#1
Wing Li, Thao N Yeh, Tiana Leung, Tiffany Yuen, Mariel Lerma, Meng C Lin
Purpose: There has been interest in determining whether lid wiper epitheliopathy (LWE) plays a key role in causing ocular discomfort. Conflicting reports have made it difficult to discern whether LWE is more prevalent in certain populations, what characteristics are associated with its severity, and what its role is in symptomology. This cross-sectional study on a large and diverse population attempts to answer these questions. Methods: Subjects were asked to complete questionnaires related to dry eye and to ocular discomfort...

One drawback of traditional forms of medical ocular dosage is drug dilution by tear; moreover, drugs are rapidly drained away from pre-corneal cavity by tear flow and lacrimo-nasal drainage. Prolonging contact time with different strategies and mucoadhesive vehicles will help to continuously deliver drugs to the eyes. For this study, we prepared and evaluated the effects of a nanostructure lipid carrier (NLC) on propranolol hydrochloride as a hydrophilic drug model for rabbit corneal permeation. Propranolol hydrochloride NLC was prepared using cold homogenization...

INTRODUCTION: Complex mechanisms underlie dry eye (DE) symptom provocation. In particular, corneal hypersensitivity may provoke symptoms in short tear break-up time (BUT) DE characterized by tear film instability. We hypothesized that improved tear film stability may alleviate corneal sensitivity in patients with short tear BUT DE. Therefore, we investigated the effect of topical diquafosol tetrasodium (DQS) on corneal sensitivity in unstable tear film DE. METHODS: This prospective, randomized study included 27 subjects (age: 39...

Optimal vision requires an ocular surface with a stable tear film whose many critical tasks include providing >70% of the eye's refractive power. However for millions, tear film instability produces uncomfortable sight-impairing dry eye. Despite the multitude of etiologies for dry eye, a universal hallmark is hyperosmolarity of the tear film. Presently, knowledge of how the ocular surface responds to hyperosmolarity remains incomplete with little understood about the role of ion channels. This bioelectric analysis focused on conjunctival goblet cells whose release of tear-stabilizing mucin is a key adaptive response to dry eye...

From device application point of view, extreme mechanical strength of graphene is highly desirable. However, unavoidable polycrystalline nature of graphene films produced by chemical vapor deposition (CVD) leads to significant fluctuations in mechanical properties. Although the effects of atomic defects or grain boundaries (GBs) on mechanical strength have been widely studied and some modifications have been applied to enhance the stiffness of graphene, the problems of fragility as well as significantly reduced breaking strength arise...

Background Dry eye disease is a common chronic condition that is characterized by ocular discomfort and visual disturbances that decrease quality of life. Many clinicians recommend the use of supplements of n-3 fatty acids (often called omega-3 fatty acids) to relieve symptoms. Methods In a multicenter, double-blind clinical trial, we randomly assigned patients with moderate-to-severe dry eye disease to receive a daily oral dose of 3000 mg of fish-derived n-3 eicosapentaenoic and docosahexaenoic acids (active supplement group) or an olive oil placebo (placebo group)...

Dry eye disease (DED) is one of the most common ophthalmological diseases with an increasing prevalence in recent years. Numerous general and ocular risk factors exist for the development of DED. The pathogenesis of DED is multifactorial and complex, characterized by a loss of homeostasis of the tear film, inflammatory mechanisms at the ocular surface, hyperosmolarity of tears and neurosensory abnormalities. DED is classified into the two sub-categories, aqueous deficient dry eye and evaporative dry eye. Apart from a detailed patient history, basic and complementary diagnostic tests are necessary to enable an individualized and efficient therapy...
