CALAZION AND HORDEOLUM
, A. Definition
Hordeolum is an infection of one or more glands in the eyelids. When the
meibomian glands are affected it is known as an internal hordeolum.
Hordelum externa or commonly called "stye" is an infection of the glands of
Zeis or Moll. External hordeolum is often mistaken for a chalazion.5,6
Chalazion is a chronic, focal and sterile inflammation of the eyelids caused
by obstruction of the meibomian glands. Chalazion is also often referred to as
chronic sterile lipogranuloma. Deep chalazion is caused by inflammation of
the tarsal meibomian glands and superficial chalazion is caused by
inflammation of the glands of Zeis. Kalazia is the plural form of chalazion.
Chalazion is a benign and self-limiting condition although it can develop into
chronic complications. Recurrent chalazion needs further examination to
exclude the possibility of malignancy.5,7
B. Epidemiology
Hordeolum is a condition that often occurs and often patients do not go to
health services to check themselves. There is no direct correlation between
race, sex, or gender with regard to the prevalence of hordeolum. Adults may
be more susceptible due to increased sebum viscosity. Patients with conditions
such as blepharitis, seborrheic dermatitis, rosacea, diabetes, and
hypercholesterolemia are also at increased risk of developing hordeolum.6
Chalazion is a common condition, although the exact number of
occurrences either in the US or worldwide is not documented. Chalazion
