Ectropion describes the “rolling out” of the lower eyelid, from its normal position in contact with the eye.
Ectropion is usually a result of age-related stretching of the lower eyelid, but can also follow a facial nerve palsy or stroke, or result from excessive tightening of the lower lid skin following eczema or a facial trauma. It typically results in a tear overflow and watering due to disturbance of normal tear drainage. This may result in inflammation and soreness of the lower lid and a tightening of the lower lid skin which can further increase the degree of ectropion.
Ectropion can usually be corrected by tightening of the lower lid; insertion of a skin graft may be required in cases of skin ‘shortage’ of the lower lid.
