Globally, infectious keratitis is the fifth leading cause of blindness. The main predisposing factors include contact lens wear, ocular injury and ocular surface disease. Staphylococcus species, Pseudomonas aeruginosa, Fusarium species, Candida species and Acanthamoeba species are the most common causal organisms.

Bacterial keratitis is a serious bacterial infection of the cornea which can, in severe cases, cause loss of vision. Although infectious ulcers may also be due to fungi, viruses, mycobacteria and protozoa, bacteria are the most common cause of infectious keratitis. Both gram positive and gram negative organisms are implicated as causative agents.

Among all aetiologies such as infection, trauma, inflammation, degeneration and nutritional deficiency, infectious keratitis (IK) represents the leading cause of corneal blindness in both developed and developing countries, with an estimated incidence ranging from 2.5 to 799 per 100,000 population-year.

2024年7月2日 · Keratitis is an inflammation of the cornea — the clear, dome-shaped tissue on the front of your eye that covers the pupil and iris. Keratitis may or may not be associated with an infection. Noninfectious keratitis can be caused by a relatively minor injury, such as from wearing your contact lenses too long or getting a foreign body in the eye.

2022年10月8日 · Keratitis: sight-threatening infection and inflammation of the cornea. Causes: bacterial (Staphylococcus, Streptococcus, Pseudomonas), viral (HSV, VZV), fungal (Fusarium, Aspergillus, Candida), protozoan (Acanthamoeba). Risk factors: contact lens wear, corneal trauma, ocular surface disease, immunosuppression.

Keratitis can be divided into two categories based on cause: infectious keratitis or noninfectious keratitis. Some people call infectious keratitis “microbial” keratitis. Early signs and symptoms of keratitis include eye pain and redness .

2023年8月25日 · Keratitis is the inflammation of the cornea and is characterized by corneal edema, infiltration of inflammatory cells, and ciliary congestion. It is associated with both infectious and noninfectious diseases, which may be systemic or localized to the ocular surface.
