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 underwe...
