On the tear resistance of skin
Tear resistance is of vital importance in the various functions of skin, especially protection from predatorial attack. Here, we mechanistically quantify the extreme tear resistance of skin and identify the underlying structural features, which lead to its sophisticated failure mechanisms. We explain why it is virtually impossible to propagate a tear in rabbit skin, chosen as a model material f...
متن کاملNoninvasive assessment of tear stability with the tear stability analysis system in tear dysfunction patients.
PURPOSE To evaluate tear film stability in patients with tear dysfunction and an asymptomatic control group by using the novel, noninvasive Tear Stability Analysis System (TSAS). METHODS In this prospective case-control study, 45 patients with dysfunctional tear syndrome (DTS) were stratified into three groups (1, 2, and 3/4) based on clinical severity, with higher scores indicating more seve...
متن کاملTear secretion and tear film function in insulin dependent diabetics.
BACKGROUND Diabetic patients often complain of dry eye symptoms, such as burning and/or foreign body sensation. The aim of the present study was to investigate whether diabetes mellitus is correlated with tear film dysfunction and/or tear hyposecretion. METHODS In 86 consecutive insulin dependent diabetics with retinopathy and 84 non-diabetic controls (age and sex matched) we performed fluoro...
متن کاملTear glucose in diabetics.
THE purpose of this investigation was to evaluate a method of screening suspected diabetics, suitable for those without hospital facilities. This has been made possible by the recent use of a specific enzyme, glucose-oxidase, which is so sensitive as to detect glucose in solution in concentrations as low as 5 mg./100 ml. A commercial preparation, Clinistix (Ames Co.), has been used to detect gl...
متن کاملTear proteomics in keratoconus
PURPOSE The purpose of this work was to identify potential tear-film based proteins expressed in keratoconus. METHODS Recruited subjects were normal gas permeable (GP) contact lens wearers, keratoconus subjects wearing GP contact lenses, and keratoconus subjects without contact lenses. Subjects wearing soft lenses or having previous ocular surgeries were excluded from participating. Approxima...
