Correlation of tear clearance rate and fluorophotometric assessment of tear turnover.
BACKGROUND The study sought to determine dynamic changes and theoretical bases of a clinical diagnostic test, the tear clearance rate. METHODS Thirty four healthy subjects ranging in age from 22 to 84 years underwent examination of tear clearance rate, the Schirmer test with anaesthesia, as well as fluorophotometric measurement of tear turnover, tear volume, and tear flow. By applying 0.5% fl...
متن کاملTurnover rate of tear-film lipid layer determined by fluorophotometry
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 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 کاملAssessment of tear film dynamics: quantification approach.
The dynamics of the tear film are reviewed with specific reference to the biophysical aspects: distribution, turnover and elimination through evaporation, drainage, and absorption. The review concentrates on quantitative assessments and is confined to aspects of the dynamics that can be fully and directly measured. The techniques of fluorophotometry, fluorescein clearance, lacrimal scintigraphy...
متن کاملAssessment of Tear Film Optical Quality Dynamics.
PURPOSE To investigate tear film optical quality dynamics by analyzing the postblink temporal changes of objective scatter index (OSI). METHODS A total of 109 myopic subjects without symptoms of dry eye and 32 myopic subjects diagnosed with dry eye disease were recruited in this cross-sectional study. The right eye for each subject was analyzed. Serial measurements of OSI were performed for 2...
