Carotid-cavernous fistula (CCF) is a rare condition involving an abnormal communication between the carotid artery and the cavernous sinus. We present a unique case of posttraumatic unilateral CCF initially misdiagnosed as a corneal melt with iris prolapse and orbital cellulitis. The patient, a 25-year-old male, experienced swelling, bleeding, and sudden vision loss in the affected eye following a fall. Imaging confirmed a direct CCF, and the patient underwent endovascular coiling, evisceration, and prosthetic replacement. Partial loss of levator palpebrae superioris muscle function was observed postprocedure. This case underscores the diagnostic challenge of CCF and highlights the significance of early and accurate diagnosis for appropriate management.
颈动脉海绵窦瘘（CCF）是一种罕见的病症，涉及颈动脉与海绵窦之间的异常连通。我们报告了一例独特的创伤后单侧CCF病例，最初被误诊为角膜溶解伴虹膜脱垂和眼眶蜂窝织炎。该患者为一名25岁男性，跌倒后患眼出现肿胀、出血和突然失明。影像学检查证实为直接CCF，患者接受了血管内栓塞、眼球摘除和假体置换。术后观察到上睑提肌部分功能丧失。该病例强调了CCF的诊断挑战，并突出了早期准确诊断对于适当治疗的重要性。
