【Purpose】To retrospectively compare the effects of orthokeratology (OK) and atropine eye drops at 0.01% (AT) for myopia progression prevention.
【Subjects and Methods】Subjects were patients with axial length of 23.5 mm to 26.5 mm, who had received OK or AT initiated between the age of 7-15 years and had been followed up for at least 2 years. A total of 15 eyes of 15 patients in the OK group and 14 eyes of 14 patients in the AT group were included. Using the axial length at the third month after the start of the treatment as a baseline, the amount of axial length change was compared between the two groups every six months for two years. Only the right eye was investigated in this study.
【Results】Before treatment, the respective average axial lengths and age for the OK and AT groups were 24.73±0.5 mm and 24.65±0.6 mm, and 10.27±2.3 years and 10.86±2.2 years. No significant differences were observed between both groups (p = 0.230 for axial length, p = 0.466 for age). The respective amounts of axial length changes for the OK and AT groups were 0.11±0.08 mm and 0.14±0.16 mm at 6 months, 0.20±0.09 mm and 0.34±0.25 mm at 12 months, and 0.27±0.12 mm and 0.46±0.34 mm at 18 months. No significant differences in the amount of axial length change were observed between both groups (p = 0.615 at 6 months, p = 0.121 at 12 months, and p = 0.081 at 18 months). In the second year of the treatment, the AT group showed a significantly larger amount of axial length change (0.57±0.36 mm) than the OK group (0.30±0.12 mm) (p = 0.046).
【Conclusion】It was suggested that orthokeratology might be more effective than 0.01% atropine ophthalmic solution in preventing myopia progression.
