本研究的目的是在我们最初的验证性研究中，评估研究者偏见是否影响双眼视力正常儿童的会聚不足症状调查(CISS)得分，重新评估16分分界点的有用性，并重新检验CISS的有效性。参加汇聚性功能不全治疗试验(CITT)的六个临床站点招募了46名9-18岁的NBV儿童。戴着面具的检查员对孩子的双目视觉状况进行了CIS检查。CITT中221名有症状的CI儿童的平均CISS评分与最初的非掩蔽性CISS研究中NBV儿童的平均CISS评分进行了比较。46例NBV患者的平均(±SD)Ciss评分为10.4(±8.1)分。这与我们之前的非掩蔽性NBV研究的结果相似(平均值=8.1(±6.2)；p=0.11)，但与CITT CI组的平均值(平均值=29.8±9.0；p<；0.001)有显著差异。在这些NBV受试者中，83%的人在CIS上的得分低于16分，这与最初的非掩蔽研究中发现的87.5%的得分没有统计学差异(p=0.49)。在我们先前的研究中，考官偏见并不影响NBV受试者的CSIS分数。CI仍然是量化9-18岁儿童症状的有效工具，这些结果证实了≥16在区分有症状的CI和NBV儿童方面的有效性。
The objectives of the present study were to evaluate whether investigator bias influenced the Convergence Insufficiency Symptom Survey (CISS) scores of children with normal binocular vision (NBV) in our original validation study, reevaluate the usefulness of the cut-off score of 16, and reexamine the validity of the CISS. Six clinical sites participating in the Convergence Insufficiency Treatment Trial (CITT) enrolled 46 children 9 - <18 years with NBV. Examiners masked to the child’s binocular vision status administered the CISS. The mean CISS score was compared to that from the children with NBV in the original, unmasked CISS study and also to that of the 221 symptomatic CI children enrolled in the CITT. The mean (±SD) CISS score for 46 subjects with NBV was 10.4 (±8.1). This was comparable to that from our prior unmasked NBV study (mean = 8.1(± 6.2); p = 0.11), but was significantly different from that of the CITT CI group (mean = 29.8 ± 9.0; p < 0.001). Eighty-three percent of these NBV subjects scored less than 16 on the CISS, which is not statistically different from the 87.5% found in the original unmasked study (p = 0.49). Examiner bias did not affect the CISS scores for subjects with NBV in our prior study. The CISS continues to be a valid instrument for quantifying symptoms in 9 to <18 year-old children and these results confirm the validity of a cut-point of ≥ 16 in distinguishing children with symptomatic CI from those with NBV.
