    A larger optical coherence tomography (OCT) reference database improves glaucoma detection accuracy compared to a standard commercial database.

  • 2

    The study found significant discrepancies in glaucoma classification between a smaller and larger database, particularly in glaucomatous eyes.

  • 3

    Increased database size enhances sensitivity for detecting glaucomatous eyes while maintaining similar specificity for healthy eyes.

  • 4

    Discrepancies in classification are attributed to statistical variability rather than differences in patient populations.

  • 5

    Clinicians should view OCT outputs as statistical constructs influenced by the reference population, emphasizing the need for refined databases.
