Horizontal Transposition of the Vertical Rectus Muscles to Treat Cyclotorsion-A Case Report

垂直直肌水平移位治療旋位斜視-病例報告

摘要


垂直直肌水平移位可治療旋位斜視及斜頸。一位60歲男性,左眼旋位複視,眼底像片有20度外旋。我們做左上直肌全肌肉寬度顳側移位,左下直肌全肌肉寬度鼻側移位,得到滿意的療效。在此病人,每條肌肉移位產生10度的旋位效果。此一術式的重點在於,移位後肌肉端和角膜緣的距離必需和原肌肉相等。我們懷疑此一術式若合併肌肉後徙術,將使其治療旋位的效果大減。

Horizontal transposition of the vertical rectus muscles was proposed as a surgical procedure to treat ocular torticollis and cyclotropia. A 60 year-old male patient had left eye torsional diplopia. Fundus photograph showed 20 degrees excyclotorsion. We did LSR a muscle-width temporal transposition and LIR a muscle-width nasal transposition to get satisfactory result. In our patient, each muscle transposition corrected10 degrees excyclotorsion. The key point of this procedure is that the muscle ends should be sutured at equidistance from the limbus as the original insertion. We doubt this procedure will be much less effective if combined with recession.
