This psychophysiological study is the first to examine the relationship between emotional tears and emotional piloerection (i.e., goosebumps). Although both phenomena have been related to peak states of being moved, details about their temporal occurrence and the associated levels of physiological arousal have remained unknown. In our study, we used emotionally powerful film scenes that were self-selected by participants. Our findings show that even within peak moments of emotional arousal, a gradation of intensity is possible...

Lack of current techniques for the early monitoring of bleb leaks and other post-traumatic or post-surgical ocular injury has posed an unmet clinical need for the development of new techniques. Present evaluation techniques use either subjective or non-quantitative approaches. At present, there are no FDA approved ocular devices that can directly measure ascorbic acid (AA) concentration levels for both tear film (TF) and aqueous humor (AH) at point-of-care (POC) level. Toward this aim, we present a novel point-of-care (POC) quantitative assay, called the Ocular Biosensor device, which can be used to evaluate the integrity of the anterior surface of the eye by measuring the concentration of AA in TF and AH...

The human precorneal tear film (PCTF) is a special body fluid, since it is a complex mixture of proteins, lipids small bioactive molecules and their concentrations and relative distribution represent not only the metabolic state of the ocular surface but also the systemic and local homeostasis of the outer eye and the human body. This suggests that biochemical analysis of the PCTF composition may provide a non-invasive tool for diagnosis and monitoring of disease progression or treatment efficacy in human medicine...

BACKGROUND AND OBJECTIVES: The analysis of the interference patterns on the tear film lipid layer is a useful clinical test to diagnose dry eye syndrome. This task can be automated with a high degree of accuracy by means of the use of tear film maps. However, the time required by the existing applications to generate them prevents a wider acceptance of this method by medical experts. Multithreading has been previously successfully employed by the authors to accelerate the tear film map definition on multicore single-node machines...

PURPOSE: To compare clinical tear film break-up time measurements obtained non-invasively, with those measured following minimal and conventional volumes of fluorescein instillation. METHODS: Forty-one subjects (20 male, 21 female, mean±SD age 34±11years), with or without dry eye, participated in a prospective cross-over study. Tear film break-up time was measured by the Tearscope Plus™ with fine grid insert. Measurements were made in triplicate, with no fluorescein instillation (NIBUT), then following application of a minimal volume of 1μl fluorescein from the Dry Eye Test™ (mTBUT), and finally with 15-30μl of fluid instilled via a conventional fluorescein strip (TBUT)...

In humans, the lacrimal gland (LG) is the primary contributor to the aqueous layer of the tear film. Production of tears in insufficient quantity or of inadequate quality may lead to aqueous-deficiency dry eye (ADDE). Currently there is no cure for ADDE. The development of strategies to reliably isolate LG stem/progenitor cells from the LG tissue brings great promise for the design of cell replacement therapies for patients with ADDE. We analyzed the therapeutic potential of epithelial progenitor cells (EPCPs) isolated from adult wild-type mouse LGs by transplanting them into the LGs of TSP -1(-/-) mice, which represent a novel mouse model for ADDE...

INTRODUCTION: Laser in situ keratomelieusis (LASIK) is one of the commonest refractive procedures performed nowadays. The dry eye problem is nearly universal in all patients after LASIK and it can be so annoying that the post-operative patient satisfaction is sometimes precluded. Conventional treatment includes the use of artificial tears. Alternative methods such as punctal plugs and botulinum toxin injection can be used for the management of post-LASIK dry eye. The aim of this study is to compare botulinum toxin injection in the orbicularis muscle to lacrimal punctal plugs for the control of post-LASIK dry eye manifestations...

Dry eye disease is one of the most common diagnoses in ophthalmology. A variety of subjective and objective test methods with imprecise limits and highly different sensitivities and specificities complicate the diagnosis. Especially mild to moderate pathological findings can be misdiagnosed. In recent years, new options have opened, through the development of new, clinical practicable diagnostic equipment, for example, for the analysis of tear film osmolarity or matrix metalloproteinases (MMP-9). The value of tear film osmolarity and determination of MMP-9 levels in the diagnosis of dry eye and its subtypes will be discussed and evaluated objectively, on the basis of published study results...

Tear film alterations in dry eye disease (DED) include reduced tear volume and an increase in inflammatory cytokines. Instability and reduced tear production initiate a vicious cycle where hyperosmolarity, ocular inflammation, and apoptosis may induce damage of the ocular surface including keratitis. Topical cyclosporine (CsA) has been used for the treatment of moderate-to-severe DED; however, previous studies failed to demonstrate its benefits by the European Agency standards. A new formulation of CsA 0.1% has been recently approved in the EU to treat severe keratitis in DED patients...

Meibomian gland dysfunction (MGD) is a common and chronic disorder that has a significant adverse impact on patients' quality of life. It is a leading cause of evaporative dry eye disease (DED), as meibomian glands play an important role in providing lipids to the tear film, which helps to retard the evaporation of tears from the ocular surface. MGD is also often present in conjunction with primary aqueous-deficient DED. Obstructive MGD, the most commonly observed type of MGD, is the main ocus of this article...
