Blood tests to check for inflammatory disorders may also be needed.
Treatment for corneal ulcers and infections depends on the cause. Treatment should be started as soon as possible to prevent scarring of the cornea.
If the exact cause is not known, patients may be given antibiotic drops that work against many kinds of bacteria.
Once the exact cause is known, drops that treat bacteria, herpes, other viruses, or a fungus are prescribed. Severe ulcers sometimes require a corneal transplant.
Corticosteroid eye drops may be used to reduce swelling and inflammation in certain conditions.
Your health care provider may also recommend that you:
Avoid eye makeup
Don't wear contact lenses at all, or don't wear them at night
Take pain medications
Wear an eye patch to keep out light and help with symptoms
Wear protective glasses
Many people recover completely from corneal ulcers or infections, or they have only a minor change in vision.
However, a corneal ulcer or infection can cause long-term damage to the cornea and affect vision.
Untreated corneal ulcers and infections may lead to:
Loss of the eye (rare)
Severe vision loss
Scars on the cornea
Calling your health care provider
Call your health care provider if:
You have symptoms of corneal ulcers or an infection
You have been diagnosed with this condition and your symptoms become worse after treatment
Getting treated for an eye infection by an ophthalmologist right away may prevent ulcers from forming. Wash hands and pay very close attention to cleanliness while handling contact lenses. Avoid wearing contact lenses overnight.
