Anterior High-Resolution Optical Coherence Tomography in the Diagnosis and Therapeutic Monitoring of Ocular Surface Squamous Neoplasia06:15

Anterior High-Resolution Optical Coherence Tomography in the Diagnosis and Therapeutic Monitoring of Ocular Surface Squamous Neoplasia

1.8K
Anterior segment high-resolution optical coherence tomography (HR-OCT) is a promising non-invasive modality for the diagnosis and therapeutic evaluation of ocular surface squamous neoplasia (OSSN). Here, the system setup, scanning technique, and representative diagnostic results are...

Induction of Ocular Surface Inflammation and Collection of Involved Tissues

2.8K
Ocular surface inflammation harms the ocular surface tissues and compromises vital functions of the eye. The present protocol describes a method to induce ocular inflammation and collect compromised tissues in a mouse model of Meibomian gland dysfunction (MGD).

A Method to Induce Ocular Surface Inflammation in a Murine Model

648
This video demonstrates a method to induce ocular surface inflammation and meibomian gland dysfunction in a murine model. Stimulation of the mouse's immune system using an immunogen and later restimulation with the same immunogen promotes ocular surface inflammation, which causes plugging of meibomian gland secretion through neutrophil-produced aggNETs and leads to dry eye...

Nasolacrimal Lavage as a Treatment for Ocular Surface Toxic Soup Syndrome

1.1K
OSTSS leads to pooled inflammatory mediators in the tear film, causing symptoms like epiphora and discomfort. Here, we present a case where therapeutic nasolacrimal lavage every 2 months resolved epiphora and itchiness, suggesting its efficacy as a therapeutic intervention for OSTSS. Additionally, we report subjective improvements in symptoms in 3 additional...
