近视儿童主导眼相关因素研究

Research on related factors of dominant eye in myopic children

目的:探讨近视儿童主导眼与屈光度、眼别、裸眼视力的关系。方法:随机抽取经散瞳检影验光后,待瞳孔恢复正常复诊配镜患儿99例,用卡洞法检查主导眼,进行分类统计分析。结果:在99例近视患儿中,以右眼为主导眼,即右型(Rtype)者占66.7%(66/99),两者比较差异有显著统计学意义(P=0.0001);当双眼屈光度不相等时,以屈光度相对较低眼为主导眼者42例(52.5%),两者比较差异无统计学意义(P=0.527);当双眼屈光度相等时,以右眼为主导眼,占68.4%,两者比较差异具有统计学意义(P=0.0231);在双眼裸眼视力不等64例中,以裸眼视力低眼为主导眼者34例(53.1%),两者差异无统计学意义(P=0.4795);在双眼裸眼视力相等35例中,右眼为主导眼29例(82.9%),两者比较差异极具统计学意义(χ2=30.2286,P<0.01)。结论:近视儿童主导眼以右型多见,主导眼与屈光度、裸眼视力高低的相关性差异无统计学意义。

AIM： To explore the relationship of myopic children＇s dominant eye, diopter, classes of eye and uncorrected visual acuity. METHODSL Totally 99 cases of children with their pupil back to normal after glasses were randomly selected after cycloplegic retinoscopy. The dominant eye was checked with hole-in-the-card test, classified and statistically analyzed. RESULTS= In 99 cases of myopic children,the right eye as the dominant eye, namely right type （R type） accounted for 66. 7% （66/99）, the difference was statistically significant （ P = 0. 0001 ） . when eye refraction was not equal ,the eye of a relatively low refraction acted as the dominant eye in 42 cases （52.5%）, there was no significant difference between the two types （ P = 0. 527） ; when the eye refractive power was equal, the right eye as the dominant eye accounted for 68. 4%, the difference was statistically significant （ P = 0. 0231 ） ; in 64 patients with different uncorrected visual acuity in both eyes,the eye of low visual acuity acted as the dominant eye in 34 eyes （53.1%）, no significant difference between the two types （P = 0. 4795） ; in 35 cases of equal visual acuity in both eyes, right eye acted as dominant eye in 29 cases （82. 9%）, it was of highly statistically significant difference （X2 = 30.2286, P〈0.01）. CONCLUSION： The R type dominant eye is common in the eyes of myopic children. For the relevance of dominant eye refraction, and also uncorrected visual acuity level, the difference was not statistically significant.
