Although a few cases of dermatitis or keratitis caused by exposure to the sap of Euphorbia trigona have been reported, we present a rare case of transient corneal endothelial dysfunction following exposure to the sap, resulting in corneal edema. A woman in her 70s complained of reduced vision, redness, and teariness in her left eye 2 days after exposure to the sap of E. trigona at home. Upon examination, hyperemia, serious corneal edema, and anterior uveitis with hypopyon were observed in her left eye, without corneal epithelial defects or keratic precipitates. The best-corrected visual acuity (BCVA) was 2.0 (logarithm of the minimum angle of resolution), and the measured central corneal thickness (CCT) was 812 µm. The patient was treated with topical instillation of 1.5% levofloxacin and 0.1% dexamethasone to reduce intraocular inflammation and corneal edema. Three weeks later, the BCVA reached 0, the CCT was 519 μm, and the corneal endothelial cell density was 3,233 cells/mm2. Six months after the injury, the patient had good visual acuity, and the cornea was completely transparent. No recurrence of corneal edema or anterior uveitis was observed. Exposure to the sap of E. trigona can lead to severe corneal edema with anterior uveitis, impairing visual acuity. Taking precautions to prevent the exposure of the eye to the sap of this plant is crucial.

接触大戟树液后角膜水肿伴前葡萄膜炎:病例报告

虽然已经报道了一些因接触大戟属植物的汁液而导致皮炎或角膜炎的病例,但我们提出了一个罕见的病例,即接触大戟属植物汁液后短暂的角膜内皮功能障碍,导致角膜水肿。一名 70 多岁的妇女在接触E的汁液 2 天后抱怨左眼视力下降、发红和流泪。三角架在家里。经检查,左眼充血,角膜水肿严重,前葡萄膜炎伴前房积脓,无角膜上皮缺损或角膜沉淀。最佳矫正视力 (BCVA) 为 2.0(最小分辨率角的对数),测得的中央角膜厚度 (CCT) 为 812 µm。患者接受局部滴注 1.5% 左氧氟沙星和 0.1% 地塞米松以减轻眼内炎症和角膜水肿。三周后,BCVA达到0,CCT为519 μm,角膜内皮细胞密度为3,233个细胞/mm 2。伤后6个月,患者视力良好,角膜完全透明。没有观察到角膜水肿或前葡萄膜炎的复发。暴露于汁液trigona可导致严重的角膜水肿和前葡萄膜炎,损害视力。采取预防措施以防止眼睛接触到这种植物的汁液是至关重要的。
