Objective To examine the association of orbital decompression and the characteristics and outcome of subsequent strabismus surgery in patients with thyroid eye disease (TED). Methods Data on patients with TED who underwent orbital decompression at the Goldschleger Eye Institute, Sheba Medical Center, Israel, between January 1990 to December 2011 were extracted. The characteristics of decompression and strabismus surgeries were recorded. The outcomes and association of both surgical procedures were analyzed. Statistical analysis included distribution, Pearson correlation, and matched paired tests. Results 145 eyes underwent orbital decompression, of which 45 eyes (31.0%) underwent strabismus surgery. Esotropia developed in 70% of the patients. Men and smokers underwent strabismus surgeries after decompression procedures more frequently than women and nonsmokers (χ2 test, p = 0.07, 0.002). Moreover, patients who complained of diplopia before the decompression surgery underwent strabismus surgery more frequently (χ2 test, p = 0.005). Seventy-seven percent of the patients who underwent medial wall decompression developed esotropia (χ2 test, p = 0.004). Conclusions To the best of our knowledge, this is the largest series in the literature examining the association between decompression and strabismus surgeries. The patients’ characteristics and the orbital walls involved in the decompression procedures are associated with the characteristics of subsequent strabismus that develops thereafter. These findings may have significant implications in planning TED management.
