Zone i of Tear Microdesiccates Is a Lipid-Containing Structure
(Lippincott Williams and Wilkins, 2017)
Copyright © 2016 Wolters Kluwer Health, Inc. All rights reserved. Purpose: Morphological features of tear microdesiccates on glass surfaces have been associated with tear fluid status. Tear-film lipids play a critical role ...
Stratification of Tear Components During Tear Microdesiccation on Vertical Glass Surfaces: A Novel Approach in Tear Fluid Assessment
(Wolters Kluwer Health, 2015)
Purpose:Tear desiccation on a horizontal glass surface followed by low-resolution light microscopy has been used as an expeditious diagnostic aid to evaluate patients suspected of dry eye. The presence of fern-like ...
Progress in tear microdesiccate analysis by combining various transmitted-light microscope techniques
(Sociedad de Biología de Chile, 2016)
Background: Tear desiccation on a glass surface followed by transmitted-light microscopy has served as diagnostic test for dry eye. Four distinctive morphological domains (zones I, II, III and transition band) have been ...
Protein dye-binding assay on cellulose membranes for tear protein quantification - Use of conventional Schirmer strips
Purpose: To develop a method to quantify tear protein concentration with the sensitivity to measure this variable in the restricted volumes of single human tear samples. Methods: Aliquots of tear fluid from healthy subjects ...

Microdesiccates produced from normal human tears display four distinctive morphological components
Desiccation of human tears on glass surfaces results in fern-like crystalloids. This phenomenon has been associated with tear normality (Tear Ferning Test, TFT) and is used as a diagnostic aid to evaluate patients with ...
Dynamics of tear fluid desiccation on a glass surface: a contribution to tear quality assessment
(BioMed Central, 2014)
Background: Fern-like crystalloids form when a microvolume of tear is allowed to dry out at ambient conditions on a glass surface. Presence of crystalloids in tear “microdesiccates” is used to evaluate patients with ...
