Fig. 5From: Progress in tear microdesiccate analysis by combining various transmitted-light microscope techniquesRepresentative image of a normal tear microdesiccate as observed by transmitted-light microscopy with phase 2 illumination. Both tear microdesiccate production and the lens system of the microscope were those described in the legend to Fig. 3. Both the outer border of zone I and its close contact with a well-defined transition band are two main features of tear microdesiccates derived from Ph2 illumination. Fern-like crystalloids of zones II and III are also seenBack to article page
