随着年龄的增长，人的调节功能逐渐降低，融合机制功能减弱，使本来有外隐斜的患者发生失代偿。当外隐斜＞４°时，双眼单视受到干扰出现视疲劳症状，甚至出现复视。对工作学习影响极大，为解除此类患者之苦，我们采用融合训练法对其进行矫治以增强其辐辏功能，扩大融合范围，消除视疲劳症状，保持双眼单视功能。结果７～１４岁年龄组融合范围：训练前分开－４．５２±３８８，辐辏＋６５３±４４２；训练后分开－５４６±５４９，辐辏＋１８．６４±８．５２，Ｐ＜０．０１。１５～５１岁年龄组融合范围：训练前分开－４．５０±１．９８，辐辏＋４．４３±２．３２。训练后分开－５．２５±１．９４，辐辏＋２０．５０±７．４９，Ｐ＜０．０１，接受治疗者融合范围扩大，视疲劳症状消失，应用同视机训练辐辏融合功能治疗外隐斜是消除外隐斜致视疲劳的有效方法。
With age, people’s regulatory function gradually decreased, the function of the fusion mechanism weakened, so that patients with exocrine hypotension have been decompensated. When the extraverted oblique> 4 °, binocular monochromatic interference appear as visual fatigue symptoms, and even diplopia. Great impact on the work of learning, in order to relieve the suffering of such patients, we use the fusion training method to treat it to enhance its convergence function, to expand the scope of integration, to eliminate visual fatigue symptoms, to maintain binocular vision function. Results The range of fusion in 7 ~ 14 age group was: -4.52 ± 3.88 before training, and 653 ± 442 before training; -546 ± 549 after training, and .6 18.64 ± 8. 52, P <0.01.15 ~ 51 years old group fusion range: -4.50 ± 1.98 before training, and 43 4.43 ± 2.32. After training, -5.25 ± 1.94 and rectus + 20.50 ± 7.49, P <0.01, the fusion range of the treated patients enlarged and the symptoms of visual fatigue disappeared. Oblique oblique angle is to eliminate extraocular oblique visual fatigue as an effective method.
