목적: 융합버전스 훈련이 부분조절내사시 수술 후 폭주과다를 보이는 피검사자의 시력교정에 미치는 효과를 알아보고자 하였다. 방법: Block string, tranaglyphs, aperture ruler 및 저자들이 제작한 융합훈련 프로그램을 이용하여 4주 동안(주 6일, 매회 1시간씩) 강제훈련을 실시하였다. 결과: 내사시는 원거리 6△, 근거리 8△ 감소되었고, 시력은 양안 모두 0.8에서 1.0으로 향상되었다. 결론: 부분조절내사시 수술 후 폭주과다를 보이는 경우 융합버전스 훈련은 양안 시기능개선과 시력교정 에 유용한 방법이다.
Purpose: This study was examined whether fusional vergence therapy is an effective method for improvements of binocular functions and visual acuity on subject who has convergence excess after partially accommodative esotropia surgery. Methods: Fusional vergence therapy was performed to subject by force for 4 weeks (6 days a week, for 1 hour once) using block string, tranaglyphs, aperture ruler, and training program of fusional vergence that is made by authors. Results: Esotropia was decreased 6△ at far and 8△ at near, visual acuity was improved in 1.0 from 0.8 in both OD and OS. Conclusions: Fusional vergence therapy is an useful method for improvements of binocular functions and visual correction in case of convergence excess after partially accommodative esotropia surgery.
