摘　　要：目的通过比较睫状肌麻痹前后散光度数及其矢量成分的变化,探讨睫状肌麻痹对散光的影响。方法横断面研究。随机选取2018年5月至2020年1月在惠州市第三人民医院视光专科就诊并同意参加本研究的成人近视患者261例(18~48岁),对其进行眼轴、小瞳综合验光、睫状肌麻痹下(复方托吡卡胺滴眼液)综合验光仪主觉验光检查。收集被检者年龄、性别、眼轴、睫状肌麻痹前后屈光度数,并采用配对t检验对睫状肌麻痹前后散光度数及各矢量变化进行分析。每例均取右眼进行统计分析。结果所有被检的261例均完成本研究。睫状肌麻痹后,等效球镜度数减少了(0.37±0.47)D(P<0.05)。在本研究中睫状肌麻痹前后柱镜度数≥0.25 D的人数为243例,占93.1%。散光类型以顺规散光为主,其后依次为斜轴散光、逆规散光。睫状肌麻痹后高度散光比例稍有增加,从37.13%增加到40.33%,同时高度散光组中顺规散光比例从71.13%增加到了77.55%。但是睫状肌麻痹前后,散光度数及各矢量成分的变化均无统计学意义。结论对成人近视患者而言,散光检出率高,且以顺规散光为主。睫状肌麻痹可降低等效球镜度数,但对散光度数及各矢量成分影响并不明显。Objective To investigate the effect of cycloplegia on astigmatism in adults with myopia by comparing the changes in astigmatic power and its vector components.Methods In this prospective cross-sectional study,261 myopic adults were randomly selected from the optometry department of the Third People's Hospital of Huizhou from May 2018 to January 2020,and informed consent was obtained from all participants.Axial length and subjective optometry were recorded pre-and post-cycloplegia by phoropter subjective optometry.Statistical analyses were performed in terms of subjects’age,gender,axis length,and refraction.All the data from the right eye and were analyzed by the paired t-test.Results A total of 261 subjects completed this study.The spherical equivalent refraction(SE)of post-cycloplegia was decreased by 0.37±0.47 D(P<0.05).Of all 261 subjects,there were 243 subjects with cylinder over 0.25 D(pre-and post-cycloplegia),accounting for 93.1%.The type of astigmatism was mainly with-the-rule(WTR),followed by oblique axis astigmatism and then against-the-rule astigmatism(ART).After cycloplegia,the proportion of high astigmatism increased from 37.13%to 40.33%,and the proportion of WTR astigmatism in the high astigmatism group increased from 71.13%to 77.55%.But the changes of the astigmatic power and the vector components were not statistically different.Conclusions In this study,there was a high prevalence of astigmatism in myopic adults,and was predominantly WTR.The spherical equivalent refraction was lower after cycloplegia,but the effects of cycloplegia on astigmatic power and its vector component were not significant.
