Should eye care professionals adopt more precise diagnostic tests for early detection of Sjögren disease?
Researchers found the Schirmer test has lower diagnostic sensitivity for Sjögren dry eye disease compared to ocular staining scores. This data may refine how the condition is diagnosed as new disease-modifying treatments approach availability.
Why it matters
Current medical criteria weight the Schirmer test and ocular staining scores equally, but this study suggests the latter is more accurate. Refining these diagnostic tools is crucial for identifying patients who may benefit from emerging disease-modifying therapies.
A latent class analysis of 3,514 participants from the SICCA cohort evaluated the accuracy of four diagnostic tests. The results indicate that the ocular staining score achieved 91.4% sensitivity and 83.9% specificity, significantly outperforming the Schirmer test's 47.5% sensitivity.
The details
The ocular staining score uses specialized dyes to highlight damage on the eye's surface, providing a clear visual indicator of ocular health. In contrast, the Schirmer test measures tear volume using paper strips, which may miss underlying pathological patterns in Sjögren patients. Researchers are now analyzing tear proteins via phage immunoprecipitation sequencing to identify specific endotypes, which could help predict how individual patients respond to different therapeutic pathways.

2027: Potential availability of new disease-modifying drugs for Sjögren disease.
Health Landscape
This study challenges the diagnostic weighting established by the 2016 ACR/EULAR criteria for Sjögren disease. By identifying more reliable indicators, researchers are aiming to better classify patient endotypes ahead of the expected 2027 arrival of new disease-modifying treatments.
If you are undergoing evaluation for Sjögren dry eye disease, it may be helpful to ask your doctor about the relative reliability of the ocular staining score versus the Schirmer test. Understanding which tests are most effective can help ensure you receive an accurate diagnosis as new treatment options emerge.
The takeaway
Reliable testing is becoming increasingly vital as the field moves toward targeted, disease-modifying therapies. Speak with a rheumatologist or ophthalmologist to discuss the most accurate diagnostic methods available for your specific symptoms.
What happens next
New disease-modifying therapies for Sjögren disease are projected to become available in 2027.
