[Pathogenesis of and causal surgery for senile entropion by en bloc resection (author's transl)]

The pathogenetic factors responsible for senile entropion are: age-induced relaxation of the lower lid structures with elongation of the lid and improper loose adaptation between lid margin and globe, a weak tarsal plate and a lower stimulus threshold of the facial nerve. A surgical intervention which consists of radical lid-shortening by an bloc tarsal resection seems to be the most logical procedure. It was performed on 285 patients. The methods results in a lower rate of recurrence, normalizes lacrimal flow and has an excellent cosmetic side-effect improving the configuration of the lid-fissure. A special indication exists for cases in which there is a relapse following surgery.
