Abstract:PURPOSE: To compare changes in superficial retinal vascular density (SRVD), deep retinal vascular density (DRVD), and重复低级红光(RLRL)和0.01%阿托品暴露后,黄斑区的视网膜厚度(RT)。p> 方法: 前瞻性随机试验。六十九个具有环读折射的学童> -0.75 d和≤0.50d被随机分配给RLRL和0.01%的阿托品基团。 SRVD,DRVD和RT是在基线和六个月时使用扫描源光学相干断层扫描测量的。 The macular zone was divided into three concentric rings (fovea, parafovea, and perifovea) using the Early Treatment Diabetic Retinopathy Study.
RESULTS: After six months, the whole, parafoveal, and perifoveal SRVD significantly increased in the two groups (all P<0.05).多变量回归分析表明,两组之间这些变化均未显着变化(所有p> 0.05),而foveal SRVD在两组中保持稳定(所有P> 0.05)。在RLRL组中,整个和perifoveal DRVD显着增加(所有p <0.05),而在中央凹和p中未观察到统计差异Arafoveal Drvd。 DRVD在0.01%的阿托品组中保持稳定(全p> 0.05)。两组之间的RT变化未观察到显着差异(所有p> 0.05)。 In comparison, there were no significant changes in SRVD, DRVD, or RT after six months in the placebo group in our previous study.
CONCLUSIONS: SRVD increased similarly in the RLRL and 0.01% atropine groups, whereas DRVD increased only in the former group.在六个月的治疗中,这两组均无显着变化。
转化相关性: 这项研究观察到低级红光的影响,低水平的红光和0.01%垂直于视网膜气管血管的效果预防。
