title: Human tear cholesterol levels.
abstract: Using a cul-de-sac sampling method, tear cholesterol concentrations were measured for a population of subjects varying widely in age and relative body weight. Under unregulated conditions tear and plasma cholesterol levels failed to correlate significantly; however, when both diet and sampling times were strictly regulated, a number of well defined correlations did emerge amongst age, relative body weight, tear and plasma cholesterol levels. No significant response differences were found between the sexes in either the unregulated or the regulated formats however.
