Structural Differences in Meibum From Teenagers Without and With Dry Eye and Allogeneic Hematologic Stem Cell Transplantations.

Although dry eye occurs mostly in adults, dry eye may be induced in teens receiving allogeneic hematologic stem cell transplantations (AHSCT). Changes in meibum composition and structure has been associated with dry eye. The structure of meibum from teens with dye eye or teens with dry eye and AHSCT has not been studied, so in this study, we compared the structure of meibum from teens receiving AHSCT that had a dry eye with meibum from teens without AHSCT and without dry eye symptoms.
