  • Abstract
  • Look Inside

A new method for quantitative evaluation ofcataractous lens opacities was investigated. The lens opacities were recorded with retro-illumi-nation photography by the use of a Zeiss photo-slit lamp biomicroscope modified to eliminate the reflection from the corneal surface. The den-sity distribution of lens opacities was digitally demonstrated with a multi-color isodensitograph, or density contour map. The opacity area was measured in comparison with the total area of the dilated pupil.
