ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the rule of the rebuilding of binocular vision after surgery in strabismus for thyroid-associated ophthalmopathy.</p><p><b>METHOD</b>The binocular vision was examined and compared in 30 patients before and after strabismus surgeries.</p><p><b>RESULTS</b>The strabismus degrees were 20-80(delta) before surgeries and 2-12(delta) 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(0) [mean (6.1 +/- 4.7)0] before strabismus surgeries and was 0-30(0) [mean (14.4 +/- 5.1)0] 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 < or = 60", 2 patients 80-200", and 4 patients 300-800"; while the post-surgery stereoacuity was as follows: 4 patients < or = 60", 6 patients 80-200", and 10 patients 300-800" (P < 0.05).</p><p><b>CONCLUSION</b>Strabismus surgeries for thyroid-associated ophthalmopathy can effectively improve ocular movement and rebuilt binocular vision.</p>
