Everting suture correction of lower lid involutional entropion

To assess the long term efficacy of everting sutures in the correction of lower lid involutional entropion and to quantify the effect upon lower lid retractor function.

A prospective single armed clinical trial of 62 eyelids in 57 patients undergoing everting suture correction of involutional entropion. Patients were assessed preoperatively and at 6, 12, 24, and 48 months postoperatively. The main outcome variables were lower lid position and the change in lower lid retractor function.

When compared with the non-entropic side, the entropic lid had a greater degree of horizontal laxity and poorer lower lid retractor function. These differences however, were not significant. At the conclusion of the study and after a mean follow up period of 31 months, the entropion had recurred in 15% of the patients. There were no treatment failures in the group of five patients with recurrent entropion. The improvement in lower lid retractor function after the insertion of lower lid everting sutures did not reach statistical significance. There was no significant difference between the treatment failure group and the group with a successful outcome with regard to: the degree of horizontal lid laxity or lower lid retractor function present preoperatively; patient age or sex; an earlier history of surgery for entropion. There was neither a demonstrable learning effect nor a significant intersurgeon difference in outcome. The overall 4 year mortality rate was 30%.

The use of everting sutures in the correction of primary or recurrent lower lid involutional entropion is a simple, successful, long lasting, and cost effective procedure.
