Intraocular Scattering, Blinking Rate, and Tear Film Osmolarity After Exposure to Environmental Stress. [PDF]
Transl Vis Sci Technol, 2021 Purpose: Dry environments, such as those in offices or aircraft cabins, can potentially generate ocular discomfort and alter the tear film. We compare light scatter, blinking rate, and tear osmolarity in young and older subjects after exposure to low ...

A Model for Tear Film Thinning With Osmolarity and Fluorescein [PDF]
Investigative Opthalmology & Visual Science, 2014 We developed a mathematical model predicting dynamic changes in fluorescent intensity during tear film thinning in either dilute or quenching regimes and we model concomitant changes in tear film osmolarity.We solved a mathematical model for the thickness, osmolarity, fluorescein concentration, and fluorescent intensity as a function of time, assuming ...

Electronics-Free Visual Monitoring of Dry Eye Disease-Related Tear Biomarkers Using Smart Scleral Lenses. [PDF]
Adv Sci (Weinh)An electronics‐free smart scleral lens passively monitors dry eye disease‐related tear biomarkers through colorimetric sensing of chloride, pH, and ocular surface temperature. Smartphone‐assisted image analysis enables quantitative interpretation, providing a simple, non‐invasive strategy for ocular health monitoring without integrated electronics ...

Lacrimal and meibomian gland evaluation in dry eye disease: A mini-review
Indian Journal of Ophthalmology, 2023 Lacrimal and meibomian glands contribute to the aqueous and lipid components of tear film, respectively. Their evaluation remains central to diagnosing and managing dry eye disease (DED).

Clinical parameters obtained during tear film examination in domestic rabbits
BMC Veterinary Research, 2022 Background One of the contributing factors to ocular surface health is a stable precorneal tear film. Considering the increasing interest in rabbits as pets and the limited literature available on domestic rabbit tearing, the aim of this study was to ...

Programmable Budding and Fission of Janus Polymersomes for Tunable Cargo Release
Angewandte Chemie, EarlyView.A thermodynamic framework establishes the conditions for the formation of kinetically stable Janus polymersomes using a solvent‐assisted strategy. Osmotic stress subsequently drives their membrane remodeling from reversible budding to controlled fission.

Computed tear film and osmolarity dynamics on an eye-shaped domain [PDF]
Mathematical Medicine and Biology, 2015 The concentration of ions, or osmolarity, in the tear film is a key variable in understanding dry eye symptoms and disease. In this manuscript, we derive a mathematical model that couples osmolarity (treated as a single solute) and fluid dynamics within the tear film on a 2D eye-shaped domain.
