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。
OBJECTIVE: To evaluate the efficacy of traditional and undercorcompanied partial esophagectomy in patients with accommodative esotropia. Methods: Twenty-five patients with partial regulatory esotropia and normal AC / A were randomly divided into two groups, of whom 13 received conventional surgery and the remaining 12 received undercorrection. Conventional surgery is based on the measured deviation from complete correction of distance hyperopia, whereas undercorrection surgery is 20% lower than traditional surgical criteria. All patients were symmetrical binocular rectus retraction, postoperative follow-up 6mo. RESULTS: At 6 months postoperatively, the successful rates of surgery were 46% and 91%, respectively (the success criterion was defined as complete correction of strabismus by distance and distance hyperopia ≤ 8 Δ). The overcorrection rates of the traditional and undercorrection groups were 54% and 9%, respectively, with significant differences between the two groups (P <0.05). No residual esotropia. There was no correlation between the success rate of surgery and the rate of undercorrection with the age of patients, mean spherical equivalent before operation, and preoperative eye deviation. Conclusion: For patients with partial accommodative esotropia with normal AC / A, undercorrection of the rectus medialis rectus has a high success rate and a low overcorrection rate.
