Discussing Dry Eye Diagnostics

Here, I discuss the available DED diagnostics, organized by traditional and modern (point-of-care) methods.

1

Dry eye disease (DED) affects productivity and quality of life, often leading to contact lens dropout and complications in eye surgeries.
2

Traditional diagnostic methods for DED include symptom questionnaires, vital dyes, tear break-up time, and Schirmer’s test.
3

DED is classified into aqueous-deficient and evaporative subtypes, with a mixed mechanism commonly observed in patients.
4

Modern diagnostic tools like MMP-9 testing and tear osmolarity provide objective measures that enhance DED diagnosis and management.
5

Combining traditional and modern diagnostic approaches improves accuracy in diagnosing DED, leading to better patient outcomes.
