Ectropion

Ectropion means that the eyelid margin has turned or everted outward and is no longer in contact with the eyeball. It affects the lower eyelid in the majority of cases.

The upper and lower eyelids protect the eye from the external environment. Any exposure of the eyeball from ectropion can cause eye problems.

The most common cause of ectropion is the sagging and laxity of the lower eyelid which is due to age, namely involutional or senile ectropion. Other causes include post traumatic or surgical scars, skin burns, facial or mechanical paralysis (tumor or other).

In front of an ectropion the protection of the eyeball decreases and this depends on the degree of the ectropion.

When the eye is exposed to ambient air without the full protection of the lower eyelid, the globe becomes irritated, red with chronic tearing. In very advanced cases there may be an ulceration, infection or corneal abscess, a scar or chronic corneal opacity.

The inner palpebral part of the exposed lower eyelid may change in structure and appearance, becoming keratinized like the skin. This can interfere with the tear point and the tear drainage system.

The treatment of palpebral ectropion is surgical. The classic surgical technique for repairing senile involutional ectropion is the lateral tarsal strip or the tarsal strip technique associated with canthoplasty and canthopéxieie reformed the corner or the external angle of the 2 eyelids.

This technique consists of repositioning the eyelid by reattaching it to the orbital periosteum while repairing sagging and palpebral laxity (It is like a belt of pants that is wide and its length is greater than a person's waist. , we cut the excess is the refix on the loop)

Other surgical techniques are used to treat ectropion and especially the cause, such as skin grafting and other means of eyelid repair
