1 hordeolum pathogens: staphylococcus especlally staphylococcus aureus Clinical classification v internal hordeolum: meibomian gland infection Y external hordeolum(sty): Moll gland or Zeis gland infection

5 1. hordeolum  pathogens :staphylococcus especially staphylococcus aureus  Clinical classification: internal hordeolum ：Meibomian gland infection external hordeolum (sty)： Moll gland or Zeis gland infection

【 clinical manifestation】 Early findings N redness, swelling, pain N Preauricular lymph node enlargement Later findings N abscess external hordeolum: diabrosis through the skin surface internal hordeolum diabrosis into the conjunctival sac N Eyelid cellulitis
