Abstract

To define the distribution of normal corneal topographic patterns of Korean adults and compare them with previously published western data, computerized corneal topography was performed on the randomly selected eye of 232 normal subjects using TMS-1(Computed Anatomy). Recruited subjects were 116 females and 118 males. Mean age of the subjects was 50.5 yr. (range 17 to 86 yr.). The color-coded videokeratographs were classified by a masked observer according to the Bogan et al's classification such as round, oval, symmetric bow tie, asymmetric bow tie, and irregular. The results revealed 16 eyes (6.9%) had round. 31 (13.4%) oval, 42 (18.1%) symmetric bow tie, 99 (42.7%) asymmetric bow tie, and 44 (19.0%) irregular pattern. There was no statistically significant difference in the distribution of topographic pattern between male and female and among the age groups. Our results of topographic patterns show the tendency of more irregular and less round topographic pattern in Korean adults, as compared to that of western adults.
