A new surgical procedure, the proximal levator technique, achieves recession of the retracted upper eyelid in Graves' ophthalmopathy by sectioning the levator muscle proximal to Whitnall's ligament and fixing eyelid position with sutures that permit postoperative adjustment. This technique deserves further study. Enlargement of the proximal levator muscle in Graves' eye disease is shown on orbital CT scans and is found at surgery when the proximal levator technique is employed. Histologic and morphometric studies demonstrate increased levator muscle fiber size as well as increased extracellular volume. These findings suggest that levator muscle hypertrophy is important in the pathogenesis of upper eyelid retraction in Graves' ophthalmopathy.
一种新的外科手术方法，即提上睑肌近端技术，通过在惠特纳尔韧带近端切断提上睑肌并用允许术后调整的缝线固定眼睑位置，使格雷夫斯眼病中退缩的上睑得以复位。该技术值得进一步研究。格雷夫斯眼病患者的眶部CT扫描显示提上睑肌近端增大，在采用提上睑肌近端技术进行手术时也能发现这一情况。组织学和形态计量学研究表明，提上睑肌纤维大小增加以及细胞外体积增大。这些发现提示，提上睑肌肥大在格雷夫斯眼病上睑退缩的发病机制中起重要作用。
