摘要
目的探讨一种比较精确的提上睑肌厚度的测量方法,从而对上睑下垂的手术治疗方法给与更为准确的指导。方法随机选择先天性单侧或双侧上睑下垂患者,并将所有眼分为正常、轻度、中度、重度四组,通过超声生物显微镜对各种程度上睑下垂患者的提上睑肌厚度进行测量,再与传统的上睑下垂分级方法进行比较。结果本组病例共42人,经测量四组平均值分别为0.478±0.037mm;0.383±0.038mm;0.381±0.042mm;0.339±0.035mm。统计学处理用单因素方差分析法,结果显示利用超声生物显微镜术前检查上睑提肌厚度各组间有明显差异(P<0.01)。讨论超声生物显微镜是一种比较精确的测量提上睑肌厚度的方法,此种测量方法可以有效的区分上睑下垂程度,可以为上睑下垂手术治疗方法的选择提供较为有效的依据。
Objective To evaluate one relatively accurate t of the thickness of the levator aponeurosis by ultrasound biomicroscopy, and to provide clinical guidance on the surgical treatment of blepharoptosis. Methods 84 upper eyelids of 42 bilateral or unilateral congenital dysmyogenic and aponeurotic blepharoptosis patients were measured by the clinical standards and categorized into normal, mild, moderate and severe group. Ultrasound biomicroscopy was applied to measure the thickness of levator of each eyelid and to see the if there are siguificent differences. Results The measurements of normal group （23 eyelids）, mild group （16 eyelids）, moderate group （19 eyelids）, and severe group （26 eyelids） are 0.478±0.037mm;0.383±0.038mm;0.381 ±0.1M2mm; 0.339±0.035mm respectively. Significant difference was found between the groups （P〈0.01）. Conclusions The thickness of the levator aponeurosis can be measured and grouped with ultrasound biomicroscopy which can provid clinical guidance on the surgical treatment of blepharoptosis.
