A hordeolum is the result of an acute bacterial infection of one or more eyelidglands.
Staphylococcus aureusis a common cause ofhordeolum. External hordeolum involves infection of the glands of Zeis or Moll. Internal hordeolum arises from infection of the meibomian glands. Hordeolum is often associated with diabetes, gastrointestinal disorders, or acne.
Hordeolum presents aspainfulnodules with a central core of pus. External hordeolumappears on the margin of the eyelid where the sweat glands are located (Fig. 2.17).Internal horde-olum of a sebaceous gland is usuallyonly revealed by everting the eyelidandusually accompanied by a more severe reaction such as conjunctivitis or che-mosis of the bulbar conjunctiva. Pseudoptosis and swelling of the preauricu-lar lymph nodes may also occur.
Chalazion (tender to palpation) and inflammation ofthe lacrimal glands (rarer and more painful).
Antibiotic ointments and application of dry heat (red heat lamp)will rapidly heal the lesion.
After eruption and drainage of the pus, thesymptoms will rapidly disappear. The prognosis is good. An underlying inter-nal disorder should be excluded in cases in which the disorder frequently recurs.
