结局指标
主要结局
Number of Participants With Symptom Success at 10 Weeks
时间窗: 10 weeks after enrollment
In the convergence insufficiency group, the primary outcome will be symptom success at the 10-week and 12-month visit, defined as improvement of CI Symptom Survey (CISS) score of at least 9 points and an outcome score of \<21 points. In the divergence insufficiency group, the primary outcome will be symptom success at the 10-week and 12-month visit, defined as diplopia "rarely" or "never" in primary position at distance on the diplopia questionnaire. In the small-angle hypertropia group, the primary outcome will be symptom success at the 10-week and 12-month visit, defined as diplopia "rarely" or "never" both in primary position at distance and in reading position on the diplopia questionnaire.

时间窗: 12 months after enrollment
In the convergence insufficiency group, the primary outcome will be symptom success at the 10-week and 12-month visit, defined as improvement of CI Symptom Survey (CISS) score of at least 9 points and an outcome score of \<21 points. In the divergence insufficiency group, the primary outcome will be symptom success at the 10-week and 12-month visit, defined as diplopia "rarely" or "never" in primary position at distance on the diplopia questionnaire. In the small-angle hypertropia group, the primary outcome will be symptom success at the 10-week and 12-month visit, defined as diplopia "rarely" or "never" both in primary position at distance and in reading position on the diplopia questionnaire.
