ectropion ec·tro·pi·on (ěk-trō'pē-ŏn', -ən)
A rolling outward of the margin of a body part, especially an eyelid.
ectropion may affect the upper lid, but it occurs far more frequently in the lower.
Cicatricial contraction after severe burns may lead to marked deformities of the eyelids (ectropion), mouth, and nose.
The operation may also be applied to ectropion of the lower lid.
The degree of ectropion, whether it is partial, affecting merely the lid margin; or complete, affecting the whole lid.
Canthorrhaphy is also desirable in some cases, especially when the ectropion affects the outer end of the lid.
(i) Contraction of the puncta following marginal blepharitis, especially when associated with ectropion.
(ii) To help maintain the lid in position after ectropion operations.
