ABSTRACT:
Fluorescence of the anterior chamber of an eye is determined by projecting a ribbon of light from the side of the eye through the anterior chamber in a direction generally perpendicular to the optic axis of the eye. The ribbon of light is obtained by imaging the face (20) of a fiber optic bundle (18) and directing that image into the anterior chamber by a mirror (30) mounted adjacent to a contact lens (40). The contact lens (40) includes a flexible membrane (14) backed by a fluid. The pressure of the fluid can be varied by a syringe (44) to vary the curvature of the contact lens membrane (14). The fluorescence can be detected either directly by a photodiode (68) or through a fiber optic bundle (34) by a photomultiplier (76).
