Influence of Aging on the Polar and Neutral Lipid Profiles in Human Meibomian Gland Secretions

Open access
Sullivan, Benjamin D.·2006·Archives of Ophthalmology

Abstract

OBJECTIVE: To determine whether aging is associated with significant alterations in the polar and neutral lipid profiles in human meibomian gland secretions. METHODS: Meibomian gland secretions were collected from both eyes of younger and older men and women. Samples were processed for high-performance liquid chromatography or mass spectrometry and for the analysis of associated spectra of fragment ions. Subjects also underwent slitlamp evaluations of the eyelid. RESULTS: Aging is associated with numerous significant alterations in the lipid profiles of human meibomian gland secretions. Analysis of polar and neutral lipid patterns identified ions that were significantly different in secretions of younger vs older men and women, as well as ions that varied significantly only between men and women. Correlation coefficients within, but not between, groups were high. Aging was accompanied by increased opacity of meibomian gland secretions and by eyelid and eyelid margin changes. CONCLUSION: Aging is associated with significant sex-related alterations in the polar and neutral lipid profiles of human meibomian gland secretions. CLINICAL RELEVANCE: The observed changes may contribute to the age-related increase in the prevalence of dry eye syndromes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
