  • *All essential findings were required for the diagnosis of Fuchs’ uveitis syndrome, and were strengthened by the presence of associated findings in revised diagnosis criteria.

  • †All essential findings and at least two associated findings must be present in the La Hey criteria.

  • ‡Essential findings in the criteria.

  • §Associated findings in the criteria.

  • SUN, Standardisation of Uveitis Nomenclature.
