Abstract

The slit lamp examination is a basic ophthalmologic examination method that allows the eye tissue to be examined through an optical section by cutting each tissue of the eye with a slit light beam. By using a light bulb with a vertical filament as a light source and reducing a circular light beam to a square, the width and length of the circular light beam can be arbitrarily adjusted, and the image can be enlarged up to about 40 times. Actually, isolation of the layer or entiny in the anterior ocular segment to be viewed is the key to slit lamp biomicroscopy. The techniques of biomicroscopic examination by slit lamp includediffuse illumination, diffuse focal illumination, indirect illumination, sclerotic scatter (indirect lateral illumination), retro-illumination, and specular reflection.
