The Convergence Insufficiency Symptom Survey (CISS) is a questionnaire used as an outcome measure in treatment of convergence insufficiency. The current prospective randomized trial evaluates the diagnostic specificity of the CISS.
Surveys were completed by 118 adolescent patients who presented for routine eye examinations. Scores were compared between patients who could be classified as having convergence insufficiency (CI) or normal binocular vision (NBV). In addition, a comparison was done between self-and practitioner-administered CISS scores within these groups.
The mean CISS score did not differ significantly between NBV patients (14.1±11.3, range of 0 to 43) and CI patients (12.3±6.7, range of 3 to 28); P=0.32. Mean CISS scores were lower when physician-administered (11.4±7.9) than when self-administered (16.3±11.4); P=0.007.
CISS scores tend to be higher when self-vs. practitioner-administered. This study suggests that the CISS questionnaire is not specific for convergence insufficiency.
集合不足症状调查（CISS）是一种用于集合不足治疗效果评估的问卷。当前的前瞻性随机试验评估了CISS的诊断特异性。
118名前来进行常规眼科检查的青少年患者完成了调查。对可分类为患有集合不足（CI）或双眼视力正常（NBV）的患者的得分进行了比较。此外，还对这些组内自我填写和由医生填写的CISS得分进行了比较。
NBV患者（14.1±11.3，范围为0至43）和CI患者（12.3±6.7，范围为3至28）的CISS平均得分无显著差异；P = 0.32。由医生填写时的CISS平均得分（11.4±7.9）低于自我填写时的得分（16.3±11.4）；P = 0.007。
自我填写的CISS得分往往高于由医生填写的得分。本研究表明，CISS问卷对集合不足缺乏特异性。
