A stereo image obtained using a Technival Carl Zeiss Jena stereomicroscope, which shows part of the ocular vasculature in two diaphanized eyeballs.

The diaphanization technique is based on the principle that a tissue refracts the least amount of light and reaches its maximum transparency when it is surrounded and embedded in a substance whose refractive index equals the average refractive index of the tissue. If the blood vessels have previously been infused with a coloured resin, the ocular vasculature can be studied.
