Vesicular keratitis is associated with infection by pathogenic microorganisms such as Mycobacterium tuberculosis, Staphylococcus aureus, and Chlamydia trachomatis. Vesicular keratitis is a common ophthalmic disease that is caused by microbial proteins that cause an immune response to keratitis. Common causative organisms include Mycobacterium tuberculosis, Staphylococcus aureus, and Chlamydia trachomatis, which can cause the disease if you take care of your eyes. Vesicular keratitis is usually associated with mild pain or a foreign body sensation, tearing, and tenderness, and can be a recurring condition. It is recommended to go to the ophthalmology department of a specialized hospital for treatment of vesicular keratitis, and use suitable medication as prescribed by the doctor. Commonly used medications include flumethasone drops, levofloxacin drops, etc. Surgery, such as corneal transplantation, can be carried out if necessary. If you find vesicular keratitis, please consult the hospital in time to avoid delaying your condition.
