Two rare cases of strabismus resulting from contracture of the extraocular rectus muscles after retrobulbar anesthesia for cataract surgery are described. Clinical signs in both cases suggested that the development of the impaired function of the lateral and superior rectus muscles followed the same pattern: initial stimulation followed by paretic and restrictive stages. Abnormal enlargement of the muscles was identified by computed tomography (CT) and magnetic resonance imaging (MRI). The data indicate that the strabismus was the result of direct injection of anesthetics into the rectus muscle.
本文描述了两例白内障手术后球后麻醉导致眼外直肌挛缩引起斜视的罕见病例。两例患者的临床体征均提示，外直肌和上直肌功能障碍的发展遵循相同模式：最初为刺激期，随后进入麻痹期和限制期。通过计算机断层扫描（CT）和磁共振成像（MRI）确定肌肉异常增大。数据表明，斜视是由于麻醉剂直接注入眼直肌所致。
