What is Proximal Illumination used for?

A silhouetted image is created which helps determine the general size, shape and location of an opaque object obscured by overlying soft tissue, such as embedded foreign bodies.

2

How is Proximal Illumination preformed?

Illumination: Moderately narrow silt of light is directed to strike adjacent to the area of interest.
Microscope: low to moderate magnification depending on the size of the area of interest. You will be viewing adjacent to the light beam.

3

How is Sclerotic Scatter preformed?

Microscope: Low magnification or the naked eye. View the pathology at the right angle to the light source.
