手术治疗伴有斜视的先天性冲动型眼球震颤

Surgical treatment to idiopathic congenital nystagmus with strabismus

目的探讨先天性冲动型眼球震颤合并斜视的手术治疗方法及效果。方法回顾性分析行手术治疗的先天性冲动型眼球震颤伴有斜视11例,所有患者均根据中间带位置、代偿头位、斜视角度和注视眼的关系进行中间带的移位以及斜视的矫正。结果9例术后代偿头位完全改善,1例术后残留15°面转角,1例残留10°上斜视,所有患者原在位视力均提高两行以上。结论通过中间带移位及斜视度叠加矫正斜视,可以明显改善先天性冲动型眼球震颤的代偿头位及外观,并能提高第一眼位的双眼视力。

Objective To evaluate the method and effect of surgery on idiopathic congential nystagmus with strabismus. Methods A retrospective study to 11 patients of eongenital nystagmus with strabismus was reviewed. All patients received bilateral rectusmuscle recessions and resections based on the main eye ; their degrees of strabismus and head posture. Results 9 cases look in the front direction without nystagmus or with slight nystagmus. The head posture became nominal. The post - operative eyeball positionwas essentially normal by light of the nine patients. The head posture had residua of 15 degree in one case. The post-operative eyeball position had residua of 10 degree by light. All cases could see more than two lines better than before Conclusion Surgery of bilateral rectue muscle recessions and resections can improve the strabismus and compensatary head posture of congential nystagmus effectively so as to improve visual acuity in primary position.
