Comparison of Schirmer's test and tear film breakup time test to detect tear film abnormalities in patients with pterygium.
OBJECTIVE To compare tear film breakup time test with Schirmer's test in patients with pterygium. METHODS The case-control study, involving 86 patients with unilateral primary pterygium aged between 30 and 70 years, was conducted at the Department of Ophthalmology, Karachi Medical and Dental College, Abbasi Shaheed Hospital, from May 2009 to December 2010. The eye with pterygium was taken as ...
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 کاملMathematical modelling of glob-driven tear film breakup.
Evaporation is a recognized contributor to tear film thinning and tear breakup (TBU). Recently, a different type of TBU is observed, where TBU happens under or around a thick area of lipid within a second after a blink. The thick lipid corresponds to a glob. Evaporation alone is too slow to offer a complete explanation of this breakup. It has been argued that the major reason of this rapid tear...
متن کاملAutomated Tear Film Surface Quality Breakup Time as a Novel Clinical Marker for Tear Hyperosmolarity in Dry Eye Disease.
PURPOSE To assess the diagnostic performance of a novel, automated, noninvasive measure of tear film stability derived from Placido disc videokeratography, the tear film surface quality breakup time (TFSQ-BUT), as a clinical marker for diagnosing dry eye disease (DED) relative to a standard of tear hyperosmolarity. METHODS This prospective, cross-sectional study involved 45 participants (28 D...
متن کاملtear film break-up time in bipolar disorder.
ocular dryness is a well-recognized adverse side effect of many topical and systemic medications. in psychiatry, patients who have consumed such drugs as lithium carbonate and sodium valproate frequently experience dry eye symptoms. the purpose of this study was to compare tear film stability between patients who use these drugs with those patients who are not on medication.after obtaining info...
