A new method for observing normal and pathologic states of the human t
ear film using tandem scanning confocal microscopy is presented. The c
onfocal microscope is configured with a horizontal light path, a 10 x
dry objective, and an image-intensified camera for collecting images a
t a magnification of approximately 150x. The advantages of confocal mi
croscopy can be used to collect reflected images of the human tear fil
m with improved detail and resolution.
