is a more prevalent cause of corneal ulcers in developing countries than in developed countries. We report five cases of corneal ulcers attributed to this organism with a literature review on bacterial cornea ulcers. Among the patients, four had underlying systemic illnesses while one was otherwise healthy. Four patients were presented with visual acuity worse than 6/60, and one patient had a visual acuity of 6/18. Two of the patients developed corneal perforation, which required tectonic penetrating keratoplasty. For visual outcome, two patients improved to visual acuities of 6/24 and 6/12, while three others had hand movement (HM) vision. All patients received broad-spectrum antibiotics, which were later adjusted based on culture sensitivity results. Notably, keratitis lacks specific ulcerative characteristics and can progress rapidly, frequently resulting in a guarded visual prognosis.
在发展中国家，它是导致角膜溃疡的一个比发达国家更为普遍的原因。我们报告了5例归因于该微生物的角膜溃疡病例，并对细菌性角膜溃疡进行了文献综述。在这些患者中，4例有潜在的全身性疾病，1例则健康状况良好。4例患者的视力低于6/60，1例患者的视力为6/18。2例患者发生了角膜穿孔，这需要进行结构性穿透性角膜移植术。在视力转归方面，2例患者的视力提高到6/24和6/12，而另外3例患者只有手动视力。所有患者均接受了广谱抗生素治疗，随后根据培养敏感性结果进行了调整。值得注意的是，角膜炎缺乏特异性溃疡特征，且进展迅速，常常导致视力预后不佳。
