摘　　要：目的探讨甲状腺相关眼病限制斜视手术后双眼视功能重建规律。方法对30例甲状腺相关眼病限制斜视患者手术前、后行双眼视功能检查并进行比较。结果30例患者手术前斜视度为20～80Δ,手术后2～12Δ。双眼视功能检查,手术前有重合点的19例(63.3%)、无重合点的11例(36.7%);手术后有重合点的28例(93.3%)、无重合点的2例(6.7%)。手术前融合范围0～120,平均(6.1±4.7)0;手术后融合范围0～300,平均(14.4±5.1)0,两者比较差异具有显著性(P<0.001)。手术前有立体视觉的9例(30%)、无立体视觉的21例(70%);手术后有立体视觉的22例(73.3%)、无立体视觉的8例(26.7%)。立体视锐度手术前≤60″无、手术后增至4例;手术前80～200″2例、手术后增至6例;手术前300～800″4例、手术后增至10例,立体视锐度手术前后差异具有显著性(P<0.05)。结论甲状腺相关眼病限制斜视手术治疗在改善眼位的同时,双眼视功能得以重建。Objective To evaluate the rule of the rebuilding of binocular vision after surgery in strabismus for thyroid-associated ophthalmopathy. Method The binocular vision was examined and compared in 30 patients before and after strabismus surgeries. Results The strabismus degrees were 20-80^Δ before surgeries and 2-12^Δ after surgeries. As shown by synoptophores examinations, 19 patients （63.3%） had degree one before strabismus surgeries and the number increased to 28 （93.3 % ） after the surgeries. Synoptophore fusion area was 0-12° [ mean （6. 1 ± 4. 7 ）° ] before strabismus surgeries and was 0-30° [ mean （ 14.4 ± 5.1 ）° ] after the surgeries （P 〈0. 001 ）. Nine patients （30%） had stereovision before strabismus surgeries, and the number increased to 22 （73.3%） after the surgeries. Pre-surgery stereoacuity was as follows： none ≤60″, 2 patients 80-200″, and 4 patients 300-800″; while the post-surgery stereoacuity was as follows： 4 patients ≤ 60″, 6 patients 80-200″, and 10 patients 300-800＂ （P 〈 0.05）. Conclusion Strabismus surgeries for thyroid-associated ophthalmopathy can effectively improve ocular movement and rebuilt binocular vision.
