사진촬영으로 측정한 카파각

Abstract

Purpose: The kappa angles of human eye were measured by photographs. The relationship between the dominant eye and far refractivity is studied. Methods: 112 adults participated in this study. The mean age was years. The kappa angles were measured by the deviation of the flash image in the photographs of eye. the dominant eye and the far refractivity were analyzed. Results: The distributions of kappa angles were 78.6% (176 eyes) in the positive angle, 15.2% (34 eyes) in the negative angle, and 6.2% (14 eyes) in the . The kappa angles were for the dominant eye, for the non-dominant eye, for the hypermetropia, for the emmetropia, and for the myopia. The biggest kappa angles was odserved in the hypermetropia and the angles was getting smaller in the emmetropia, and the myopia. Conclusions: The kappa angle of the dominant eye was smaller than non-dominant eye. The kappa angle was smaller as the far refractivity is lower. The kappa angle can be directly measured by the photographic method.
