Research of Curative Effect of Vision Therapy on Improving Accommodative Parameters of Myopic Adolescent
Abstract: Objective: To investigate the vision therapy effect on improving accommodative parameters of myopic adolescent with dysfunction and symptoms of asthenopia. Methods: In a retrospective series of case study, 60 myopic adolescents aged 6 to 18 years (average 12.1 ± 2.8 years) were recruited from the Department of Ophthalmology of Heilongjiang Province Hospital. All patients had routine eye examinations to exclude eye disease. Personalized vision therapy was performed based on the results of accommodative parameters’ examination and refraction with a phoropter. The accommodative parameters were assessed after 9 weeks’ vision therapy. All data were statistically analyzed by a paired sample’s t test. Results: The accommodative amplitude (t = −27.911, P < O.01), positive relative accommodation (PRA, t = 25.531, P < 0.01), negative relative accommodation (NRA, t = −9.801, P < 0.01) and accommodative facility (t = −30.099, P < O.01) were significantly improved. There was no difference in accommodative response after therapy. Conclusion: The accommodative parameters’ accommodative amplitude, NRA, PRA and accommodative facility improved after personalized vision therapy, and the symptoms of asthenopia were relieved remarkably.
