Abstract：
The aim of this study is to test the hypothesis that margin-reflex distance 1 (MRD1) on the day of surgery will be higher than the MRD1 measured at the in-clinic consult visit among patients undergoing blepharoptosis repair due to an increased sympathetic drive.
Patients evaluated for involutional blepharoptosis repair were prospectively enrolled over a 12-month period in this single-center, self-controlled study. Three investigators independently determined MRD1 using cropped photos taken of patients at the in-clinic consult visit and on the day of surgery. A difference in height was tested for by using the 2-tailed Wilcoxon signed rank test.
Evaluated in this study were 76 eyelids from 38 patients. Over 3-quarters of study participants had a higher MRD1 in the right and OSs on the day of surgery than at their in-clinic consultation visit (p < 0.001). The mean increase in MRD1 for the right eyelid and left eyelid was 1.0 mm (range: 0-3.15 mm) and 1.1 mm (range: 0-2.7 mm), respectively.
In patients with involutional blepharoptosis, we conclude that MRD1 is higher on the day of surgery as compared with the in-clinic consult visit. This may be secondary to the stress of surgery and an associated increase in sympathetic drive. In some cases, this change in eyelid position led to resolution of apparent involutional ptosis altogether. Caution should be used when considering deferral of ptosis repair on the basis of exam findings present on the day of surgery.

摘要：
目的：本研究的目的是验证以下假设：在因交感神经驱动增加而进行上睑下垂修复的患者中，手术当天的边缘反射距离1（MRD1）将高于在临床咨询就诊时测得的MRD1。
方法：在该单中心的12个月期间，前瞻性地纳入了被评估为进行性上睑下垂修复的患者，自我对照研究。三名研究人员使用在临床咨询访问和手术当天拍摄的患者裁剪照片独立确定了MRD1。通过使用2尾Wilcoxon符号秩检验来测试身高差异。
结果：本研究评估了38例患者的76个眼睑。超过3/4的研究参与者在手术当天的右侧MRD1和OS高于他们的临床咨询访问（p<0.001）。右眼睑和左眼睑的MRD1平均增加为1.0mm（范围：0-3.15mm）和1.1mm（范围：0-2.7mm），分别。
结论：在内卷性上睑下垂患者中，我们得出的结论是,与临床咨询就诊相比,手术当天的MRD1较高.这可能是次要的手术压力和相关的交感神经驱动的增加。在某些情况下,眼睑位置的这种变化导致明显的内卷性上睑下垂完全消退。根据手术当天的检查结果，考虑推迟上睑下垂修复时应谨慎使用。
