Acinetobacter species are common aerobic gram-negative bacterium that contain polymorphisms. Acinetobacter baumannii keratitis has recently received attention, and has various clinical features. Therefore, it is crucial to determine the appropriate medical treatment for Acinetobacter baumannii keratitis.

There were two infectious crystalline keratitis patients, two other patients that were co-infected with fungus, and the last patient who had the peripheral corneal ulcer type of keratitis.

Acinetobacter baumannii keratitis demonstrates multiple clinical features. It forms a biofilm that can bring possible resistance to therapy, and it can also co-infect with fungus. In contrast to general bacterial keratitis which occurs in the form of a central corneal ulcer, we found Acinetobacter baumannii to take on the form of a peripheral corneal ulcer in our experiments on the five keratitis patients. Although Acinetobacter species were originally found to be multidrug-resistant, such resistance was not found in our experiments. However, due to the various problems associated with Acinetobacter baumannii, it is always critical for medical staff to take infection of Acinetobacter baumannii into consideration in keratitis patients.
