Keratitis is an inflammation or infection of the cornea, the clear front cover of the eye.
Noninfectious keratitis Treatment of noninfectious keratitis varies depending on the cause. However, if your keratitis is caused by a scratch or extended contact lens wear, you may only need a 24-hour eye patch and topical eye medications.
Infectious keratitis Treatment of infectious keratitis varies, depending on the cause of the infection.
- Bacterial keratitis. For mild bacterial keratitis, antibacterial eyedrops may be all you need to effectively treat the infection. If the infection is moderate to severe, you may need to take oral antibiotics to get rid of the infection.
- Fungal keratitis. Keratitis caused by fungi typically requires antifungal eyedrops and oral antifungal medication.
- Viral keratitis. If a virus is causing the infection, antiviral eyedrops and oral antiviral medications may be effective. But these medications may not be able to eliminate the virus completely, and viral keratitis may come back in the future.
- Acanthamoeba keratitis. Keratitis that’s caused by the tiny parasite acanthamoeba can be difficult to treat. Antibiotic eyedrops may be helpful, but some acanthamoeba infections are resistant to medication. Severe cases of acanthamoeba keratitis may require a cornea transplant.
If keratitis doesn’t respond to medication, or if it causes permanent damage to the cornea that significantly impairs your vision, your doctor may recommend a cornea transplant.
