Internal tarsus-orbicularis resection for senile spastic entropion.

This report describes the surgical correction of senile spastic entropion by internally resecting tarsus and orbicularis muscle. A triangle of tarsus is removed with the apex at the margin and the base at the inferior border and a similar amount of orbicularis muscle is resected. Each layer is approximated separately. The shortened tarsus improves the apposition of the lid aagainst the globe and the tightened orbicularis aids in maintaining this stability.
