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 کاملTear film stability: a review.
Tear film stability can be assessed via a number of tools designed for clinical as well as research purposes. These techniques can give us insights into the tear film, and allow assessment of conditions that can lead to dry eye symptoms, and in severe cases, to significant ocular surface damage and deterioration of vision. Understanding what drives tear film instability and its assessment is al...
متن کاملTear exchange and contact lenses: a review.
Tear exchange beneath a contact lens facilitates ongoing fluid replenishment between the ocular surface and the lens. This exchange is considerably lower during the wear of soft lenses compared with rigid lenses. As a result, the accumulation of tear film debris and metabolic by-products between the cornea and a soft contact lens increases, potentially leading to complications. Lens design inno...
متن کاملClinical Tests Diagnostic for Rotator Cuff Tear
This clinical outcomes study aimed to determine the commonly used shoulder tests predictive for rotator cuff tear (RCT). The study was carried out in 2 parts involving 400 patients who attended the senior author’s practice (n = 100/group). Part I compared patients with isolated RCTs and a “No-RCT” group. Part II compared RCT patients (some with isolated RCTs, others with RCTs and combined patho...
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...
