What causes ulcers in the eyes?

The term ulcer is most commonly used to refer to a corneal ulcer.  The most common cause of corneal ulcer is bacterial infection from contact lens use.  One may also get bacterial infections from eyelid bacteria seen in blepharitis.  Viruses such as herpes simplex and varicella zoster can cause corneal ulcers.  Severe dry eyes can cause ulcers as well.  Exposure of the eye in the case of poor functioning of eyelids also predisposes to an ulcer.  Corneal ulcers can also be due to inflammation without infection and they can also be a form of degeneration in the cornea that is either age or inheritance. Any type of ulcer of the cornea is a medical emergency that must be attended to by an Eye M.D. as soon as possible.
