To report a case of inadvertent intracorneal injection of anesthetic agents during lid anesthesia and corneal penetration without full-thickness perforation.
Case report.
Corneal edema with acute loss of vision was noted. The patient was treated with topical, antibiotic, cycloplegic, hyperosmotic agent and lubricant. While the edema slowly subsided, a loss in endothelial cell count was noted.
The effects of intracorneal injection of lignocaine, bupivacaine, and its preservatives have not previously been reported in the literature. A lower postinjection endothelial cell count and associated clinical features in our case indicate that endothelial toxicity occurred. This potential complication should be kept in mind with necessary precautions taken during injection of the eyelid, particularly in cases with preexisting lid laxity.
报告一例在施行眼睑麻醉时意外将局麻药注入角膜而未导致全层穿孔的病例。
病例报告。
患者出现角膜水肿伴视力急性丧失。局部应用抗生素、睫状肌麻痹剂、高渗剂和润滑剂进行治疗。尽管水肿逐渐消退，但内皮细胞计数下降。
利多卡因、布比卡因及其防腐剂注入角膜的影响尚未在文献中报道。在我们的病例中，注射后内皮细胞计数降低以及相关的临床特征表明发生了内皮毒性。在施行眼睑注射时应牢记这种潜在的并发症，并采取必要的预防措施，尤其是在存在眼睑松弛的情况下。
