'''Keratoconjunctivitis''' is [[inflammation]] ("-itis") of the [[cornea]] and [[conjunctiva]].

When only the [[cornea]] is inflamed, it is called ''[[keratitis]]''; when only the [[conjunctiva]] is inflamed, it is called ''[[conjunctivitis]]''.

There are several potential causes of the inflammation:
* [[Keratoconjunctivitis sicca]] is used when the inflammation is due to dryness. ("Sicca" means "dryness" in medical contexts.) 
* The term "[[Vernal keratoconjunctivitis]]" (VKC) is used to refer to keratoconjunctivitis occurring in [[Spring (season)|spring]], and is usually considered to be due to [[allergen]]s.
* "Atopic keratoconjunctivitis" is one manifestation of [[atopy]].
* "Epidemic keratoconjunctivitis" is caused by an [[adenovirus]] infection.
* "[[Infectious bovine keratoconjunctivitis]]" (IBK) is a disease affecting cattle caused by the bacteria [[Moraxella bovis]].
* "[[Superior limbic keratoconjuctivitis]]" is thought to be caused by mechanical trauma.
* "Keratoconjunctivitis photoelectrica" ([[arc eye]]) means inflammation caused by photoelectric UV light. It is a type of [[ultraviolet keratitis]]. Such UV exposure can be caused by arc [[welding]] without wearing protective eye glass, or by high altitude exposure from sunlight reflected from snow ("[[snow blindness]]"). The inflammation will only appear after about 6 to 12 hours. It can be treated by rest, as the inflammation usually heals after 24-48 hours.  Proper eye protection should be worn to prevent keratoconjunctivitis photoelectrica.
