As an eye specialist, we frequently come across cases of eye injuries which if were taken seriously in the earlier stages would have never progressed to forming a corneal ulcer. This article discusses all one needs to know about corneal ulcer.
What is Corneal Ulcer?
Corneal Ulcer also known as Ulcerative Keratitis is an inflammatory condition of the cornea (clear tissue in front of the eye) involving disturbance of its epithelial layer with the involvement of the corneal stroma. It presents as redness in the eye, pain in the eye, mild to severe eye discharge and reduced vision.
Causes of Corneal Ulcer:
Most of the corneal Ulcer is caused by fungi, viruses, bacteria and protozoa.
A) Infectious cause:
Canthamoeba keratitis: It is a rare eye disease in which amoeba invade the cornea of the eye, resulting in visual impairment or blindness. This infection occurs in people who frequently wear contact lenses. To prevent the condition, the contact lens must be properly disinfected before wearing.
Herpes Simplex Keratitis: Herpes Simplex Keratitis is a viral infection of the eye caused by Herpes simplex virus. It is a viral infection that causes repeated flare ups which involve lesions or sores in the eye and if not treated leads to an ulcer in the eye. Therefore, make sure to complete the treatment of Herpes Simplex.
B) Eye Injury: Injury to the eye resulting in abrasions or scratch to the cornea, if left untreated, leads to ulcer formation. Scratches, scrapes and cuts from fingernails, paper cuts, makeup brushes etc. can become infected by bacteria and lead to corneal ulcers.
C) Dry Eye Syndrome: Dry eyes develop when the eye is unable to maintain a healthy coating of the eye with the help of tears. In such cases, the eye is too dry to protect itself and this becomes a good base for the bacteria and fungi. Therefore, get an eye specialist’s opinion who would prescribe eye drops that help in lubricating the eyes and keeping them moist. This would prevent the ulcer formation.
D) Vitamin A deficiency: People who have a dietary deficiency of Vitamin A are at risk of developing Corneal Ulcer.
