response to allergens such as pollen, dust mites, or pet dander. Irritant causes can include exposure to smoke, chemicals, or dry air.

Symptoms of keratoconjunctivitis can include redness of the eyes, watering, a gritty or sandy sensation, itching, sensitivity to light, and blurred vision. In some cases, discharge may be present, which can be watery, mucousy, or purulent depending on the cause. Diagnosis is typically made through a clinical examination by an eye care professional, and sometimes laboratory tests may be performed to identify the underlying cause. Treatment varies depending on the etiology and may involve antiviral medications, antibiotic eye drops, antihistamines, or lubricating eye drops. Preventing the spread of infectious forms involves good hygiene practices, such as frequent hand washing and avoiding touching the eyes.
