结膜囊收缩是眼球摘出后常见的一种晚期并发症,可致义眼不能安装。有些病例似由于下睑板回转成水平状,致使义眼下缘滑脱(图1)。类似的情况也见于睑板外翻,此可能由于下直肌和下睑部眼轮匝肌收缩引起下睑板沿睑板韧带水平方向外转所致。作者报告一种矫正无眼球的下睑板回转的手术方法如下。距下睑缘3—4毫米,平行睑板下缘,水平切开下睑皮肤,分离开皮肤与眼轮匝肌,再加深切开眼轮匝肌(图2),借睑金属板压迫结膜面,找到下睑板下缘。有时须沿睑板下缘的结膜面作一切开。切断向内牵引睑板的纤维组织(图1,
Contraction of the conjunctival sac is a common late complications after enucleation, can cause the eye can not be installed. In some cases, the lower edge of the lower eyelid turns into a horizontal shape, causing the lower edge of the eyelid to slip (Figure 1). A similar situation is also seen in eversion of the tarsal plateaus, which may be due to lateral lower rotation of the lower tarsal plate along the horizontal tarsal ligaments due to contraction of the orbicularis oris muscle of the lower eyelid. The authors report that a surgical procedure for correcting non-ocular lower tarsal rotation is as follows. 3-4 mm from the lower eyelid, parallel to the lower edge of the tarsus, horizontal incision of the skin of the lower eyelid, separated from the skin and orbicularis oculi muscle, and then deepen the orbicularis oculi (Figure 2), by eyelid metal sheet compression conjunctiva Face, find the lower edge of the lower tarsal plate. Sometimes along the lower edge of the tarsal conjunctiva to make everything open. Cut the tarsal traction within the fibrous tissue (Figure 1,
