Abstract
BACKGROUND/PURPOSE: To compare the outcomes of strabismus surgery in patients with Graves' ophthalmopathy (GO) who had undergone bone removal orbital decompression (BROD) or fat removal orbital decompression (FROD) with those who had not undergone any orbital decompression. METHODS: The records of patients with GO who underwent strabismus surgery over a period of 66 months were retrospectively reviewed. RESULTS: Eighty-nine patients with a mean age of 55.1 ± 11.9 years were identified in this study. Twenty-two patients had prior BROD, 20 patients had prior FROD and 47 patients had no orbital decompression. Patients who had prior orbital decompression had an average of 1.6 strabismus surgeries per patient which was significantly higher compared to 1.2 strabismus surgeries in patients who had no orbital decompression (p = 0.02). The overall success rate of strabismus surgery was 68.2%, 80.0% and 80.9% following BROD, FROD and no orbital decompression respectively. The overall success rate of strabismus surgeries in patients with GO was 61% after the first surgery and 78% after the final surgery. CONCLUSION: The management of strabismus in GO is complex and difficult. Prior orbital decompression is associated with more strabismus surgeries per patient with a trend towards a lower success rate for strabismus surgery. FROD is comparable to BROD with regards to its effects on the outcome of subsequent strabismus surgeries.
