Paralytic Ectropion

Paralytic ectropion is outward turning of the lower eyelid due to facial-nerve (CN VII) palsy, causing orbicularis weakness and lid eversion. Clinical: epiphora, lower-lid eversion, exposure keratopathy, and incomplete eye closure. Treatment: lubrication/night ointment/taping to protect the cornea; treat facial palsy; lateral tarsal strip/temporalis transfer for persistent paralytic ectropion.

Common Symptoms

Lower-lid eversion; epiphora; incomplete closure; exposure keratopathy; facial palsy

Causes and Pathogenesis

Facial-nerve palsy weakens orbicularis, allowing lower-lid eversion and exposure.

Treatment

Lubrication/taping; treat facial palsy; lateral tarsal strip/temporalis transfer if persistent

Preventive Measures

Protect cornea; treat facial palsy.
