Pre-Lens Tear Meniscus Height, Lipid Layer Pattern and Non-Invasive Break-Up Time Short-Term Changes with a Water Gradient Silicone Hydrogel Contact Lens

open access: yesLife, 2022
To evaluate pre-lens tear film volume, stability and lipid interferometry patterns with a silicone hydrogel water content contact lens, a novel, noninvasive, ocular-surface-analyzer technology was used.

Dynamics of tear film deposition and draining

open access: yes, 2005
This paper investigates the deposition of the tear film on the cornea of the human eye. The tear film is laid down by the motion of the upper eyelid and then subsequently flows and thins.

Evaporation-driven instability of the precorneal tear film [PDF]

open access: yes, 2018
Tear-film instability is widely believed to be a signature of eye health. When an interblink is prolonged, randomly distributed ruptures occur in the tear film. "Black spots" and/or "black streaks" appear in 15 to 40 s for normal individuals.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Effect of ocular demodicosis on the stability of the tear film and the tear break up time

open access: yesScientific Reports, 2021
AbstractThe aim of the study was to analyze the correlation between the presence of Demodex mites in the hair follicles of patients' eyelashes and the stability and break up time of the tear film assessed with the Non-Invasive Tear Break Up Times (NIBUT) method. 319 patients were included in the study (195 women, 124 men).

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Changes in corneal and conjunctival sensitivity, tear film stability, and tear secretion after strabismus surgery.

open access: yes, 2006
PURPOSE: Some patients complain of a foreign body sensation, a burning sensation, or dryness after strabismus surgery. We prospectively investigated the changes in corneal and conjunctival sensitivity, tear film stability, and tear secretion after ...

Tolerance to Systemic Isotretinoin Therapy in Two Patients Using Highly Wettable Contact Lenses

open access: yesCase Reports in Ophthalmological Medicine, 2014
Purpose. Numerous ocular side effects have been reported with the use of systemic isotretinoin therapy. Herein, we presented two contact lens user patients who did not have contact lens intolerance during systemic isotretinoin therapy. Methods.

A Prospective Analytical Study to Study the Characteristics of Tear Film in Patients of Rheumatoid Arthritis before and after Immunosuppressant Therapy [PDF]

open access: yesJournal of Medical Academics
Background: Rheumatoid arthritis (RA), a systemic autoimmune disorder, frequently presents with ocular manifestations, notably dry eye disease (DED), due to immune-mediated damage to the lacrimal and meibomian glands.
