What eye drops are used for keratitis?

Keratitis is an eye disease caused by infections with bacteria, fungi, viruses, or other microorganisms. Treatment typically involves the use of targeted anti-infective eye drops. The specific type of eye drop used depends on the type of pathogen: 1. Bacterial keratitis: Antibiotic eye drops such as gentamicin, tobramycin, chloramphenicol, or tetracycline derivatives are generally used. In severe cases, oral or intravenous antibiotics may be required. 2. Fungal keratitis: Antifungal medications such as fluconazole, amphotericin B, or natamycin may be required. These medications usually need to be used for a prolonged period and may require combination with oral antifungal agents. 3. Viral keratitis: If caused by herpes simplex virus, antiviral medications such as acyclovir or ganciclovir can be used. For recurrent cases, suppressive therapy may be necessary. 4. Allergic keratitis: Antihistamine or corticosteroid eye drops may be needed to reduce the inflammatory response, such as fluorometholone or dexamethasone. Note: Once symptoms of keratitis appear, such as eye pain, redness, swelling, vision loss, or a foreign body sensation, immediate medical attention should be sought.
