限制性斜视的特征和手术

目的：探讨限制性斜视的临床特征及手术。方法：对24例28眼视网膜手术后和7例9眼甲状腺相关性免疫眼眶病(简称TRIO)所致的限制性斜视病人，应用三棱镜加交替遮盖或三棱镜映光法(Krimsky法)测定斜视角，进行眼球运动及复视像检查，并观察该斜视手术的治疗效果。结果：1．限制性斜视的主要临床特征是斜视的方向均与主要牵制肌肉相一致，而与复视像分离最大方位和眼球运动受限最大方位则相反。2．限制性斜视手术后可以消除或改善复视，尤其是有效解决了第一眼位和阅读位的斜视。结论：1．限制性斜视的临床特征有助于指导对限制的肌肉做出准确判断和定位并进行斜视手术。2．斜视手术可改善复视症状、矫正眼位。

Clinical characteristics and surgery of restricted strabismus

Objective: To investigate the clinical features and surgical treatment of restricted strabismus. Methods: 24 cases (28 eyes) of constant strabismus following retina surgery and 7 cases (9 eyes) of restricted strabismus complicated by thyroid-related immune orbitopathy (TRIO) were examined under prism alternative cover test or Krimsky test,eyeball movement and diplopia analyses before and after strabismus operation.The effects of the operation on the restricted strabismus were also observed. Results: The main feature of restricted strabismus was that the direction of strabismus corresponded with the extraocular muscles restricted,and opposed to the most position in diplopia and restricted binocular motility.Strabotomy could completely or partly eliminate diplopia,especially could correct the restricted strabismus in primary position and in read location. Conclusions: The clinical characteristics of restricted strabismus are helpful for the accurate judgment on the orientation of restricted muscles,and helpful for the strabismus operation.Strabotomy is effective in the treatment of restrictive strabismus.
