|
|
the most common cause of acquired ectropion?
|
involutional. lid laxity with age.
|
|
its rare that ectropion be congenital but if its due to blepharophimosis syndrome what is this?
|
the abnormal narrowness of the palpebral fissure in the horizontal direction caused by the lateral displacement of the medial canthi
|
|
its rare that ectropion be congenital but if its due to microphthalmos what is this?
|
developmental anomaly where the globe is abnormally small.
|
|
congenital ectropion may be associated with buphthalmos which is?
|
An enlarged globe resulting from increased IOP. seen with pts that have congenital glaucoma.
|
|
Congenital Ectropion may be associated with?
|
Down syndrome, Orbital cysts, or Buphthalmos
|
|
Involutional Ectropion. Laxity-related ectropion typically begins laterally,centrally or medially
|
medially
|
|
four words that are used to describe ectropion are
|
punctal, medial, lateral, and tarsal (complete)
|
|
name two ways that lower lid laxity can be tested
|
lid distraction test > 8mm and the snap test >1- 2 sec to return both indicate lid laxity.
|
|

|
show their teeth
|
|
If the ectropion is due to a paralytic problem what should be the first thing done?
|
wait for three months it should resolve on its own.
|
|
A cicatricial cause of ectropion could be due to?
|
chemical burn, surgery, eyelid laceration scar, or others
|
|
If conjunctiva is markedly keratinized what should be done first?
|
lubricating ointment should be used several days or weeks prior to ectropion repair

|
ocular irritation, FB sensation, tearing, red eye, potopobia, decreased vision (possible)
|
|
objective findings for entropion.
|
turned in eyelid, SPK, FB tracking, conj injection, corneal ulcer, decreased cornela sensation, corneal scaring
|
|
causes of entropion
|
involutional, acute spastic, or congenital, cicatricial
|
|
entropion caused by acute spastic entropion is caused by what?
|
the orbicularis oculi muscle overwhelms the oppositional action of the lower eyelid retractors.
|
|
you may have to ask the pt to ______in order to see acute spastic entropion.
|
blink
|
|
most pt's with acute spastic entropion will show a(n)_____ component as well.
|
involutional
|
|
acute spastic entropion is usually the result of?
|
ocular irritation, may be due to an infectious, inflammatory or traumatic processes.
|
|
Congenital entropion is very rare but may arise due to underlying developmental abnormalities such as
|
dysgenesis, paucity of tissue vertically in the posterior lamella of eye lid, or tarsal kink syndrome
|
|
causes of cicatricial entropion could be?
|
scaring of the palpebral conj usually the result of trauma, infection, chemical burn or stevens-johnsons syndrome, ocular cicatricial pemphigoid
|
|
what is ocular cicatricial pemphigoid (OCP) (a cicatricial cause of entropion
|
Rare inflammatory syndrome involving primarily the oral and ocular mucous membranes
|
|
entropion Must be distinguished from Epiblepharon which is?
|
A congenital condition in which the pretarsal orbicularis muscle and the skin covering the eyelid push the eyelashes vertically or inwards
|
|
three differential diagnoses of entropion
|
trichiasis (misdirection of lashes), distichiasis (lashes out of Miebomian galnd), trachoma (chlamydia)
|
|
Plan for entropion
|
Medical therapy- lubrication (may break cycle of spastic ent.). hygiene/ antibio and steroid to treat bleph. which coud be causing the spastics. Botox-weakens pretarsal orbicularis.
