                      General Information



Keratitis is inflammation (with or without infection) of the

clear front layer of the eyeball (cornea).  It may be a serious

threat to vision.



The cornea has 4 distinct layers and is less than a millimeter

thick.  Normally it contains no blood vessels or pigment and is

transparent.  Disease or injury may cause cloudiness,

pigmentation, vessel ingrowth and ulcerations.



Causes of keratitis include injuries, irritation, immune or

allergic reactions, infection and birth defects.



Keratitis is described according to the corneal layers affected

and the shape and nature of the abnormality.  Some types include

superficial, interstitial, deep, ulcerative, pigmentary,

punctate, dystrophic, allergic and degenerative keratitis.



                 Important Points in Treatment



1.  Treatment varies according to the type and severity of the

    keratitis.



2.  Laboratory tests and surgery may be required.



3.  It is important to prevent further irritation to the eye(s)

    from contaminated water, wind, sand, sprays, smoke and

    trauma.
