[Senile ectropion and entropion].
Senile ectropium and entropium are a result of progressive loss of tissue elasticity in the lower lid of the aging patient. In case of ectropium slackening takes place near the lid margin, whereas entropium may develop if this process occurs at a certain distance from the lid margin. Based on these facts, wedge tarsectomy together with a lateral blepharorrhaphy as described by Kuhnt-Blascovicz is the logical treatment for ectropium, while a wedge resection of the tarsus plus formation of a tight muscle sling of the infratarsal portion of the orbicularis muscle is our preferred method to correct the entropium.
