集合不足及其研究进展

Convergence insufficiency and its research progress

随着现代文明的发展,电子产品的使用和阅读成为生活中不可或缺的一部分。长期近距离用眼容易导致眼疲劳,可能发生在不同年龄段人群,包括幼儿、学生、成年人及老年人。因此,眼科临床工作者在处理近距离用眼疲劳的患者时,需要了解并认识相关问题。近距离用眼疲劳常见的原因之一是集合不足,是一种常见的非斜视性双眼视功能异常,常见的视疲劳症状有眼疼、头疼、视物模糊、重影、复视、眼干等,严重时会出现恶心、呕吐等现象,严重干扰人们的日常生活。然而目前临床工作中,对集合不足的认识和重视不够。集合不足的检查方法及诊断标准不同文献及临床大夫把握的也不一致,可能导致部分集合不足患者没有获得及时、恰当的治疗。现从集合不足的定义、病因、诊断及治疗新进展进行综述,进一步认识集合不足。

With the development of modern civilization,the use and reading of electronic product have become an indispensable part of our lives.Long-time near work usually causes asthenopia,which may occur in different age groups,including young children,students,adults and the elderly.Therefore,it is necessary for ophthalmologists to understand and recognize these problems when dealing with patients with asthenopia.One of the common causes of asthenopia is convergence insufficiency(CI),which is a common non-strabismic binocular dysfunction.The typical symptoms of eyestrain include eye pain,headache,blurred vision,double vision,dry eyes,etc.It can also cause nausea and vomiting in severe cases,which have a profound impact on a person’s quality of life.However,CI is not routinely screened by all clinicians.The examination methods and diagnostic criteria of CI are not consistent in the literature and practice.As a result,some patients may receive delayed diagnosis and therapy.In this article,the definition,etiology,diagnosis and treatment of CI were reviewed to further understand CI.
