AIM:To investigate the changes of the positive relative accommodation in adolescent pseudomyopia with visual training.

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.
