305. Periocular dermatitis- How to perform diagnostics? What are your differentials?
Periocular dermatitis can occur for a multitude of reasons. The first step is to figure out if the eye itself is involved or not. Once we know the eye is healthy, it is time to figure out why the SKIN AROUND the eye is losing hair, crusty, itchy, etc.
It is important to return to the basic diagnostics. Cytology can be sampled with tape (if the lesion is dry) or swab (if the lesion is wet) to not risk damaging the eye. A trichogram can be used instead of a skin scrape to also protect the eye from a scalpel blade!
Anything that can cause folliculitis to other areas of the skin can impact the periocular dermatitis. Allergies, mites, dermatophytosis, pyoderma, yeast dermatitis, autoimmune diseases and neoplasia can cause lesions. Dive into the details on this week's episode of The Derm Vet podcast!
