Abstract：
BACKGROUND: Corneal opacity can be caused by various disease. Generally, the opacity gradually increases as the disease progresses. Sudden corneal opacity is mainly caused by corneal trauma, toxic drugs entering the cornea, or acute edema of the keratoconus. However, sudden corneal opacity caused by diabetes has not been reported.
METHODS: A 60-year-old man reported blurred vision and the black eye became white in appearance in the left eye for 5 days. The patient had a history of diabetes which had not been treated.
METHODS: He underwent slit-lamp examination, anterior segment optical coherence tomography, ultrasound bio microscopy, B-mode ultrasound, corneal endothelial examination, random blood glucose testing, and other examinations. The diagnosis of Diabetic Keratopathy was made.
METHODS: Topical glucocorticoids and dilating eye drops were administered and undergo blood sugar control treatment.
RESULTS: The corneal of the patient was completely transparent in a few days, and the flocculent exudation in the anterior chamber disappeared.
CONCLUSIONS: Although diabetes generally causes chronic corneal edema, acute corneal edema may also occur when blood sugar is poorly controlled. Therefore, when we see sudden corneal opacity without obvious incentives, we must consider systemic diseases, especially diabetes.

摘要：
背景：角膜混浊可由各种疾病引起。一般来说,随着疾病的进展，混浊逐渐增加。突发性角膜混浊主要由角膜外伤引起,有毒药物进入角膜，或圆锥角膜的急性水肿。然而,糖尿病引起的突发性角膜混浊尚未见报道。
方法：一名60岁的男子报告视力模糊，左眼黑眼变白5天。该患者有糖尿病病史，未经治疗。
方法：他接受了裂隙灯检查，眼前节光学相干断层扫描，超声生物显微镜，B超,角膜内皮检查，随机血糖检测,和其他检查。诊断为糖尿病性角膜病变。
方法：给予局部糖皮质激素和扩张眼药水，并进行血糖控制治疗。
结果：患者的角膜在几天内完全透明，前房的絮状渗出消失了。
结论：尽管糖尿病通常会导致慢性角膜水肿，当血糖控制不佳时，也可能发生急性角膜水肿。因此,当我们看到突然的角膜混浊而没有明显的诱因时，我们必须考虑系统性疾病，尤其是糖尿病。
