This study reveals varied prevalence of dry eye disease drivers, identifying four distinct patient clusters. This supports a precision medicine approach for personalized dry eye disease management.
Area of Science:
- Ophthalmology
- Dry Eye Disease Research
- Ocular Surface Disease
Background:
- Dry eye disease (DED) diagnosis traditionally uses limited metrics, failing to address its complex nature.
- The TFOS DEWS III framework emphasizes understanding DED heterogeneity.
- A multimodal approach is needed to accurately classify DED subtypes.
Purpose of the Study:
- Implement a novel, multimodal DED evaluation strategy.
- Determine the prevalence of pathophysiological DED drivers.
- Identify clinically relevant DED phenotypic clusters.
Main Methods:
- Prospective, cross-sectional study of 615 participants (aged 20-45) meeting TFOS DEWS II criteria.
- Comprehensive ocular surface tests assessed nine drivers across tear film, eyelid, and ocular surface domains.
- Cluster analysis identified DED phenotypes based on driver prevalence.
Main Results:
- Prevalence of DED drivers varied: mucin/glycocalyx deficiency (88%), aqueous deficiency (61%), bulbar hyperaemia (48%), meibomian gland dysfunction (43%), reduced corneal sensitivity (37%), incomplete lid closure (24%).
- Cluster analysis revealed a robust four-cluster model, partitioning patients into distinct subgroups.
- Clusters showed progressive driver involvement and severity, from early signs to severe multi-driver disease.
Conclusions:
- Confirms heterogeneous prevalence of DED drivers in a clinical population.
- Identifies four distinct DED phenotypic clusters, supporting a move towards precision medicine.
- Enables phenotyping and targeted therapy selection for personalized DED management.
