To evaluate the effect of epiblepharon surgery on visual acuity and with-the-rule astigmatism in children compared to patients without surgical treatment.
We undertook a retrospective case control study and reviewed the charts of 202 eyes treated with epiblepharon surgery and of 142 eyes without surgery. The surgical procedure for epiblepharon correction used rotating suture techniques. Data regarding age, best corrected visual acuity, and degree of astigmatism were recorded. Baseline and 1-, 3-, 6-, and 12-month postoperative data were collected. The chi-square test, Student's t-test and general linear model analysis for repeated measures were applied.
The mean astigmatism in the surgical group decreased from 1.10 ± 1.02 diopter (D) preoperatively to 0.84 ± 1.05 D at 3 months after surgery (p < 0.05). However, there was no statistically significant difference compared to the non-surgical group during the first year. The general linear model analysis comparing the mean astigmatism between the two groups over time showed a significant group-time interaction (p < 0.05). Within the surgical group, the higher baseline astigmatic subgroup and the 5- to 8-year-old group demonstrated greater cylinder reduction over time. The change in mean visual acuity was not significant in either group.
Significant astigmatic reduction was found after surgical correction in epiblepharon patients. Patients with higher baseline astigmatism exhibited greater astigmatic reduction after epiblepharon surgery. These results suggest that, in order to reduce astigmatism, an epiblepharon operation should be considered in patients with a high level of astigmatism.
评估与未接受手术治疗的患者相比，睑缘内翻手术对儿童视力和顺规散光的影响。
我们进行了一项回顾性病例对照研究，查阅了202只接受睑缘内翻手术治疗的眼睛以及142只未接受手术治疗的眼睛的病历。睑缘内翻矫正手术采用旋转缝线技术。记录有关年龄、最佳矫正视力和散光度数的数据。收集基线以及术后1个月、3个月、6个月和12个月的数据。应用卡方检验、学生t检验和重复测量的一般线性模型分析。
手术组的平均散光度数从术前的1.10±1.02屈光度（D）降至术后3个月时的0.84±1.05 D（p<0.05）。然而，与非手术组相比，在第一年期间差异无统计学意义。比较两组随时间变化的平均散光度数的一般线性模型分析显示，组-时间交互作用显著（p<0.05）。在手术组中，基线散光度数较高的亚组以及5至8岁组随时间推移散光度数降低更为明显。两组的平均视力变化均不显著。
睑缘内翻患者手术矫正后散光度数显著降低。基线散光度数较高的患者睑缘内翻手术后散光度数降低更为明显。这些结果表明，为了降低散光度数，对于散光度数较高的患者应考虑进行睑缘内翻手术。
