Entropion refers to the inward turning of the eyelid's free edge, causing contact between the eye and the eyelashes.
The causes can be diverse:
- Spasmodic entropion (for example, following a surgical intervention)
- Involutive entropion: occurring due to tissue changes (progressive laxity) related to aging.
- Cicatricial entropion: following burns or certain diseases (such as trachoma, etc.).
- Congenital entropion: present at birth.
The treatment for entropion is surgical and involves the correct repositioning of the eyelid tissues.
