A report covering 80 cases of esophoria in which surgery was performed. All the patients had previously suffered from severe headache and other complaints. Preoperative treatment consisted of full prismatic correction. The power of the prisms was measured by the "Polatest" method. We observed that the increase of the angle was initially very slow; sometimes two years or more were needed for it to reach 15 degrees. Subsequently the angle increased rapidly, stabilizing a few months later, whereupon surgery was performed. The peroperative angle varied from 15 degrees to 56 degrees. Postoperatively most cases attained orthophoria, some others a residual esophoria; there were only three cases of exophoria, these being among the 14 cases who had to undergo surgery twice. Sixty percent of the patients were subsequently free of complaints and the rest, with two exceptions, showed a distinct improvement. The average follow-up period was 2.2 years after surgery. One may conclude that esophorias which give rise to complaints can be treated with prisms, but that some of them may have to be operated on. For successful treatment a reliable instrument for measuring the angle of the phoria is indispensable. We found the Polatest best for this purpose. In most cases orthophoria and permanent relief of symptoms will result.
一份关于80例实施手术的内隐斜病例的报告。所有患者此前都患有严重头痛及其他不适症状。术前治疗包括完全棱镜矫正。棱镜的度数采用“Polatest”方法测量。我们观察到，角度增加最初非常缓慢；有时需要两年或更长时间才能达到15度。随后角度迅速增加，几个月后稳定下来，随即进行手术。手术时的角度在15度至56度之间变化。术后大多数病例达到正位视，其他一些病例有残余内隐斜；只有3例外隐斜，这些病例在14例需要接受二次手术的患者之中。60%的患者随后没有不适症状，其余患者除两例外，均有明显改善。术后平均随访期为2.2年。可以得出结论，引起不适症状的内隐斜可用棱镜治疗，但其中一些可能需要手术。为成功治疗，可靠的隐斜角度测量仪器必不可少。我们发现Polatest最适合此用途。在大多数情况下，将实现正位视并永久缓解症状。
