Cholesterol in human tear fluid

Tear Cholesterol Levels in Blepharitis

“…The cholesterol levels estimated in our study are similar to those given in other studies [2,3]. Like all lipids in biological fluids, cholesterol has to be transported by aand p-lipoproteins; thus, due to the very low protein content of tears, the tear cholesterol concentrations have to be lower than 200 mg/dl [4], It is likely that the cholesterol amounts reported are derived from the oily layer of the tear film.…”

“…Cholesterol has been reported to be present in the tear fluid in concentrations of about 8-200 mg/dl [2,3], No significant cor relation was found between the tear and plasma cholesterol concentration or with those factors as age or relative weight [4], Blepharitis, in its many clinical forms, is a common ocular condition and bacterial co lonization of the eyelids is believed to be the cause of altered meibomian-gland secretion [5]. In order to search out an alteration of the tear lipids in chronic blepharitis, we con ducted a study that was based upon the determination of the tear cholesterol levels in 17 patients with chronic blepharitis and in 17 healthy controls.…”

Asymptomatic Meibomian Gland Dysfunction and Cardiovascular Disease Risk Factors in a Middle-Aged Population in Taiwan - A Cross-sectional Analysis

“…Therefore, it is crucial to discuss the association between MGD and dyslipidemia. Although some studies in the past have suggested that meibomian gland is capable of synthesizing lipid de novo 22, 23 , more recent studies, although differing in various degrees, have found correlations between meibomian lipids and serum lipid profile levels (Table 5). In 2010, Dao et al .…”

The effect of albumin and cholesterol on the biotribological behavior of hydrogels for contact lenses

“…Values reported in the literature for cholesterol concentration in the tear fluid fall in a wide range (1.8 -244 mg/L) [29,[35][36][37], depending on factors such as the type of tears, method of sampling and analysis techniques.…”
