Amongst the known bacterial infections causing harm to the cornea, Bacterial Keratitis is one of them. Under the influence of this disorder, one can feel a lot of pain, sensitivity towards light, diminished and unclear vision and thus can observe tearing or displacement from the eyes. All this is a result of the infection caused by the use of contact lenses. It can also be caused due to an eye injury. It is inferred that Bacterial Keratitis grows within no time. It requires immediate medical attention and treatment or else can lead to blindness.
Within the scope of this disorder there are two major bifurcations known as superficial Keratitis and deep Keratitis. The superficial Keratitis impacts the uppermost layer of the cornea whereas deep Keratitis goes inside the cornea and impacts its internal layers. In the former case, there is no scar left after the treatment but in the latter case a scar is left back which may or may not affect the vision.
There are several causes associated with the occurring of Bacterial Keratitis. One of the major causes of this disorder is extensive usage of the contact lenses. Extended hours of wearing them can create bacterial reaction and thus cause this disorder to occur. Impure eye medication or improper solution applied in the eyes can also be a cause of this disorder. Sometimes, usage of topical steroids can also cause this disease to occur. Other responsible causes for such disorder are diminished immunity due to alcohol addiction, diabetes, improper nutrition or a corneal disease which may have occurred in the recent past.
Signs & Symptoms
There are various signs indicating the occurrence of Bacterial Keratitis such as conjunctival infection as well as focal white impurities. Stromal edemas, shrinking of the cornea, mucopurulent discharge, endothelial inflammatory plaque, etc are some of the scientific sings indicating the occurrence of this disorder.
The most common symptoms of Bacterial Keratitis are painful sensation and vision blurring. The pain can be crucial or mild based on the reason causing the inflammation. Sensitivity toward light is yet another symptom of detecting this disorder. Most often, the eyes of the affected person appear watery as well as red and the corneal part may appear grey or whitish.
An ophthalmologist is the one who can diagnose this disorder. The diagnosis is carried out by asking a series of medical related questions. The medical examiner will thoroughly check all regions of the eyes and will specifically examine the cornea by using a slit lamp. A special dye is used as an eyedrop to conduct such an eye examination.
The treatment prescribed for Bacterial Keratitis mostly depends on type of infection and the level at which it has reached. Most infections are treated by making use of anti bacterial or anti fungal medication or therapy. Any type of foreign body found in the corneal region needs to be eradicated immediately. Steroid drops are mostly prescribed for reducing the inflammatory effect caused in the eye.
Basic hygiene along with some extra care can help you prevent such disorders. One of the most important aspects is changing of lenses daily. It is also important to properly wash your hands when before touching the contact lenses. Making use of sterilized items for handling contact lenses can be of great use.
