ABSTRACT

The pathophysiologic changes that lead to involutional entropion are Weakness of the lower lid retractors, Upward migration of preseptal orbicularis over pretarsal orbicularis and forward rotation of lower border of tarsal plate, Horizontal lid laxity from involutional changes of medial and lateral canthal ligament and Enophthalmos from atrophy of the orbital fat with age. In the correction of involutional entropion, the first three factors must be considered for adequate correction. Hsu and Lieu reported Pretarsal orbucularis oculi muscle fixation method for the correction of involutional entropion. Authors performed this method in the 20 patients with involutional entropion of thirty-one eyelids and the results were sucessful.
