Ectropion usually affects the lower eyelid, causing it to turn outwards. The supporting structure of the lower eyelid is similar to a hammock attached by two tendons to the bone on either side of the eye. This eyelid support becomes stretched due to ageing or from facial palsy (paralysis) , trauma or scarring As the inner part of the eyelid sags outwards and loses the moisture from the eye’s surface, it is exposed and becomes irritated. Also, the tears cannot flow into the tear duct. This can lead to discomfort and watering and can interfere with the adequate closure of the eyelids.

Treatment
Non-surgical treatments for ectropion can include using lubricating drops when the eye feels gritty and sore.
The long term treatment frequently requires surgery to turn the eyelid margin and eyelashes away from the eye. This is normally done with an injection to numb the eyelid, sometimes sedation is needed in more complex cases.
