人工眼位散开术治疗婴儿眼球震颤综合征(附6例报告)

目的 探讨人工眼位散开术(ADS)治疗婴儿眼球震颤综合征(INS)的疗效。方法 回顾性病例研究2012年3月至2014年9月采用ADS治疗的有集合阻滞的INS患者。患者均行矫正视力检查,采用整形量角器测量患者注视5 m调节性视标时的代偿头位,采用Worth四点灯检查患者融合功能,采用Titmus立体视图测定其看近立体视锐度,均行三棱镜耐受试验并行双侧内直肌后徙3~4 mm。结果 6例INS患者接受ADS治疗,术后随访3~12月,平均9.8个月。其中,术后代偿头位4例治愈,1例改善,1例无效;术后单眼和双眼矫正视力3例提高,3例无改变;术后立体视锐度2例提高,4例不变。术后眼位过矫1例。结论 ADS对有集合阻滞的INS有较好的疗效,但有发生继发性外斜视的风险。

Outcome of artificial divergence surgery in patients with infantile nystagmus syndrome (6 cases report)

Objective To investigate the outcome of artificial divergence surgery in patients with infantile nystagmus syndrome. Methods Six infantile nystagmus syndrome patients with blocking convergence enrolled in out department from March 2012 to September 2014 were retrospectively evaluated. Corrected visual acuity was measured respectively. The head turn (HT) was measured when patients staring at distance fixation using a goniometer. Binocular vision function of patients was evaluated by the Titmus Stereo Test and the Worth Four Light Test in appropriate refractive correction. Prism adaptation test was used in all patients pre-operatively. The amounts of bilateral medial rectus recession was 3-4 mm. Results The average post-operative follow-up period was 9.8 months (range, 3-12 months). After surgery, the HT was eliminated in 4 patients, improved in 1 patient and ineffective in 1 patient. Monocular and binocular corrected visual acuity was improved in 3 patients and unchanged in 3 patients. Stereopsis acuity was improved in 2 patients and unchanged in 4 patients. 1 patient was consecutive exotropia. Conclusion The results of this study preliminarily showed artificial divergence surgery was effective to INS patients with blocking convergence.
