A corneal inflammation due to a herpes virus – either herpes simplex or herpes zoster virus.
Keratitis is an inflammation of the cornea — the clear, dome-shaped tissue on the front of your eye that covers the pupil and iris. Keratitis is sometimes caused by an infection involving bacteria, viruses, fungi or parasites. Non-infectious keratitis can be caused by a minor injury, wearing your contact lenses too long or other noninfectious diseases.
Dr. Boehm talks about the 2 herpes viruses that affect the eye, herpes simplex virus one which causes cold sores and the varicella zoster virus associated with chickenpox and shingles. This is very common and can be treated.
