A computerized video keratoscope (TMS-1) was used to determine the topographic findings of 6 eyes of 4 patients with keratoconus and they were compared with those of 18 normal eyes. The results show that in keratoconus the central corneal refractive power is greater, the difference between the refractive powers of the bilateral central corneas of a case is larger and the inferior cornea is steeper than the superior cornea. The above topographic findings are possibly the characteristics of the corneal topography of keratoconus.
使用电脑化视频角膜曲率计（TMS - 1）测定4例圆锥角膜患者6只眼的地形学结果，并与18只正常眼的结果进行比较。结果显示，圆锥角膜患者中央角膜屈光力更大，同一病例双侧中央角膜屈光力差值更大，且下角膜比上角膜更陡峭。上述地形学结果可能是圆锥角膜角膜地形图的特征。
