To report a case of a traumatic corneal endothelial ring sustained from a nonblast injury and its resolution with corneal optical coherence tomography (OCT) imaging.
The authors present a report of the clinical case with imaging of the lesion using corneal OCT.
A 59-year-old man presented 1 day after sustaining a nonpenetrating foreign body injury to his cornea. Slit-lamp examination showed an endothelial annular lesion of 3.3 mm in diameter, which was grey-white in color. No other signs of traumatic injury were present. Stromal edema and endothelial disruption were demonstrated on corneal OCT. This resolved completely on review.
We describe a concussive injury that specifically disrupts endothelial cells in an annulus on the perimeter of the impact zone. This results in transient stromal edema immediately anterior to the injured endothelial cells. These OCT findings corroborate previous animal studies on the mechanism and sequelae of injury.
报告一例因非爆炸伤导致的外伤性角膜内皮环,并通过角膜光学相干断层扫描(OCT)成像对其进行解析。
作者报告了一例临床病例,并使用角膜 OCT 对病变进行成像。
一名 59 岁男性在遭受角膜非穿透性异物伤后 1 天就诊。裂隙灯检查显示直径为 3.3 毫米的角膜内皮环形病变,呈灰白色。无其他外伤性损伤迹象。角膜 OCT 显示基质水肿和内皮细胞破坏。复查时完全消退。
我们描述了一种震荡性损伤,该损伤会在外伤作用区周边形成特定的角膜内皮细胞环形破裂,导致受损内皮细胞前的基质立即水肿。这些 OCT 发现与先前关于损伤机制和后遗症的动物研究结果相符。
