Keratitis refers to the inflammation of one’s cornea, which is the outermost part of the eye that covers the iris and the pupil. Two of the most common causes of keratitis include injury and infection. Several bacterial, parasitic, viral and fungal infections can lead to kerasitis. If the kerasitis is infectious it can develop post injury to the cornea, though this injury can easily inflame the cornea without a secondary infection.
Keratitis that is caused by virus or bacterium usually tends to get better quickly. Herpes keratitis as well as bacterial keratitis can be easily treated with antiviral medication or antibiotics. Keratitis that is caused by other viruses tends to get better on its own within few days. If the keratitis is related to only the contact lenses, then the duration of the recovery period will be brief.
Keratitis that is caused by an autoimmune disease, parasites or a prior injury can become difficult to treat and may also be long lasting. In such cases, one may experience permanent damage to the cornea that is accompanied by impaired vision; this may occur despite an intense treatment program.
