Abstract

PURPOSE In this study we decided to answer the question of whether spending more time on reading and writing leads to higher prevalence of myopia. MATERIAL AND METHODS A total of 70 people (140 eyes)--17 men and 53 women aged 18-29 years (mean 22.5 ± 2.8) were examined. A questionnaire concerning the amount of time spent each day on reading and writing, as well as ophthalmic examination involving: visual acuity, anterior segment and fundus examination, keratometry, autorefractometry and axial length of the eyeball measurement (using IOL Master) were carried out in all participants. The refractive errors were described as spherical equivalents (SE). Hyperopia was defined to be SE higher than +0.5 Dsph, and emmetropia to be higher than -0.5 and lower than +0.5 Dsph. Myopia was defined to be with a SE lower than -0.5 Dsph. High myopia was defined as SE lower than -8, medium myopia in the range between -8 and -4, and low myopia lower than -0.5 and higher than -4 Dsph. The obtained results were typed into an Excel spreadsheet and analyzed statistically using Statistica 10 software. P values of < 0.05 were considered statistically significant. RESULTS It was found that people with low myopia spent statistically more time on reading and writing than participants in the emmetropic group (5.8 ± 2.4 vs 4.1 ± 2.4 h/day, p = 0.003). A relationship between reading and writing and medium and high myopia and hyperopia was not observed (p > 0.05). CONCLUSION Near visual work leads to higher prevalence of low myopia.
阅读和写作对近视患病率的影响。
目的:在这项研究中,我们决定回答是否花更多的时间在阅读和写作导致更高的近视患病率的问题。材料与方法共检查70人(140眼),其中男性17人,女性53人,年龄18-29岁(平均22.5±2.8)。对所有参与者进行了一份关于每天阅读和写作时间的问卷调查,并进行了眼科检查,包括:视力、前段和眼底检查、角膜测光、自动屈光和眼球轴长测量(使用IOL Master)。折光误差用球面等效(SE)表示。远视定义为SE高于+0.5 Dsph,远视定义为SE高于-0.5且低于+0.5 Dsph。近视定义为SE低于-0.5 Dsph。高度近视定义为SE低于-8,中度近视在-8到-4之间,低近视低于-0.5和高于-4 Dsph。将得到的结果输入到Excel电子表格中,并使用Statistica 10软件进行统计分析。P值< 0.05认为有统计学意义。结果低近视眼组在阅读和写作上花费的时间明显多于正视视组(5.8±2.4 h/d vs 4.1±2.4 h/d, p = 0.003)。阅读和写作与中、高度近视和远视之间无相关性(p > 0.05)。结论近视工作导致低近视发生率增高。
