    The study analyzed tear metabolomic differences between active blepharokeratoconjunctivitis (BKC) and herpes simplex keratitis (HSK).

  • 2

    Tear samples were collected from 24 HSK patients, 19 BKC patients, and 15 healthy controls for metabolomic profiling using LC-MS/MS.

  • 3

    HSK exhibited 21 altered metabolites, while BKC showed 19 altered metabolites compared to healthy controls.

  • 4

    A combined panel of metabolites, including 4-dodecylbenzenesulfonic acid, carnosol, and sorbitol, demonstrated good specificity and sensitivity for differentiating BKC and HSK.

  • 5

    The study provides insights into the distinct metabolic profiles associated with HSK and BKC, aiding in their differential diagnosis.
