目的 :探讨V型斜视不同术式 ,以求达到矫正斜视 ,消除V征 ,建立双眼视功能目的。方法 :按V征上下斜角差的大小分为 <2 0 Δ、 2 0～ 30 Δ、 >30 Δ 三组 ,分别采用水平直肌垂直移位 ,下斜肌减弱及下斜肌减弱加水平直肌垂直移位三种术式 ,分别矫正上下斜角差异不同的V型斜视。结果 :以上术式不仅矫正了水平斜视 ,消除V征 ,而且可能建立和恢复原在位及阅读眼位双眼单视功能。结论 :水平直肌垂直移位 ,下斜肌减弱及下斜肌减弱加水平直肌垂直移位三种方法能达到矫正眼位的目的 ,术后测定远近立体视锐度 ,对双眼单视功能及疗效的评价有重要意义。
Objective: To investigate the different types of strabismus in V-shaped strabismus in order to achieve the purpose of correcting strabismus, eliminating V sign and establishing binocular visual function. Methods: According to the difference of the upper and lower bevel angles of V-V, the vertical displacement of horizontal rectus muscle, the decrease of inferior oblique muscle and the decrease of inferior oblique muscle were respectively divided into <2 0 Δ, 2 0 ~ 30 Δ,> 30 Δ. Rectus muscle vertical displacement of three kinds of surgery, respectively, different upper and lower bevel correction of V-type strabismus. Results: The above procedures not only correct horizontal strabismus, V sign, and may establish and restore the original position and read binocular binocular vision. Conclusion: The vertical rectus abdominis, the lower oblique hypothalamic and the lower oblique lower extremity horizontal rectus muscle vertical displacement of the three methods to achieve the purpose of correcting the eye position, postoperative determination of near and far stereoacuity, single binocular vision And the evaluation of efficacy is of great significance.
