Nasolacrimal Lavage as a Treatment for Ocular Surface Toxic Soup Syndrome

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...

Saline Lavage for Sampling of the Canine Nasal Immune Microenvironment

Saline nasal lavage can be used to sample the canine nasal immune microenvironment. Because the approach is relatively non-invasive and does not disrupt the nasal tissues, it can be performed serially. Cells and proteins collected from the nasal lavage technique can be processed for various laboratory analyses.
