  • Look Inside

A new device For photographing the catarac-tous lens opacities with retro-illumination has been investigated.

The Photo-Slit Lamp (Carl Zeiss) was modi-fied with newly deviced adaptor to eliminate the reflection from the corneal surface. The sub-ject's eye was illuminated with horizontally po-larized beam. The lens opacities were photogra-phed on the same optical axis to the illumination beam through a polaroid which axis of polarization was vertical. Additionally an orange filter was used to increase the image contrast.

The results are satisfactory with high resolu-tion and good contrast.
