Assessment 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...
متن کاملObjective optical assessment of tear-film quality dynamics in normal and mildly symptomatic dry eyes.
PURPOSE To evaluate and compare the tear-film dynamics in normal eyes and in eyes with mild dry-eye symptoms using a new noninvasive optical method based on a double-pass instrument. SETTING Hospital Universitario Virgen de la Arrixaca, Murcia, Spain. DESIGN Evaluation of diagnostic test or technology. METHODS Dynamic recording of double-pass retinal images during unforced tear-film break...
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 Quality among Smokers Using Tear Ferning Patterns
Purpose. To investigate the effect of cigarette smoking on the ocular tear film. Methods. Thirty healthy young male cigarette smokers (20-38 years old) and 30 healthy age matched nonsmokers were enrolled in the study. McMonnies questionnaire, slit lamp, and PRT test were used to screen the subjects. Tear samples were collected from the right eyes and tear ferning patterns were observed and grad...
متن کاملTear film dynamics in floppy eyelid syndrome.
PURPOSE Floppy eyelid syndrome (FES) presents nonspecific ocular surface irritation. The hypothesis for the current study was that one contributing factor is the abnormality in tear film dynamics. METHODS Sixteen patients with FES were consecutively examined. Tear film dynamics were evaluated by kinetic tear interference images, infrared thermometry, water evaporation rate, tear break-up time...
