摘要
目的:研究双眼视功能各参数中与视疲劳的发生有关系的参数,以发现在视疲劳中起重要作用的指标,为进一步通过视功能训练改善视疲劳症状提供基础。方法:通过问卷调查选取门诊患者50例,年龄11～37岁。其中,有视疲劳症状患者25例,无症状者25例。用综合验光仪进行主觉验光以及双眼视功能各项参数(隐斜视,AC/A,融合范围等)测定,并分析结果。结果:有视疲劳症状组与无症状组之间,视远及视近隐斜无统计学差异;AC/A值之间存在显著差异;融合范围无统计学差异。结论:视疲劳的发生与双眼视功能的异常有着密切的关系。调节性辐辏与调节的比值(AC/A)异常是视疲劳的一个最重要的因素。
AIM： To study the correlation of visual fatigue and phoria, AC/A, fusion function.
METHODS. Fifty persons aged 11-37 years old were included in this research. Twenty-five of them had visual fatigue symptoms, others were normal. We measured the diopter with phoropter and the parameters of binocular function, such as phoria, AC/A, fusion function, and analyzed the results.
RESULTS： Phoria and fusion function were no correlation with visual fatigue. Prominent statistics difference was found in AC/A in normal people and people with visual fatigue symptoms.
CONCLUSION： Abnormal of AC/A can cause the occurrence of visual fatigue.
