Disorders of the Eyelids and Lacrimal Apparatus Flashcards
Hordeolum vs Chalazion
Hordeolum - usually caused by infection and remains painful and localizes to eyelid margin
Chalazion - caused by non-infectious meibomian gland, becomes small nontender nodule in eyelid corner
Both are sudden onset localized swellings of eyelid
both initially cause eyelid hyperemia, edema, swelling and pain
Hordeolum and Chalazion
Treatment of Hordeolum and Chalazion
Primarily hot compresses
Both conditions improve spontaneously
via ophtho consult - corticosteroid injection (chalazion), oral abx (hordeola)
Chalazion sx
initially diffuse swollen eye
1-2 days localizes to body of eyelid
small non-tender nodule or lump develops
spontaneously absorbed over 2-8 wks
depending on size and location can cause slightly blurred vision
Hordeolum (stye) sx
acute localized swelling of eyelid that may be external or internal
usually staph
result from obstruction and infection of eyelash follicle and adjacent glands
external - 2-4 days lesion ruptures and discharges material thereby relieving pain, resolving lesion
internal - rupture is rare, recurrence is common
inflammation of the eyelid margins, acute or chronic
Blepharitis
Two types of blepharitis
acute ulcerative
acute non-ulcerative
itching and burning of eyelid margins with redness and edema
conjunctival irritation with lacrimation, photosensitivity, FB sensation
Blepharitis s/sx
treatment of acute ulcerative and non-ulcerative blepharitis
ulcerative - topical abx or systemic antiviral
non-ulcerative - topical corticosteroids
Chronic blepharitis treatment
tear supplements
warm compresses
oral abx - maybe
usually bacterial infection (staph) of eyelid margin at origins of eyelashes; last follicles and meibomian glands
can have viral source (HSV, VZV)
acute blepharitis
acute non-ulcerative blepharitis is usually caused by
allergic reaction involving the same area (intense itching, rubbing, rash)
entropion vs ectropion
entropion is inversion of an eyelid
ectropion is eversion of lower eyelid
Entropion is caused by
age-related tissue relaxation, post infectious changes, post traumatic changes or blepharospasm
Entropion treatment
surgery
