cicatricial ectropion

Also found in: Dictionary.

cic·a·tri·cial ec·tro·pi·on

ectropion of the eyelids after burns, lacerations, or skin infection and caused by shortening or contraction of the anterior and/or middle lamellae.


Inward turning of the eyelid. It results in the eyelashes rubbing the cornea (as in trichiasis) and this usually causes discomfort. The most common cause of entropion that occurs in old people (called involutional entropion) and only affects the lower eyelid is due to a combination of atrophy and weakening of the tarsus, loss of tone of the subcutaneous tissues and loss of elasticity of the skin. Other causes are scarring (e.g. trachoma, Stevens-Johnson syndrome), burns of the palpebral conjunctiva (called cicatricial entropion) which may affect either the upper or the lower eyelid, or spasm of the orbicularis muscle often resulting from an ocular inflammation or lid infection (called acute spastic entropion) which may subside spontaneously once the original cause has been removed. Temporary relief of entropion may be provided by the taping of the lower eyelid to the cheek but the treatment is usually surgical. See ectropion; therapeutic soft contact lens; orthopaedic spectacles; tarsus; trichiasis.

congenital e . A rare congenital inversion of the eyelid usually associated with tarsal hypoplasia or microphthalmia. It may be confused with epiblepharon. If treatment is needed it is surgical, although many cases resolve spontaneously with time.


eversion or turning outward, as of the margin of an eyelid.

cicatricial ectropion
caused by contraction of scar tissue following injury or surgery to the eyelid.
congenital ectropion
most commonly seen in some breeds of dogs, such as St. Bernard, Bloodhound and spaniels where it may be considered normal. Called also heritable ectropion.

may occur in some dogs intermittently for unknown reasons.

Cicatricial ectropion occurs when relative shortening of the anterior lamellar leads to eversion of the eyelid away from the globe.
Findings on physical examination included left lower eyelid vertical shortening, chemosis, keratitis, dacryocystitis, and cicatricial ectropion secondary to atrophy of the rectus abdominis flap with skin tethering (figure 1, A).
This is called cicatricial ectropion and can happen after wounds or burns.
