Prevention of ectropion will depend on the underlying cause. If ectropion is caused by allergies, medications to relieve allergy symptoms may prevent ectropion. In some cases, ectropion cannot be prevented, such as ectropion due to aging or trauma.
If not treated, an ectropion results in drying of the eye with irritation and permanent redness. Other long-term effects will depend on the cause of the ectropion.
Ectropion is not contagious and poses no risk to others.
