Long-term Outcomes of Surgical Approaches to the Treatment of Floppy Eyelid Syndrome

Abstract

To identify and describe the different procedures used in the treatment of floppy eyelid syndrome (FES) at Moorfields Eye Hospital and to evaluate their effectiveness. Cross-sectional study. A total of 71 patients who had undergone surgery for FES over a 13-year period since 1995 at Moorfields Eye Hospital were recruited. Retrospective data from 7 patients were also included, providing data for 78 patients. Patients underwent a full ocular examination. A survival analysis was determined by plotting Kaplan-Meier curves for each type of procedure encountered. Comparison of survival trends was made using a log-rank test. The possible effects of bias arising from bilaterality of the condition were investigated using a sensitivity analysis and a Cox regression analysis allowing for clusters. Tests for surgeon bias were made using the Fisher exact test. Recurrence of the condition. An assessment of recurrence was made clinically by 2 independent observers who were masked to the type of surgery the patient had undergone. Four different forms of surgical treatment were encountered: (1) Full-thickness wedge excision (FTWE) (26 patients, 33 procedures); (2) Upper lid lateral tarsal strip (LTS) (31 patients, 43 procedures); (3) Medial canthal (MC) and lateral canthal (LC) plication (15 patients, 19 procedures); (4) Medial tarsal strip (6 patients, 6 procedures). A total of 44 of 101 procedures had failed. Superior long-term survival outcomes of both LC/MC plication (P = 0.003) and upper lid LTS (P = 0.001) procedures over FTWE was demonstrated. However, survival comparison between the LC/MC plication and LTS groups did not achieve significance (P = 0.37). No significant difference in outcome between surgeon groups of equivalent experience was demonstrated (P = 0.18). No bias arising from bilaterality of the condition was identified. These data provide strong evidence of better survival outcomes in FES using the MC/LC plication and LTS procedures in comparison with the FTWE procedure. On the basis of experience from our unit, we recommend that the FTWE procedure be avoided as a form of treatment for FES in favor of the MC/LC plication, LTS, or medial tarsal strip procedure.
