[Involutional entropion and ectropion].
Entropion and ectropion are very common among old people. These malpositions concern mostly the lower lids. Involutional entropion and ectropion have some pathophysiologic mechanisms in common: lower lid horizontal laxity and lid retractor detachment. However, orbicularis muscle hypertrophy occurs only in entropion, and excess of posterior lamella has to be considered in ectropion. Clinical examination will guide surgical treatment. The authors present the main surgical procedures according to clinical findings. The goal is to prevent recurrence.
