The short- and long-term results of recession-resection surgery on 141 exotropic patients were analyzed. The corrected angle of exodeviation one week after surgery was not affected by age at surgery, state of binocular vision or the type of intermittent exotropia. The corrected exodeviation was larger when the pre-operative exodeviation exceeded 30 prism diopters or when previous surgery had been performed. Since there was no difference between the angle of deviation at 4 and 8 years postoperatively, the period of four years was considered to be appropriate for long-term assessment. Post-operative exophoria of less than 15 prism diopters were obtained in patients whose short-term results were overcorrected or were under 5 prism diopters of exodeviation. The surgical guideline for exotropia should be determined considering the short-term and the long-term prognosis. It was concluded that the optimal time for surgery was between 5 and 10 years of age.
分析了141例外斜视患者行退缩-切除术的短期和长期结果。术后1周的矫正外斜视角不受手术年龄、双眼视状态或间歇性外斜视类型的影响。术前外斜超过30棱镜度或曾行手术时，矫正外斜更大。由于术后4年和8年的斜视角度无差异，因此认为4年时间适合进行长期评估。短期结果为过矫或外斜小于5棱镜度的患者术后可获得小于15棱镜度的外隐斜。应综合短期和长期预后确定外斜视的手术指南。结论是手术的最佳时机为5至10岁。
