Abstract

Purpose: This research was designed to figure out if there are changes based on types of vergence fixation disparity curve after optical correction and vision training to for people with steep slope of forced vergence fixation disparity curve and symptoms. Methods: For 30 subjects out of 91 subjects, who have steep slopes of fixation disparity curve examined with Wesson Fixation Disparity Card and symptoms about steep slope of fixation disparity curve, proper vision training was offered for 5 weeks. Results: After Vision training for 30 people with the symptoms of type I, II, III, IV for 5 weeks, slope of fixation disparity curve was significantly changed (p=0.013), and the results of binocular vision test and subjective symptoms were also significantly improved. Conclusions: Vision training can not only affect the change of fixation disparity curve, but also relieve the symptoms. Fixation disparity curve has lots of visual function information of the subject and can be suggested as a guideline for prescribing.

목적: 본 연구에서는 강제vergence 주시시차곡선에서 기울기가 가파르고 증상이 있는 사람들을 대상으로 광학적 교정과 시기능훈련이 곡선 type별로 변화가 있는지를 알아보고자 하였다. 방법: 91명의 대상자에 대해 wesson fixation disparity card로 강제vergence 주시시차곡선을 그려 그 중 유형별로 기울기가 가파르고 증상이 있는 대상자 30명을 선택하여 그에 맞는 프로그램에 따라 5주 동안 시기능훈련을 실시하였다. 결과: type I, II, III, IV 중 증상을 호소하는 30명에 대해 5주 동안 실시한 시기능훈련 전과 후에 대한 기울기의 변화에는 유의한 변화(p=0.013)가 있었으며, 양안시검사값 및 자각적인 증상 또한 현저히 호전되었다. 결론: 시기능훈련은 주시시차곡선의 변화에 영향을 주며 증상 또한 완화하는데 효과가 있었다. 주시시차 곡선은 대상자에 대한 많은 정보를 담고 있으며, 또한 처방의 가이드라인으로 제시될 수 있다.
