目的：目的：探讨与日本单纯屈光性内斜视患者（包括屈光型和非屈光型）立体视远期疗效相关的临床因素。研究方法：回顾性分析了在冈山大学附属医院随访10年以上的19例（8男11女）纯反射性内斜视患者的病历。屈光性消隐性内斜视8例，非屈光性消隐性内斜视11例。根据最终访视时TNO测试测量的120弧秒或更好与240弧秒或更差的立体视锐度，将患者分为两组，并比较两组之间的临床因素。结果如下：与最后一次访视时立体视锐度为240弧秒或更差相关的临床因素是6岁时较高的矫正会聚与调节（AC/A）比值（p = 0.05），8岁时戴眼镜完全矫正时远距离残余内斜视较大（p = 0.03），并且在接近6岁时具有较大的残余内偏（p = 0.01，Mann-Whitney U检验）。总体而言，与屈光性屈光性内斜视患者相比，非屈光性屈光性内斜视患者在最终访视时的立体视锐度水平往往较差（p = 0.059，Fisher精确概率检验）。结论：这是第一个对日本单纯屈光性内斜视患者（包括屈光性和非屈光性）的长期视力结果进行的研究。为了获得更好的立体视锐度水平，在使用眼镜（包括双焦点眼镜）进行完全矫正的情况下，应尽可能减少近距离和远距离的残余内斜视，特别是在6岁和8岁时。
Purpose: To find clinical factors related to the long-term outcome of stereoacuity in Japanese patients with pure accommodative esotropia, including both the refractive type and the nonrefractive type. Methods: The medical charts of 19 Japanese patients (8 boys and 11 girls) with pure accommodative esotropia who were followed for 10 years or more at Okayama University Hospital were reviewed retrospectively. Refractive accommodative esotropia was diagnosed in 8 patients while nonrefractive accommodative esotropia was diagnosed in 11 patients. The patients were divided into two groups, based on a stereoacuity of 120 seconds of arc or better versus 240 seconds of arc or worse as measured by the TNO test at the final visit, and the clinical factors were compared between the two groups. Results: Clinical factors related to a stereoacuity of 240 seconds of arc or worse at the final visit were higher accommodative convergence to accommodation (AC/A) ratios at 6 years of age (p = 0.05), larger residual esodeviations at distance under full correction with glasses at 8 years of age (p = 0.03), and larger residual esodeviations at near at 6 years of age (p = 0.01, Mann-Whitney U-test). Overall, patients with nonrefractive accommodative esotropia tended to show poor levels of stereoacuity at the final visit compared to those with refractive accommodative esotropia (p = 0.059, Fisher exact probability test). Conclusion: This is the first study of the long-term visual outcome in Japanese patients with pure accommodative esotropia including both refractive and nonrefractive types. To obtain better levels of stereoacuity, the residual esodeviations at near and at distance should be kept as small as possible under full correction with glasses, including bifocals, especially at the ages of 6 and 8 years.
