目的.尽管一些作者报告说，在临床人群中非老视的一般双眼功能障碍（非斜视）的患病率高于除屈光不正以外的任何疾病，但支持这一说法的研究有限。这项临床研究确定了这些条件的存在和临床意义，在人口的大学生与沉重的近视觉需求。方法.从一组二年级学生谁得到了彻底的眼睛检查，65名学生被选中。选择标准是没有明显的未矫正屈光不正，健康的眼睛，没有斜视或弱视。结果32.3%的受试者表现为一般性双眼功能障碍。在10.8%的病例中，存在过量的稀释剂。7.7%有会聚不足伴会聚过度。6.2%表现为舒张功能不全。3.1%有基础性外隐斜。会聚过度伴屈光不全、基础性斜视和融合性聚散功能障碍的患病率均为1.5%。结论.在这一人群中，屈光不正和非斜视性双眼视觉问题普遍存在。过度兴奋是最常见的症状。由于这些功能障碍可能对表现产生负面影响，因此对该人群进行适当的视力评估非常重要。
Purpose. Although some authors report that the prevalence of general binocular dysfunctions (nonstrabismic) for nonpresbyopes in the clinical population is greater than any condition except refractive error, limited research is available to support this statement. This clinical study determined the presence and clinical implications of these conditions in a population of university students with heavy near visual demands. Methods. From a group of second year students who were given a thorough eye examination, 65 students were selected. The criteria for selection were the absence of significant uncorrected refractive error, healthy eyes, and no strabismus or amblyopia. Results. 32.3% of the subjects showed general binocular dysfunctions. In 10.8% of the cases, accommodative excess was present. 7.7% had convergence insufficiency with accommodative excess. 6.2% showed accommodative insufficiency. 3.1% had basic exophoria. Convergence excess with accommodative insufficiency, basic esophoria, and fusional vergence dysfunction all showed the same prevalence of 1.5%. Conclusions. Accommodative and nonstrabismic binocular vision problems are prevalent in this population. Accommodative excess is the most common condition. Because these dysfunctions may have a negative effect on performance, appropriate vision evaluation for this population is important.
