Also, a corneal injury that results in plant material getting into the eye can lead to fungal keratitis.  Acanthamoeba are microscopic, single-celled amoeba that can cause human infection.

An ulcer, regardless of the cause, can cause abdominal pain, bleeding, or even cause a hole (perforation). An ulcer is maintained by an acid environment in the stomach and pepsin, which is produced in the stomach. Chronic infection with H. pylori causes an increase in acid.

Eye Herpes (Ocular Herpes) Caused by the type 1 herpes simplex virus, eye herpes (ocular herpes) is a common, recurrent viral infection affecting the eyes. This type of herpes virus can cause inflammation and scarring of the cornea that sometimes is referred to as a cold sore on the eye.Herpes of the eye can be transmitted through close contact with an infected person whose virus is active. Herpes keratitis is the most common form of eye herpes and is a viral corneal infection. 2  Ocular herpes in this form generally affects only the top layer, or the epithelium, of the cornea, and usually heals without scarring. 3  Stromal keratitis occurs when the infection goes deeper into the layers of the cornea.

This is the same bacteria that causes strep throat and many other infectious problems in our body.
