Dry eye disease (DED) is an ocular condition characterized by altered tear film homeostasis, resulting in symptoms like tear film instability, hyperosmolarity, inflammation, and neurosensory abnormalities. It affects visual acuity and quality of life and is influenced by age, gender, and environmental factors. The first line of treatment consists o...

Parkinson's disease is one of the most prevalent neurological disorders affecting millions of people worldwide. There is a growing demand for novel and natural substances as complementary therapies. Essential oils and their various compounds are highly investigated natural plant-based products as potential treatment options for common human disease...

Background: Traditional and evidence-based medicines, as seen depicted throughout human history, reportedly first begin with the application of medicinal plants, animal products, or inorganic minerals as a basic framework towards effectively engineering the prototypes generally aligned to pharmaceuticals and medical nutrition. The growing global tr...

Diabetes mellitus affects carbohydrate homeostasis but also influences fat and protein metabolism. Due to ophthalmic complications, it is a leading cause of blindness worldwide. The molecular pathology reveals that nuclear factor kappa B (NFκB) has a central role in the progression of diabetic retinopathy, sharing this signaling pathway with anothe...

An imbalance of homeostasis in the retina leads to neuron loss and this eventually results in a deterioration of vision. If the stress threshold is exceeded, different protective/survival mechanisms are activated. Numerous key molecular actors contribute to prevalent metabolically induced retinal diseases—the three major challenges are age-related...

Glucocorticosteroids are key anti-inflammatory agents in the treatment of ophthalmic and systemic inflammatory diseases. However, prolonged use may result in an increase in intraocular pressure followed by a potentially vision-threatening ocular complication as glaucomatous neuropathy ultimately leading to blindness. Steroid therapy can increase in...

Purpose The aim of our research was to investigate the reliability and clinical applicability of a modern tear film imaging tool by comparing the inter- and intragrader difference. The further goal was to compare the non-invasive tear break-up time (NIBUT) measured with the LacryDiag® device with traditional tear film break-up time (TBUT). Methods...
