Myasthenia gravis is typically a disease of young people in active employment who need a field of binocular single vision. Although it is systemically controllable with a good chance of spontaneous remission, persistent loss of binocularity may cause chronic disability. We report our experience of extraocular muscle surgery in five patients with stable myasthenia gravis and persistent double vision. Extraocular muscle involvement was selective, giving rise to incomitant and concomitant squints, with individual muscle overactions as well as underactions. Treatment was by conventional recession and resection procedures with the additional use of Faden and adjustable sutures where appropriate. In all five cases a larger, stable field of binocular single vision was established. It is concluded that extraocular muscle surgery may be beneficial in selected cases of myasthenia gravis.
重症肌无力通常是处于工作年龄段的年轻人所患的疾病，这些患者需要双眼单视视野。尽管该疾病在系统上是可控的，且有自发缓解的良好机会，但双眼视功能的持续丧失可能导致慢性残疾。我们报告了5例重症肌无力病情稳定但仍有持续性复视患者的眼外肌手术经验。眼外肌受累具有选择性，导致非共同性斜视和共同性斜视，伴有个别肌肉的亢进和功能不足。治疗采用传统的后徙和切除术，并在适当情况下额外使用缝线固定术和可调节缝线。在所有5例患者中，均建立了更大、更稳定的双眼单视视野。结论是，眼外肌手术在某些重症肌无力病例中可能有益。
