Abstract

Distributions of angle kappa and of cycloplegic refraction and their association were studied. The subjects were 282 nonstrabismic Korean children, aged from 6 years to 11 years. who visited Ewha Women University Hospital from December 1990 to March 1991. The angle kappa was measured by major amblyoscope, and refraction was done under the cycloplegic state. The results were as follows: The frequency of angle kappa was positive. negative and 0 degree in decreasing order. The average values of refractive error and angle kappa were -1.03 +/- 2.20 degrees dipter and +1 34 +/- 1.33 degrees. The average values of angle kappa for hypermetropia, emmettopia and myopia were +2.52 +/- 0.81 degrees, +1.71 +/- 1.03 degrees and +0.90 +/- 1.37 degrees. And these values were significantly different from each other.
