Acinetobacter group has been known as gram-negative, opportunistic, aerobic coccobacilli which exists on skin, mucus membranes and in the urinary tract with relatively low virulence. Some predisposing factors including underlying systemic diseases, using broad spectrum antibiotic, mechanical ventilation and etc. could pose the more sever involvement with Acinetobacter. In this study, we reported a patient with Acinetobacter corneal ulcer and a relatively comprehensive review literature about this rarely ocular involvement with this bacteria.
