BACKGROUND
Atropine, specifically 0.05% eyedrops, has proven effective in slowing myopia progression. This study aims to investigate peripheral refraction (PR) characteristics in myopic children treated with 0.05% atropine eyedrops at different frequencies.
METHODS
One hundred thirty-eight myopic children completed this one-year prospective study, randomly assigned to once daily (7/7), twice per week (2/7), or once per week (1/7) groups. Spherical equivalent (SE) and axial length (AL) were measured. PR was assessed using a custom-made Hartmann-Shack wavefront peripheral sensor, covering a visual field of horizontal 60° and vertical 36°. Relative peripheral refraction (RPR) was calculated by subtracting central from peripheral measurements.
RESULTS
After one year, SE increased more significantly in the 1/7 group compared to the 7/7 group (P < 0.001) and 2/7 group (P = 0.004); AL elongation was also greater in the 1/7 group compared to the 7/7 group (P < 0.001). In comparison with higher frequency groups, 1/7 group exhibited more myopic PR in the fovea and its vertical superior, inferior, and nasal retina; and less myopic RPR in the periphery retina after one-year (P < 0.05). Additionally, RPR in the 7/7 group demonstrated myopic shift across the entire retina, the 2/7 group in temporal and inferior retina, while the 1/7 group showed a hyperopic shift in the superior retina (P < 0.05). Moreover, myopic shift of RPR in the temporal retina is related to less myopia progression, notably in the 7/7 group (P < 0.05).
CONCLUSIONS
Atropine inhibits myopia progression in a frequency-dependent manner. The once-daily group showed the slowest myopia progression but exhibited more myopic shifts in RPR. Additionally, RPR in the temporal retina was related to myopia progression in all groups.

背景
阿托品，特别是0.05%的眼药水，已被证明对减缓近视进展有效。本研究旨在调查不同频率使用0.05%阿托品眼药水治疗的近视儿童的周边屈光（PR）特征。
方法
138名近视儿童完成了这项为期一年的前瞻性研究，随机分为每日一次（7/7）、每周两次（2/7）或每周一次（1/7）组。测量等效球镜度（SE）和眼轴长度（AL）。使用定制的哈特曼-夏克波前周边传感器评估PR，覆盖水平60°和垂直36°的视野。相对周边屈光（RPR）通过周边测量值减去中央测量值来计算。
结果
一年后，与7/7组（P < 0.001）和2/7组（P = 0.004）相比，1/7组的SE增加更为显著；与7/7组相比，1/7组的AL伸长也更大（P < 0.001）。与高频组相比，1/7组在黄斑及其垂直上方、下方和鼻侧视网膜表现出更多的近视性PR；一年后周边视网膜的近视性RPR更小（P < 0.05）。此外，7/7组的RPR在整个视网膜呈现近视性偏移，2/7组在颞侧和下方视网膜呈现近视性偏移，而1/7组在上方视网膜呈现远视性偏移（P < 0.05）。此外，颞侧视网膜RPR的近视性偏移与近视进展较慢有关，特别是在7/7组（P < 0.05）。
结论
阿托品以频率依赖的方式抑制近视进展。每日一次组的近视进展最慢，但RPR表现出更多的近视性偏移。此外，所有组中颞侧视网膜的RPR与近视进展有关。
