摘　　要：目的探讨持续近距离阅读相同内容的纸质文本和电子文本对健康青年人黄斑区微循环产生的短期影响。方法前瞻性使用光学相干断层扫描血管成像(OCTA)测量2021年5—10月就读于潍坊医学院的30名(60眼)健康在校大学生阅读纸质文本和电子文本1 h前后,黄斑区浅层视网膜血流密度(SVD)、深层视网膜血流密度(DVD)及脉络膜血流密度(CVD)和黄斑中心凹下脉络膜厚度(SFCT)的变化并进行对比。结果经过量化分析,阅读纸质文本1 h,SVD在中心凹的下降[(18.3±7.4)%,(17.4±7.2)%]和旁中心凹下方区域的下降[(50.2±4.2)%,(48.0±5.5)%],差异有统计学意义(Z=2.93,P=0.021;Z=3.25,P=0.007);在其他的采集区域中,干预前后SVD的改变差异无统计学意义(P>0.05)。阅读电子文本1 h后,CVD下降[(75.8±4.1)%,(74.7±4.9)%](t=2.36,P=0.022);SFCT下降(289.0±6.2,280.7±6.6)(t=2.35,P=0.022)。结论持续近距离阅读纸质文本1 h,会引起黄斑区浅层视网膜血流在短期内下降;持续近距离阅读电子文本1 h,会引起黄斑区脉络膜血流在短期内下降。这会增加一些眼底疾病的发病率。Objective To investigate the short-term effects of sustained close reading of paper and electronic texts with the same con⁃tent on macular microcirculation in healthy young people.Methods In this prospective study,optical coherence tomography angiogra⁃phy(OCTA)was used to measure superficial capillary plexus vessel density(SVD),deep capillary plexus vessel density(DVD),choroi⁃dal capillary vessel density(CVD)and subfoveal choroidal thickness(SFCT)in the macular region before and after 1 h of reading paper text and electronic text in 30(60-eye)healthy university students enrolled in Weifang Medical College from May 2021 to October 2021.Results After quantitative analysis,reading paper text for 1 hour,SVD decreased in the center concave[(18.3±7.4)%,(17.4±7.2)%]and in the area regions of the paracentral concave[(50.2±4.2)%,(48.0±5.5)%],with statistically significant differences(Z=2.93,P=0.021;Z=3.25,P=0.007).While after reading the e-text for 1 h,the CVD decreased[(75.8±4.1)%,(74.7±4.9)%](t=2.36,P=0.022);the SFCT decreased(289.0±6.2,280.7±6.6)(t=2.35,P=0.022).Conclusions Continuous close reading of paper text for 1 h caused a short-term decrease in superficial retinal blood flow in the macula;continuous close reading of electronic text for 1 h caused a short�term decrease in choroidal blood flow in the macula.This can increase the incidence of some fundus diseases.
