Effect of Head-Mounted Virtual Reality Display on the Visual Function of Adult Myopia / 医学研究杂志

ABSTRACT

Objective To evaluate the effect of head-mounted virtual reality display on the visual function of adult myopia.Methods Thirty-four myopia patients were divided into two groups by random number table method:test group(n=18)and control group(n=16).After routine eye examination of the subjects,the naked vision,corrected vision,dynamic stereopsis,near stereopsis,contrast sensitivity,assemble value,disperse value,positive relative accommodation(PRA),negative relative accommodation(NRA),flexibility of accommodation,and amplitude of accommodation(AMP)before the test,after the test 1 time and after the test 10 times;the visual fatigue questionnaire score and the visual work ability answer score were performed before the test and after the test 10 times.Results There was significantly statistically significant of naked eye vision in test group after the test 10 times compared with the pre-test and the control group(P were 0.040,0.011);There was significantly statistically significant in assemble value of the test group after the test 10 times compared with the pre-test and the control group(P were 0.036,0.010);there were significantly statistically signifi-cant in the NRA and adjustment flexibility of the test group compared with the pre-test and the control after after the test 10 times(P were＜0.0001,＜0.0001,0.008,0.017);there were not statistical differences in corrected visual acuity,contrast sensitivity,spread value,dynamic stereopsis,near stereopsis,PRA,AMP,visual fatigue questionnaire scores and visual work ability were not statistically significant in comparison between the control group and the test group on the corresponding time points(P＞0.05).Conclusion This is helpful to improve some of the visual function parameters of myopia patients appropriate using of head-mounted virtual reality technology training such as naked vision,NRA,insufficient collection,and flexibility of adjustment.
