摘　　要：目的探讨不同方法测量AC/A值在眼视光诊疗中的应用效果。方法选择2018年5月—2020年12月眼视光中心配镜需求顾客75例作为研究对象,所有患者使用电脑验光加综合验光进行标准屈光检查;并完成患者视功能检查,对患者进行3个月随访,每个月完成一次复查或随访,于复查或随访期间分别采用隐斜法、梯度法、同视机法并分别附加不同调节刺激对患者AC/A值测量,并以临床最终矫正AC/A值作为金标准,分析不同方法所测结果是否相同及与调节反应的相关性。结果隐斜法测量AC/A值高于梯度法和同视机法(P<0.05);梯度法AC/A值高于同视机法(P<0.05);隐斜法近视距离注视33 cm下AC/A值低于隐斜法近视距离注视44 cm(P<0.05);梯度法在注视距离为33 cm和40 cm分别附加四组刺激镜片,分别加入-1.00D、-2.00D、+1.00D+2.00D,将两组中附加相同的刺激镜片所测得的AC/A值进行比较,但是差异无统计意义(P>0.05);同视机法分别附加-1.00D、-2.00D、-3.00D镜片,完成患者AC/A值测定,结果表明:不同镜片下AC/A值测量结果比较无统计意义(P>0.05)。结论隐斜法与梯度法相比,测得的AC/A值偏大;而隐斜法近用注视距离测得的AC/A值偏小;梯度法附加不同的镜片测得的AC/A值大小与所附加的镜片类型有关;而同视机法测量AC/A值是在视远状态下进行,测得结果接近真实值。因此,临床上梯度法附加正镜片完成AC/A值测量较为合适。Objective To explore the application effect of different measurement methods of AC/A value in optometry diagnosis and treatment.Methods 75 customers who needed eyeglasses in the optometry center from May 2018 to December 2020 were selected as objects.All patients underwent standard refractive examination with computer optometry and comprehensive optometry.The visual function examination of the patients was completed,and the patients were followed up for 3 months.The reexamination or follow-up was completed once a month.During the reexamination or follow-up,the implicit oblique method,gradient method and synoptophore method were used to measure the AC/A value of the patients with different regulatory stimuli,and the clinical final corrected AC/A value was taken as the gold standard to analyze whether the results measured by different methods were the same and their correlation with regulatory response.Results The AC/A value measured by implicit oblique method was higher than that measured by gradient method and synoptophore method(P<0.05).The AC/A value of gradient method was higher than that of synoptophore method(P<0.05).The AC/A value at 33 cm in the implicit oblique method was lower than that at 44 cm in the implicit oblique method(P<0.05).The gradient method added four groups of stimulating lenses at the fixation distance of 33cm and 40cm,the added stimulating lenses were-1.00D,-2.00D,+1.00D,and+2.00D,respectively.The AC/A values measured by adding the same stimulating lenses in the two groups were compared,however,the difference was not statistically significant(P>0.05).The patients'AC/A values were measured by adding-1.00D,-2.00D and-3.00D lenses respectively in synoptophore method.The results showed that there was no statistical significance in the measurement results of AC/A values under different lenses(P>0.05).Conclusions The AC/A value measured by implicit oblique method is larger than that measured by gradient method.The AC/A value measured by implicit oblique method with close fixation distance is re
