Keratitis is an inflammation in the cornea, caused by a bacterial infection in it, generally said infection is caused by the use of contact lenses or a direct injury to the eye, it is characterized by causing quite intense pain in the affected area, in addition to sensitivity to light rays, tear secretion and decreased vision, the bacteria responsible for causing the infection is Staphylococcus Aureus.
This infection can be divided into two types, deep and superficial keratitis, the latter causing infection in the epithelial tissue of the cornea and in turn is subdivided into filamentous keratitis, so named since small filaments are attached to a part of the surface of the cornea, causing the sensation of having a foreign body in the eye. in secondplace is punctate keratitis, which is the most common of all, characterized by presenting lesions in different areas of the cornea. The last of the superficial keratitis is ulcerative, the main characteristic of which is the formation of an ulcer on the surface of the cornea. Finally, they have deep keratitis that can reach higher levels of infection due to the infection penetrating other tissues.
To identify keratitis, the symptoms with which it is characterized must be known, among the main ones we can mention the sudden and strong pain in the eye, spontaneous and constant tear secretions, ultra sensitivity to light rays and it is greatly reduced As far as vision is concerned, the most recommended in case of presenting symptoms is to go to the ophthalmologist, since if this infection is not treated in time it can cause total loss of vision.
The main causes that usually generate keratitis are direct injuries to the eye, which may be an object that has penetrated the surface of the cornea, facilitating access for bacteria in the eye, the use of contact lenses that are contaminated by bacteria, parasites or fungi that live on the surface of the lens and that when they come into contact with the eye cause infection, viruses such as those that cause herpes and chlamydia can also be factors that cause keratitis.
