Ectropion is an abnormal distortion of the eyelids in which they roll outwards so that there is exposure of the underlying conjunctiva. It only affects the lower eyelid. and the entropion may affect the whole length of a lid or just part of it. Sometimes ectropion and entropion (turning in of the lid) are present at the same time. Tears collect in the pocket that this creates, and if the tear duct is out of position tears may overflow from the eye.

Diagnosis can be made by visual examination of the eyelids

If the ectropion is minor, simply an undesirable cosmetic affect and not causing any clinical signs no treatment is necessary.
