Abstract

Purpose: In order to aggregate effect of the improvement of binocular vision function by vision therapy, total mean effect size, mean effect size by dependent variables, and effect size by characteristics of the subjects and characteristics of treatment were analyzed by meta-analysis. Methods: We analyzed data from 14 Korean National primary studies, which reported effects of vision therapy programs, using meta-analysis. Results: The effect size of total mean was 1.207, which showed high effect. The mean effect size according to the subcategory of the binocular dysfunctions was the highest for vergence dysfunctions group (2.989), followed by accommodative dysfunctions group (0.868) and group with both vergence dysfunctions and accommodative dysfunctions (0.692). The effect size according to the characteristics of the subjects was the highest in the vision therapy conducted in the binocular dysfunctions group (2.509) that had no other dysfunctions. The mean effect size according to the number of programs was the highest (2.310) for 7 times a week. Vision therapy for improving the binocular functions was the most effective (2.019) in 8 weeks later from vision therapy start. Conclusions: It can prove that the therapy for the improvement of binocular vision function is effective through that each result of the vision therapy effect is converted to mean effect size, and being objectifying the mean effect size.

목적: Vision therapy 프로그램이 양안시기능 개선에 주는 효과를 통계적으로 종합하기 위하여 전체평균 효과크기, 종속변수별 평균 효과크기 그리고 대상특성과 처치특성에 따른 효과크기를 메타분석 기법을 이용하여 분석하고자 하였다. 방법: 자료의 분석을 위해 vision therapy 프로그램을 적용하고 그 효과를 분석한 국내 선행연구 14편을 선정하여 메타분석하였다. 결과: 전체평균 효과크기는 1.207로 높은 수준의 효과크기를 나타내었다. 양안시이상 유형별 하위영역의 평균 효과크기는 버전스 이상 그룹(2.989)이 가장 높았으며, 조절기능이상 그룹(0.868), 조절기능과 버전스 모두 이상이 있는 그룹(0.692) 순이었다. 대상특성에 따른 효과크기는 중복장애가 없는 양안시이상 그룹(2.509)을 대상으로 실시한 vision therapy가 가장 컸으며, 주당횟수별 평균 효과크기는 주당 7회의 처치 때 2.310으로 가장 큰 효과크기를 나타내었다. 그리고 처치기간에 따른 효과크기는 8주에서 2.019로 양안시기능 개선을 위한 vision therapy가 가장 효과적이었다. 결론: Vision therapy 효과에 대한 각각의 연구결과를 평균 효과크기로 변환하고 이를 객관화하는 방법을 통해 양안시기능 개선을 위한 치료가 효과적임을 증명할 수 있었다.
