摘要

目的：持續性瞳孔薄膜殘遺是相當常見的遺傳疾病。然而，此薄膜阻礙視軸和減低視力卻是不常見。為減低弱視的產生，我們利用外科方式以Stegmann剪刀移除持續性瞳孔薄膜殘遺，並且探討其結果。
方法：我們報告4位小孩7個眼睛（平均年齡5±0.8歲）有持續性瞳孔薄膜殘遺。術後追蹤時間從12個月至34個月（平均19±2.7月），此薄膜被Stegmann剪刀（角度25度，刀刃長1.7毫米，目錄編號612.21）小心切除，並利用微小鑷子從前房移除。
結果：手術後，所有七個眼睛視力都明顯改善，且瞳孔圓而美觀。並沒有白內障或眼壓上升的後遺症發生。
結論：嚴重的持續性瞳孔薄膜殘遺可明顯地降低視力並引起弱視，然而利用外科方式以Stegmann剪刀移除此膜，可顯著地提昇患者的視力。

Purpose: Persistent pupillary membranes (PPMs) are common congenital disorders. However, the membranes, occluding the visual axes and resulting in reduced visual acuity, are relatively uncommon. To reduce the amblyopia, we used Stegmann scissors to remove the persistent pupillary membrane and reviewed the surgical result.
Methods: We report 7 eyes from four children (mean age 5±0.8 years) with extensive persistent pupillary membranes. The post-operative follow-up period ranged from 12 months to 34 months (mean 19±12.7 months). The membrane strands were carefully cut with the Stegmann scissors (Angle 25 Length of blade 1.7 mm, Cat. No. 612.21), and removed from the anterior chamber with micro forceps.
Results: After surgery, visual acuities were improved and pupillary apertures were round and cosmetically good in all of the 7 eyes. No complications were found including cataract formation or elevation of the intraocular pressure.
Conclusions: The persistent pupillary membranes sufficiently dense enough to cause a significant reduction in vision and amblyopia. Improvement of acuity could be achieved by using the surgical removal of Stegmann scissors.
