Infection of the glands of the eyelids.

Clinical features

Different types of stye are recognised:
  • external (hordeolum externum): infection (usually staphylococcal) of the glands of Zeis (sebum producing) or glands of Moll (sweat glands).
  • internal (hordeolum internum): infection of the Meibomian glands. May leave a residual chalazion (Meibomian cyst)
  • management includes hot compresses and analgesia. CKS only recommend topical antibiotics if there is an associated conjunctivitis
