摘要
目的调查近视患者的视疲劳的流行率,研究近视患者视疲劳的发生与眼动参数的关系,进而探讨近视患者视疲劳与双眼视功能异常的关系。方法本研究测量800例近视患者在屈光不正矫正下的各眼动参数,包括调节功能:调节幅度(AA),调节灵敏度(AF),调节反应和双眼视功能:近距离垂直和水平隐斜,远近距离的正负融像集合(NFV&PFV),辐辏近点(NPC),正负相对调节(NRA&PRA),刺激性AC/A和立体视。结果 800例近视患者中有视疲劳194例(24.3%),不同年龄和屈光度比较差异无统计学意义(P>0.05),而女性(27.8%)高于男性(19.4%),差异有统计学意义(P<0.05);戴眼镜视疲劳患病率(24.1%)低于非戴眼镜患病率(39.2%),差异具有统计学意义(P<0.05)。24.3%的近视患者报告有视疲劳,视疲劳组和非视疲劳组之间的单眼调节幅度、双眼调节幅度、正相对调节和负相对调节差异有统计学意义(P<0.05)。结论近视患者视疲劳的发生与调节幅度,正负相对调节的降低有关,并且与较高的AC/A值可能有关系。
Objective To determine the prevalence of asthenopia in myopes patients and the relationship between visual function parameters and asthenopia in myopes,and investigate the relationship between binocular dysfunction and the presence of asthenopia in myopes.Methods The study population included 800 cases,myopic refractive error correction eye movement parameters were investigated,including regulation function;the amplitude of accommodation（AA）,adjust the sensitivity（AF）,adjust the response and binocular vision;close vertical and horizontal phoria,near and far from the positive and negative financial like collection（NFV PFV）,vergence near point（NPC）,positive and negative relative accommodation （NRA PRA）,irritating AC/A and stereoscopic vision..Results 800 cases of myopia visual fatigue in 194（24.3%） patients,different ages and diopter difference was not statistically significant（P〈0.05）,and women（27.8%） more than men（19.4%）,the difference was statistically significance（P〈0.05）;wearing glasses eye asthenopia prevalence rate （24.1%） than non-glasses prevalence rate（39.2%）,the difference was statistically significant（P〈0.05）.24.3%of myopia patients report visual fatigue,the asthenopia group and non-visual fatigue group between monocular amplitude of accommodation, binocular accommodative amplitude positive relative accommodation and negative relative accommodation difference was statistically significant（P〈0.05）.Conclusion Myopia visual fatigue was related with occurrence and amplitude of accommodation, reduce of positive and negative relative accommodation,and may have relationship with high AC/A value.
