Slit-Lamp Biomicroscopy

aqueousA focused light source and microscope are used simultaneously to image ocular structures. By varying the width, angle, alignment and intensity of illumination, it is possible to detect the location of corneal and lenticular opacities and irregularities of the lids or membranes, identify scars or foreign bodies, and note changes in pigmentation or corneal and conjunctival thicknesses.
