Purpose : We studied the relationship of dominant eye and fixing eye in heterophoria and heterotropia. Methods : Fifty-one subjects(Male: 21, Female; 30) were measured between seven to sixty three years, evaluated to alternate cover test after AR/K(Canon RK-Fl, Japan) measw·ed. Ocular dominance was determined using hole in-the-card test before measured in subjective refraction. Prism bar was determined using objective deviating tropia angle after refraction. Results : Intermitant heterotropia patients were the most 26 patients(Sl%) in binocular anomalies, equaled to dominant eyes and fixing eyes were 28 patients(55%), non equaled to dominant eyes and fixing eyes were 23 patients(45%). Alternated dominant eyes were searched in esotropia and exotropia each to one patient, esophoria patints were nothing. Dominant eyes had greater degree of myopia than nondominant eyes but show no significant difference between eyes(p=0.95), fixing eyes had lesser degree of myopia than nondfixing eyes but show no significant difference between eyes(p=0.88). Conclusions : The analysis showed that using a combination of dominant and fixing eye test because small deviating eyes would be likely to different from dominant eye to fixing eye, alternated fixing eyes.
