[Entropion: therapeutic indications]

The severity of entropion depends on trichiasis which is perpetuated by orbicularis spasm, creating a vicious cycle. The therapeutic approaches are based on the aetiopathogenesis. Congenital entropion is essentially treated by infraciliary cutaneomuscular resection. The various components of involutional (senile) entropion, horizontal and vertical retraction, orbicularis dyskinesia, are treated respectively by tissue reduction, reinforcement of retractore and myoplasties. In cicatricial entropion, chondro-mucosal or fibromuscular graft is the technique of choice for correcting insufficiency of the tarsoconjunctival plane or its curvature. It is also the best solution for the correction of trichiasis or distichiasis.
