-1-2 days will localize to eyelid body
-drains through inner eyelid surface
-spontaneously absorbs in 2-8 weeks
What causes hordeolum
Infectious, painful localized swelling to the eyelid margin
What is a chalazion
Non-infectious obstruction of the meibomian gland causing irritation of lipid material in eyelid and soft tissue
What are some risk factors for chalazions
Meibomian gland disfunction
acne
rosacea
What side effect outside of eyelid swelling can a chalazion cause
indentation of the cornea causing blurred vision
What type of infection causes hordeolum
Pyogenic staph infection
Where are hordeolum found on the eye
external from obstruction/infection of eyelash follicle and adjacent gland (Zeis and moll glands)
What is the clinical presentation of an external hordeolum
1-2 days of tearing, photophobia, foreign body sensation
