Fluorometry of the Anterior Segment

  • Chapter

Abstract

The anterior segment includes four transparent tissues and fluids—tear film, cornea, aqueous humor, and lens—that can be directly illuminated and observed by optical systems distant from the eye. It forms a system well adapted to the measurement of fluorescence in a noninvasive manner. The principal use of fluorometry has been to measure the concentrations of fluorescent tracers in these four media and how they change with time. By treating each tissue or fluid as a separate compartment (Fig. 15.1) the concentration changes can be mathematically analyzed to provide estimates of the permeability of cellular barriers, diffusion rates in solid tissues, and the rates of flow of the tears and aqueous humor.1
