Fig. 6

Representative image of a normal tear microdesiccate as observed by transmitted-light microscopy with phase 3 illumination. Both tear microdesiccate production and the lens system of the microscope were those described in the legend to Fig. 3. Zone I is not visible but the transition band is well-defined. In addition, optimum contrast of fern-like crystalloids is achieved so that the border between zones II and III can readily be identified
