The management of patients with thyroid eye disease after bilateral orbital 3 wall decompression.

INTRODUCTION

Thyroid eye disease is the most common cause of unilateral and bilateral proptosis in adults. Orbital decompression surgery may cause and/or worsen a pre-existing ocular motility disorder.

METHODS

A retrospective review was carried out of all bilateral 3 wall orbital decompressions for severe thyroid eye disease performed between January 2002 and December 2004 by one surgeon. Subsequent surgeries were recorded.

RESULTS

Seventy-four patients were identified, 59 (80%) females and 15 (20%) males. Mean age at the time of decompression was 46 years. Fifteen (20%) patients complained of diplopia due to strabismus prior to decompression surgery and 20 (27%) developed new diplopia postsurgery. Twenty patients (27%) required no further intervention following decompression surgery; the remainder underwent an average of 2.5 procedures. Strabismus surgery was performed in 32 (43%) patients. The mean time from the decompression to first strabismus surgery was 12 months. Forty-three (58%) patients underwent lid surgery. The mean time from decompression to first lid surgery was 16 months.

CONCLUSION

This study demonstrates how this group of complex patients required multiple surgical procedures within an extended timescale, therefore requiring several in- and outpatient visits.
