Abstract

Purpose: The repeatability of a new Red-Blue phoria chart test (Red-Blue phoria chart; RBP) was appreciated. Methods: Distance (5 m) and near (40 cm) heterophoria was measured in 38 visually normal subjects. Phoria tests using RBP, Howell phoria card (HP), and MIM card (MIM) were done and the repeatability of each phoria test was compared with one another. Results: The mean of horizontal deviations was that RBP was $-0.602{\pm}0.727{\Delta}$, HP was $-0.865{\pm}1.051{\Delta}$, and MIM was $-1.501{\pm}1.346{\Delta}$, at distance, and that RBP was $-2.566{\pm}2.352{\Delta}$, HP was $-2.804{\pm}2.411{\Delta}$, MIM was $-3.838{\pm}2.603{\Delta}$, at near. The repeatability was RBP>MIM>HP in distance tests and MIM>RBP>HP in near tests. Conclusions:RBP test is identified as a reliable phoria test having high repeatability.

목적: 새로운 적청사위시표(Red-Blue phoria chart; RBP) 검사의 신뢰성을 평가하였다. 방법: 38명을 대상으로 원거리(5m), 근거리(40cm) 사위량을 측정하였다. RBP 시표 사위검사, 하웰시표 사위검사(HP), 그리고 Muscle Imbalance Measure (MIM) 시표 사위검사를 실시하고 검사에 대한 신뢰도를 서로 비교하였다. 결과: 수평 사위도는 원거리 RBP $-0.6{\pm}0.727{\Delta}$, HP $-0.87{\pm}1.051{\Delta}$, MIM $-1.50{\pm}1.346{\Delta}$, 근거리 RBP $-2.57{\pm}2.352{\Delta}$, HP $-2.80{\pm}2.411{\Delta}$, MIM $-3.84{\pm}2.603{\Delta}$로 측정되었다. 검사 신뢰도는 원거리의 경우 RBP>MIM>HP 순이었고, 근거리의 경우 MIM>RBP>HP 순으로 나타났다. 결론: RBP 검사법은 신뢰도가 높은 사위검사법으로 판명되었다.
