A retrospective study of 179 patients (69 males and 110 females) with binocular visual dysfunction and an exodeviation at distance or near or at both distances has been completed. The mean age of 19.7 years was significantly younger than the population from which they were referred. The patients were classed as convergence insufficiency, equal exodeviation, or divergence excess, based on the relation of the distance and near angles of deviation. Based on these criteria, interaction was found to be present between the diagnostic class and the frequency of the deviation, the symptoms reported, and a variety of clinical parameters such as the angles of deviation at distance and near, the AC/A ratio, positive and negative vergence values, the amplitude of accommodation, and the threshold of stereopsis. A number of statistical relations were noted between the frequency of the deviation vs. the symptoms reported and a variety of the clinical parameters. The implications of these results are discussed.
对179例双眼视功能障碍且存在远距离或近距离或远近均有外斜视的患者（69例男性和110例女性）进行了一项回顾性研究。这些患者的平均年龄为19.7岁，明显低于转诊来源人群的年龄。根据远距离和近距离斜视角度的关系，将患者分为集合不足、等量外斜视或分开过强。基于这些标准，发现诊断类别与斜视频率、所报告的症状以及各种临床参数（如远距离和近距离斜视角度、AC/A比率、正负融合值、调节幅度和立体视阈值）之间存在相互作用。在斜视频率与所报告的症状以及各种临床参数之间发现了一些统计关系。讨论了这些结果的意义。
