Tear Film Alterations in Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis

Diagnostics
Background: Type 2 diabetes mellitus (T2DM) is increasingly recognized as affecting not only the retina but also the ocular surface. Chronic hyperglycemia can disrupt meibomian gland function, reduce tear secretion, and impair corneal sensitivity ...

The Relationship Between Tear Ferning Patterns and Non-invasive Tear Break-up Time in Normal Asian Population

Journal of Optometry, 2016
Purpose: To investigate the relationship between tear ferning patterns (TFP) and non-invasive tear break-up time (NIBUT) in normal Asian subjects. Methods: One hundred and forty-five adults with no ocular surface disorders were recruited.

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots

Advanced Robotics Research, EarlyView.
Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

Advanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

The comparison between invasive tear break up time and non-invasive tear break up time

, 2020
The Invasive Tear Break Up Time (TBUT) and Non-invasive Tear Break Up Time (NIBUT) is compared. Invasive TBUT was measured after the instillation of fluorescein on the tarsal conjunctiva and assessed with Slit Lamp Biomicroscopy (SLB), whereas the NIBUT ...

Tear film stability in children: Age and sex associations explored through non-invasive tear break-up time

Contact Lens and Anterior Eye
The stability of the tear film is crucial for maintaining good ocular health. Its assessment provides valuable insights into paediatric eye conditions. This study investigates the stability of the tear film in children and its association with predictive factors such as age and sex, for a better understanding of tear film dynamics in a paediatric ...
