摘要
目的:评估传统与欠矫手术治疗部分调节性内斜视患者的效果。方法:将25例具有部分调节性内斜视和正常AC/A的患者随机分为两组,其中13例患者接受传统手术治疗,其余12例患者接受欠矫手术治疗。传统手术是基于远距远视完全矫正所测量的偏差上,而欠矫手术比传统手术标准低20%。所有患者均进行对称性双眼内直肌后退术,术后随访6mo。结果:术后6mo,传统组与欠矫组手术成功率分别为46%和91%(成功标准定义为通过近距和远距远视的完全矫正斜视≤8△)。传统组和欠矫组的手术过矫率分别为54%和9%,两组间差异有统计学意义(P<0.05)。没有残余内斜视。手术成功率或欠矫率与患者的年龄、术前等效球镜均值、术前眼偏斜量无相关性。结论:对于具有正常AC/A的部分调节性内斜视患者,欠矫的双眼内直肌后退术成功率较高,过矫率较低。
AIM: To evaluate the efficacy of standard and undercorrected surgical methods in patients with partially accommodative esotropia (PAET).
METHODS: Twenty-five patients with PAET and normal accommodative convergence/accommodation ( AC/A ) were divided into two groups for alternate surgical plan including standard method (13 patients) and undercorrected method (12 patients) in a randomized fashion. Standard method is based on measured deviation through full hyperopic correction at distant target and was performed by Parks scheme. Undercorrected method criteria is 20% lower than standard. All patients underwent symmetrical bilateral medial rectus recessions (BMR), and all of them were followed for 6 months.
RESULTS: Six months after operation, surgical success (defined as tropia ≤ 8^△ at distant and near fixation through full hyperopic correction) was 46% in standard group and 91% in undercorrected group. Overcorrection were observed 54% in standard group and 9% in undercorrected group ( P 〈 0.05). There was no residual esotropia. There was no correlation between surgical success rate or overcorrection rate and age, mean of preoperative spherical equivalent or preoperative eye deviation.
CONCLUSION: Undercorrected BMR surgery has a lower overcorrection rate and higher surgical success rate than standard surgery in patients with PAET and normal AC/A.
