方法：对42例84眼青少年假性近视患者随机分为视觉训练组和观察对照组，统计两组训练4wk后的视力、平均屈光度及两组训练前和训练后1，2，4wk后的5m时正相对调节量情况，并进行相关性分析。

结果：训练4wk后两组视力比较差异有统计学意义(P<0.05)，两组平均屈光度比较差异无统计学意义(P>0.05)； 训练1，2，4wk后的5m正相对调节量两组比较有统计学意义(P<0.05)，视觉训练组训练前与训练4wk后的5m时正相对调节差异显著(P<0.01)。

结论：视觉训练对青少年假性近视患者正相对调节影响显著。

METHODS: A total of 42 cases(84 eyes)were randomly divided into the visual training group and the control group. Visual acuity, average refraction of two groups 4wk after the training were measured, as well as positive relative accommodation(5m)were checked before the training and repeated 1, 2, 4wk after the training. Correlation analysis were given.

RESULTS: There was statistically significant difference in visual acuity 4wk after the training between the two groups(P<0.05). There was no significant difference statistically in average refraction 4wk after the training between the two groups(P>0.05). There was statistically significant difference in positive relative accommodation(5m)1, 2, 4wk after the training between the two groups(P<0.05). There was statistically significant difference in positive relative accommodation(5m)between the before and 4wk after the training in the visual training group(P<0.01).

CONCLUSION: Visual training has significant effect on the positive relative accommodation on adolescent pseudomyopia.
