Influence of Age and Sex on Flow of Tears

Concentration of Fluorescein in Tear Fluid after Instillation as Eye-Drops

“…3c, d) must be ascribed to diminished tear production at higher ages, which would result in less dilution and drainage of instilled drugs. This explanation is in agreement with our finding that in the screening of volunteers lower Schirmer test values occurred in the older age group, as has also been reported in the literature [Henderson and Prough, 1950]. The finding of a larger area under the curve in older individuals may indicate the possi bility, or even the risk, of greater drug resorption than is the case in younger individuals.…”

Impact of Cigarette Smoking on Tear Function and Correlation between Conjunctival Goblet Cells and Tear MUC5AC Concentration in Office Workers

“…Furthermore, the average age in men was significantly higher than that in women. Our data and those of previous reports373839 suggested that aging may cause a decline in tear secretion. In contrast, no significant difference in mean age was found between current smokers and non-smokers.…”

“…However, Schirmer test value was significantly decreased in subjects aged over 50 years, as compared to those younger than 30 years. Likewise, in previous investigations, the secreted tear volume decreased significantly with increasing age3738. Aging induces histopathological changes in the lacrimal gland, and Obata et al .…”

Tear secretion dysfunction among women workers engaged in light-on tests in the TFT-LCD industry

“…Another study indicated that the amount of tear secretion decreased with age [14]. In our study, however, age did not appear to be a significant predictor of tear secretion dysfunction.…”
