Corneal ulcer is an open sore on the cornea, most cases of which are caused by infections. There are mainly three types of causes for corneal ulcer. 1. Bacterial infection, which is very common for people wearing contact lenses. 2. Viral infection, includes herpex simplex virus and varicellar virus. 3. Fungal infection together with over-use of contact lenses and eye drops with steroids might cause this condition too. Injuries or trauma to eyes could make it easier to get corneal ulcer. What are symptoms of corneal ulcer? With corneal ulcer, you might develop redness, pain, foreign body sensation, tearing, pus or thick discharge, blurry vision, swollen eyelids and a white or grey spot on the cornea is visible. Once you feel severe pain in eyes, or obvious discharge from eyes, or any serious symptoms stated earlier you got, it is time to see a doctor. You could adapt some home care actions to help. Don’t wear contact lense until you are completely healed. Apply cool compress on the infected eye to help relieve. Don't touch or rub your eyes, especially with hands which are not completely cleansed.
