What Causes Keratitis?
Keratitis refers to inflammations, infections or deterioration of the corneas. It has numerous causes. No matter what the cause, early treatment is essential to preserve sight and prevent permanent or further damage to the corneas. Viruses cause some forms of keratitis. Some viruses indicated in keratitis are Herpes Simplex 1 and 2, rubella, measles, and mumps. Though very rare, mononucleosis may also cause keratitis. Certain bacteria may also be responsible for producing keratitis. Exposure to either staphylococcus and streptococcus when left untreated, can cause significant damage to the eyes. If one suspects eye infections, a doctor will usually prescribe drop antibiotics to prevent bacteria from attacking the corneal tissue. Sometimes, keratitis develops as a reaction to certain antibiotics, or when antibiotics cause harmful fungi to develop. Treatment for fungal infections generally involves oral doses of anti-fungal medications. Fungal infections are common in those with immunosu
Eye infection: Keratitis caused by an eye infection usually happens after eye trauma or surgery. An eye infection may be due to any of the following: Bacteria: Different bacteria (germs), such as those that cause tuberculosis, leprosy, and syphilis, may cause keratitis. Newborn babies may get infected with bacteria as they pass through the mother’s birth canal.Fungus: In some cases, keratitis may be caused by a fungus (yeast-like germs). These are organisms which usually cause problems when the immune system becomes weak. The immune system is the part of your body that fights infection.Parasite: Infection by a parasite (bug) usually occurs with poor hygiene, such as in poor contact lens care. You may also get the parasite by using contaminated (dirty) water or contaminated eye drops.Viruses: Viruses that cause cold sores or chicken pox may also cause keratitis. Other diseases: Keratitis may happen as a result of diseases causing inflammation. These may include autoimmune diseases, such
The most frequent causes of keratitis include dry eye resulting from an eyelid disorder or insufficient tear formation, Vitamin A deficiency, foreign object in the eye, intense light (such as welding), allergies, and misuse or overuse of contact lenses. Viral, bacterial, and fungal infections are also causes of keratitis. The most common infection is the herpes simplex virus infection. Herpes simplex keratitis occurs as a result of the herpes simplex infection. It commonly leads to recurring inflammation of the cornea, scarring, and loss of vision. Anyone suspecting herpes simplex keratitis should seek immediate medical attention for prompt treatment. In severe, rare cases where the cornea is damaged, an eye care professional may recommend surgery. If left untreated, keratitis can cause ulcers on the cornea, glaucoma, permanent scarring of the eye, and permanent loss of vision. The biggest risk factors for developing keratitis include poor nutrition, crowded or unsanitary living condit
