Of 650 patients who underwent various surgical procedures on the anterior segment in which 2% lidocaine hydrochloride plus 1:100,000 epinephrine was used as a local anesthetic, 5 experienced postoperative complications attributed to the anesthetic: ptosis (in 2 cases), horizontal rectus muscle palsy (in 2) and lagophthalmos (in 1). The cause of the complications may have been inadvertent direct infiltration of the anesthetic into the levator palpebrae superioris, the horizontal rectus muscles and the orbicularis oculi respectively. All the patients recovered spontaneously in 8 to 12 weeks. The clinical course was compatible with myotoxic effects of local anesthetics.
在650例接受前段各种外科手术的患者中，使用2%盐酸利多卡因加1:100,000肾上腺素作为局部麻醉剂，有5例出现了归因于麻醉剂的术后并发症：上睑下垂（2例）、水平直肌麻痹（2例）和兔眼症（1例）。并发症的原因可能分别是麻醉剂意外直接浸润到提上睑肌、水平直肌和眼轮匝肌中。所有患者均在8至12周内自发恢复。临床病程与局部麻醉剂的肌毒性作用相符。
