Abstract

Objective: To estimate the prevalence of convergence insufficiency (CI) in adult patients with post-concussion syndrome and determine the impact of CI on symptom load.

Methods: Cross-sectional study of 103 patients with neurological symptoms 2-6 months after a concussion. Symptoms were assessed with the Rivermead Post Concussion Symptoms Questionnaire (RPQ), and CI was diagnosed using near point of convergence, vergence facility, and the Convergence Insufficiency Symptom Survey. The RPQ score for patients with and without CI was compared, and sensitivity, specificity, and area under the receiver operating characteristic curve for the two visually related RPQ questions as indicators of CI were calculated.

Results: The proportion of patients diagnosed with symptomatic CI was 20.4% (95% confidence interval: 13.1-29.5%). The RPQ score was significantly higher for patients with symptomatic CI both before (p = .01) and after removal of the two visually related questions in the RPQ-questionnaire (p = .03). The two visually related RPQ questions were unable to detect CI.

Conclusion: In patients with post-concussion syndrome, the load of nonvisual symptoms is higher in the presence of CI. A prospective interventional study on CI is required to study the relationship between CI and other post-concussion symptoms.

脑震荡后综合征患者的辐辏功能障碍伴有较重的症状负荷：一项横断面研究。

目的估算成年脑震荡后综合征患者辐辏功能障碍（CI）的患病率，并确定 CI 对症状负荷的影响：方法：对 103 名脑震荡后 2-6 个月出现神经症状的患者进行横断面研究。使用里弗米德脑震荡后症状调查表（RPQ）对症状进行评估，并使用辐辏近点、辐辏设施和辐辏功能障碍症状调查表对 CI 进行诊断。比较了有 CI 和无 CI 患者的 RPQ 得分，并计算了作为 CI 指标的两个视觉相关 RPQ 问题的敏感性、特异性和接收器操作特征曲线下面积：被诊断为无症状 CI 的患者比例为 20.4%（95% 置信区间：13.1-29.5%）。在去除 RPQ 问卷中两个视觉相关问题之前（p = .01）和之后（p = .03），无症状 CI 患者的 RPQ 得分均明显较高。这两个与视觉相关的 RPQ 问题无法检测出 CI：结论：在脑震荡后综合征患者中，如果存在 CI，非视觉症状的负荷会更高。需要对 CI 进行前瞻性干预研究，以研究 CI 与其他脑震荡后症状之间的关系。
