Objective To evaluate the efficacy of visual perception training system based on cloud computing. Methods This was a clinical trials study. Eighty-eight of sixty cases of monocular or binocular amblyopia aged from 5 to 19 years old were collected from hospital data during January to May 2014, and were randomly divided into Group A (43 eyes of 30 cases)and Group B (45 eyes of 30 cases). Subjects in Group A received the near work, Group B were trained with visual perception training based on cloud computing. Both groups trained for 3 months. Occlusion therapy was used in the unilateral amblyopic patients. Visual acuity and contrast sensitivity were compared between the two groups. Data were analyzed using ANOVA and t-test, and compare of contrast sensitivity using Bonferroni. Results After one month′s training, visual acuity in amblyopic eyes were improved in both groups, but the improvement was larger in Group B (t=-2.405, P<0.05). After three months′ training, visual acuity and contrast sensitivity were both improved in two groups, but the improvement was more significant in Group B (t=-2.883, P<0.05). For the monocular amblyopic patients, the ″fellow eye″ in Group B also showed a significant improvement in contrast sensitivity at medium spatial frequency (t=-3.580, P<0.008 3), but there were no significant differences in Group A. Conclusion The visual perception training method based on cloud computing can effectively improve the visual function in amblyopic patients, and is expected to become a new way for treatment of amblyopia.
