视觉训练对近视青少年调节异常的疗效研究

Research of Curative Effect of Vision Therapy on Improving Accommodative Parameters of Myopic Adolescent

摘要: 目的：探讨视觉功能训练对存在调节参数异常和视疲劳症状学龄期青少年近视患者的治疗效果。方法：回顾性系列病例研究。选取黑龙江省医院南岗院区眼科门诊就诊的存在调节参数异常和视疲劳症状学龄期青少年近视患者60例，年龄6~18岁，平均(12.1 ± 2.8)岁。排除眼部疾病后进行屈光检查和双眼调节参数检测。根据调节功能异常种类，进行9周的视觉功能训练。对训练前后进行调节参数检查，结果采用配对t检验进行统计分析。结果：通过视觉功能训练，训练前后的调节幅度(t = −27.911，P < O.01)、正相对调节(t = 25.531，P < 0.01)、负相对调节(t = −9.801，P < 0.01)、调节灵活度(t = −30.099，P < O.01)均有显著改善，差异具有统计学意义。调节反应无明显变化，差异无统计学意义。结论：通过针对性的视觉功能训练可以改善调节功能，其中调节幅度、正相对调节、负相对调节和调节灵活度都有明显的提高，视疲劳症状明显改善。

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.
