noninvasive, practical, and easy-to-use tool.
PURPOSE: This study aimed to assess the tear film in smokers, those with a high body mass index (BMI), and
healthy subjects using the EASYTEAR view+.
METHODS: Thirty men with a high BMI (>25 kg/m2
; 24.4 ± 6.4 years), 30 smokers (25.1 ± 6.1 years), and 30
healthy subjects (22.2 ± 3.5 years) were recruited. Each subject completed the Ocular Surface Disease Index, followed
by the assessment of noninvasive tear breakup time, tear meniscus height (TMH), and lipid layer patterns (LLPs).
RESULTS: Significant differences were found in the median TMH scores between smokers and healthy subjects
(P = .03) and between subjects with a high BMI and the healthy ones (P = .04). The median LLP score was significantly
(P < .001) higher in normal subjects (4.0 [1.0]) than in smokers (2.4 [1.0]) and subjects with high BMI (2.0 [1.3]). For
subjects with a high BMI, the noninvasive tear breakup time score was strongly correlated (Spearman rank correlation coefficient; r) with TMH (r = 0.552, P = .002) and LLP (r = 0.555, P = .001). The LLP showed that grade B (lipid layer thickness, 30 to 50 nm; more compact) was common in subjects with a high BMI, grade C (50 to 80 nm, gray waves) was predominant in smokers, and grade D (~80 nm, dense white-blue layer) represented the majority of normal eye subjects.
CONCLUSIONS: Smokers and individuals with a high BMI showed significantly lower lipid layer grades and tear meniscus height scores compared with the control group. The assessment of tear film parameters using the EASYTEAR
view+ supports the findings of previous studies that implicate smoking and high BMI as risk factors for dry eye.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]LarmesMots-clés : solution électrolytique Résumé : SIGNIFICANCE: The current study is the first report to describe the improvement of ferning patterns of human tears using electrolyte solutions. The results can help in the production of new artificial tears to improve the quality of tears.
PURPOSE: This study aimed to investigate the effect of the addition of different volumes of various electrolyte solutions on ferning patterns of human tears.
METHODS: Tear samples (20 μL) were collected from the right eye of 13 subjects (5 men and 5 women) aged 19 to 36 years (27.1 ± 5.1 years) with normal eyes. Then, 1 μL of each tear sample was dried on a microscopic glass slide, and obtained ferns were observed using light microscopy and graded using the 5-point tear ferning (TF) grading scale. Homogenous mixtures of each tear sample (0.5 μL) and different volumes (0.5 to 5 μL) of each electrolyte were prepared. A sample (1 μL) of each mixture was dried, and the ferns obtained were graded and compared with those of the corresponding tears collected from subjects before the addition of electrolyte solutions.
RESULTS: After the addition of electrolyte solutions, the TF grades of tears collected from healthy humans were generally improved. Significant (Wilcoxon test) improvements have been seen in the TF grades of the tear samples after the addition of a solution of potassium chloride ( P = .03), calcium chloride ( P = .01), magnesium chloride hexahydrate ( P = .002), and sodium dihydrogen phosphate ( P = .002). No significant improvements in the TF grades were seen after the addition of sodium chloride solution ( P = .33).
CONCLUSIONS: Ferning grades of human tears improved with most of the electrolytes usedPermalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
