Behavior of sphingomyelin and ceramide in a tear film lipid layer model.
Tear film lipid layer is a complex lipid mixture forming the outermost interface between eye and environment. Its key characteristics, such as surface tension and structural stability, are governed by the presence of polar lipids. The origin of these lipids and exact composition of the mixture are still elusive. We focus on two minor polar lipid components of the tear film lipid later: sphingom...

AIM This study was performed to independently assess the turnover rates of aqueous and lipid layers of the tear film. METHODS Two fluorescent dyes, fluorescein sodium and 5-dodecanoylaminofluorescein (DAF), which is a free-fatty-acid conjugate of fluorescein, were applied to the right eye of 12 healthy volunteers. Fluorescent intensity of the precorneal tear film was measured at the central c...
متن کاملA compositional based model for the tear film lipid layer.
BACKGROUND The tear film lipid layer is formed from lipids secreted by meibomian glands of the eyelid. After initial analyses of these lipids we concluded that an understanding of the function of the various classes of lipids in a normal lipid layer could only be understood after detailed investigations of both polar and nonpolar lipids of the meibomian gland. METHODS Meibomian gland secretio...
متن کاملLearning features on tear film lipid layer classification
Dry eye is a prevalent disease which leads to irritation of the ocular surface, and is associated with symptoms of discomfort and dryness. The Guillon tear film classification system is one of the most common procedures to diagnose this disease. Previous research has demonstrated that this classification can be automatized by means of image processing and machine learning techniques. However, a...
