摘要:
METHODS: This study was a single-center randomized clinical trial. A total of 94 children with premyopia (- 0.50 D < spherical equivalent [SE] ≤ + 0.75 D) were randomly assigned to either the RLRL therapy or control group. Follow-up visits were planned at 1, 3, 6, 9, and 12 months. Optical coherence biometry was used to measure axial length (AL)和前部参数。 (PARAF)和PERIFOVEAL(PERIF)区域。
结果: 在整个黄斑区域中,在RLRL治疗组的不同时间点上观察到整个黄斑区域的脉络膜增厚。RLRL治疗的1个月随访时Y增加了(±标准偏差[SD])调整后的变化为16.96±19.87μm。在3个月的访问(增加19.58±20.59μm)时,观察到最大的中央凹CT变化,在6个月访问时Foveal CT的增加程度略有下降(增加了15.85±23.77μm)。在9个月的访问中观察到了第二大CT的增加(增加了19.57±35.51μm),此后,CT的增加程度逐渐下降,直到研究结束为12个月的访问(增加了11.99±32.66μm)。我们还观察到在12个月内,RLRL组的PARAF和PERIF区域的CT显着增加。相反,对照组中整个黄斑区域的CT在整个随访期间都显着降低(所有p <0.05)。关于脉络膜的血管参数,CVV的显着增加,主要在R脉络的PARAF和PERIF区域中观察到RLRL组。相比之下,对照组在整个区域中表现出CVV的降低。此外,在1个月(增加0.40 mm),3个月(增加了0.25 mm)和12个月的访问(增加了0.42 mm)(全p <0.05)中,在RLRL组的脉络膜区域中检测到CCPA的显着升高。另外,在整个12个月中,两组之间在中央凹RT和视网膜血管参数方面没有明显差异(p> 0.05)。 Notably, RLRL therapy achieved a notable reduction in SE shift by 73.8%, a substantial decrease in AL change by 67.9%, and a significant reduction in myopia incidence by 45.1% within 1 year.
CONCLUSION: Our study demonstrated a significant increase in CT and flow in the在整个研究的整个12个月中,RLRL处理的眼睛。结合其降低球形等效进展和轴向伸长,RLR可以用作预防较前进展的有效疗法。
