Tell-tale tears: Decoding the clues

28 Feb 2026
OSA
Discussion workshop

The TFOS DEWS III report encourages personalised dry eye management recommendations tailored to individual patient needs. This interactive session will explore how identifying key tear film biomarkers, specifically IgE, MMP-9, and lymphotoxin-α (LTA) can transform our approach to diagnosing and managing ocular surface disease.

  • Attendees will understand the role of tear film biomarkers in ocular surface health.
  • Attendees will be able to interpret clinical relevance of tear film biomarkers in diagnosing and managing allergic eye disease, dry eye, and inflammatory conditions.
