Ocular microbiota and keratitis

Keratitis is an inflammation of the cornea, the transparent part of the eye that covers the iris and pupil. Keratitis can be caused by several infectious agents, including bacteria, viruses, fungi and protozoa.

The composition of the microbiota of the eye can affect the susceptibility to keratitis and the severity of the pathology.

In some cases, keratitis is caused by the presence of a pathogenic microorganism that colonizes the cornea. In other cases, keratitis can be caused by dysbiosis of the ocular microbiota, which alters the microbial balance and increases the susceptibility of the eye to infection.

Ocular microbiota dysbiosis can be caused by several factors, including antibiotic use, eye surgery, diabetic disease, chemotherapy, and contact lens use. Dysbiosis can lead to a decrease in microbial diversity and an increase in the presence of certain microorganisms, such as the bacteria Staphiloccocus.

Prevention of keratitis depends on the underlying cause of the pathology. However, some strategies that can help maintain a healthy ocular microbiota and prevent dysbiosis include regular cleaning of contact lenses, using antibiotics only when necessary, and protecting the eyes from external infectious agents, such as dust and chemicals.

In addition, the treatment of keratitis depends on the underlying cause of the pathology. However, treatment may include the use of topical, antiviral or antifungal antibiotics, mechanical cleaning of the ocular surface, and pulsed light therapy.
