Eyelid dermatitis (ED) is a common and distressing skin condition that is difficult to diagnose due to similarity of its subtypes — allergic, irritant, and atopic ED. These may require different treatments. Misdiagnosis may lead to delayed and ineffective care. Reliable objective tests to tell them apart are lacking.
Tear fluid, collected in seconds using a small strip, is in direct contact with the inflamed eyelids and carries molecular signals reflecting the underlying disease. During my visit to Bispebjerg Hospital, Copenhagen, I will profile immune proteins called chemokines in the tear fluid of patients with different ED subtypes, using cutting-edge protein analysis technology. I will also develop a biosensor capable of identifying the ED subtype from a single tear sample at the clinic.
The expected results are the first molecular diagnostic tool for eyelid dermatitis subtyping, objective markers for monitoring treatment response, and a biosensor prototype for clinical use.
