Fig. 9

Representative image of a normal tear microdesiccate as observed by transmitted-light microscopy with Ph1⁺/Ph2 illumination. Both tear microdesiccate production and the lens system of the microscope were those described in the legend to Fig. 3. Again, both a roughly cylindrical continuous zone I, a complex transition band and the structured body of the tear desiccate displaying clearly defined major and minor crystalloids could be jointly appreciated. Filaments can be also seen as integral parts of zone I
