To report the effectiveness of home-based pencil push-ups (HBPP) therapy for patients with symptomatic convergence insufficiency.
Data was collected prospectively on 16 patients who were diagnosed with convergence insufficiency beginning in January 2009. The study group was composed of ten male and six female patients. The duration of symptoms, refractive error, distant and near deviation angles, and near point of convergence (NPC) prior to and after 12 weeks of HBPP therapy were measured in all patients.
The mean age of the patients was 19.3 years. The mean deviation angle of exophoria was 3 prism diopters (PD) at distant and 11.2 PD at near. The mean value of NPC prior to HBPP therapy was 36.3 cm; however, the near point of accommodation was within the normal range. After 12 weeks of HBPP therapy, the mean deviation angle of exophoria decreased to orthophoric at distant and 4 PD at near. The mean value of NPC decreased to 14.4 cm.
Twelve weeks of HBPP therapy appears to be an easy, cost-free and effective therapy for patients with symptomatic convergence insufficiency.
报告家庭式铅笔俯卧撑（HBPP）疗法对有症状性集合不足患者的有效性。
前瞻性收集了自2009年1月起被诊断为集合不足的16例患者的数据。研究组由10名男性和6名女性患者组成。测量了所有患者在HBPP治疗12周前后的症状持续时间、屈光不正、远近距离偏斜角以及集合近点（NPC）。
患者的平均年龄为19.3岁。外隐斜的平均偏斜角在远距离时为3棱镜度（PD），在近距离时为11.2 PD。HBPP治疗前NPC的平均值为36.3 cm；然而，调节近点在正常范围内。HBPP治疗12周后，外隐斜的平均偏斜角在远距离时降至正位，在近距离时降至4 PD。NPC的平均值降至14.4 cm。
对于有症状性集合不足的患者，12周的HBPP治疗似乎是一种简便、免费且有效的治疗方法。
