目的。确定学龄儿童会聚功能不全（CI）和调节功能不全（AI）的发生率，并评估CI、AI、视力症状和散光之间的关系。方法：3 - 8年级学生完成会聚功能不全症状调查（CISS）和双眼视力测试，并在规定的情况下进行矫正。根据散光程度（无/低：<1.00 D，中等：1.00 D至<3.00 D，高：≥3.00 D）、是否存在CI和AI临床体征以及是否存在症状对学生进行分类。分析确定临床CI和AI、症状CI和AI的发生率，并评估CI、AI、视觉症状和散光之间的关系。结果。在484名学生（11.67±1.81岁）中，症状性CI为6.2%，症状性AI为18.2%。AI在有CI的学生中比没有CI的学生更常见。只有AI的学生（p = 0.02）和有CI和AI的学生（p = 0.001）的症状得分高于没有CI和AI的学生。中度和高度散光不增加CI或AI的风险。结论。有规则的散列不会增加CI或AI的风险。CI和AI的高合并率以及AI的高症状评分表明，需要研究确定CI特有的症状学。
Purpose. To determine rate of convergence insufficiency (CI) and accommodative insufficiency (AI) and assess the relation between CI, AI, visual symptoms, and astigmatism in school-age children. Methods. 3rd–8th-grade students completed the Convergence Insufficiency Symptom Survey (CISS) and binocular vision testing with correction if prescribed. Students were categorized by astigmatism magnitude (no/low: <1.00 D, moderate: 1.00 D to <3.00 D, and high: ≥3.00 D), presence/absence of clinical signs of CI and AI, and presence of symptoms. Analyses determine rate of clinical CI and AI and symptomatic CI and AI and assessed the relation between CI, AI, visual symptoms, and astigmatism. Results. In the sample of 484 students (11.67 ± 1.81 years of age), rate of symptomatic CI was 6.2% and symptomatic AI 18.2%. AI was more common in students with CI than without CI. Students with AI only (p = 0.02) and with CI and AI (p = 0.001) had higher symptom scores than students with neither CI nor AI. Moderate and high astigmats were not at increased risk for CI or AI. Conclusions. With-the-rule astigmats are not at increased risk for CI or AI. High comorbidity rates of CI and AI and higher symptoms scores with AI suggest that research is needed to determine symptomatology specific to CI.
