Ectropion
Ectropion, defined as an outward rolling of the eyelid, is relatively infrequent in dogs compared with entropion[2].
This condition is commonly observed as a genetic condition in certain breeds such as bassetts and bloodhounds[3].
Ectropion also occurs following excessive blepharoplasty repair of entropion, and in association with severe facial scarring due to burns[4] and dermatopathies such as squamous cell carcinoma[5], facial pyoderma, demodicosis[6] and chronic third-eyelid eversion (cherry eye)[7].
Clinical affected dogs have visibly everted eyelid(s), and common complications include conjunctivitis, corneal ulcers and keratoconjunctivitis sicca.
Diagnosis is based on ophthalmic examination of the eye.
Treatment usually requires wedge-resection of the eyelid to tighten the eyelid commissures[8].
