Factors associated with decompression and strabismus surgery in thyroid eye disease.
BACKGROUND
Prognostication of the thyroid patient with eye disease aids in the choice of treatment strategy. To facilitate this, we investigated factors associated with decompression and/ or strabismus surgery in the Singaporean population.


METHODS
A 5-year retrospective study was performed. Patients who required strabismus and/or decompression surgery (n = 23) were compared to those who did not undergo either surgery (n = 44). Individual and multivariate age-adjusted odds ratios were calculated to determine significant associations.


RESULTS
Individually, male gender [odds ratio (OR), 4.5; 95% confidence interval (CI), 1.5 to 13.4], uncontrolled hyperthyroidism (OR, 4.0; 95% CI, 1.1 to 14.3), steroid therapy (OR, 7.4; 95% CI, 2.3 to 24), diplopia (OR, 7.3; 95% CI, 2.3 to 23.1), objective vertical myopathy (OR, 11.7; 95% CI, 1.4 to 96.0), elevated intraocular pressure in the primary position (OR, 3.4; 95% CI, 1.2 to 10.0) and clinical evidence of optic neuropathy (OR, 13.1; 95% CI, 1.4 to 124.6) were significantly associated with the need for surgery. Logistic regression analysis showed the greater impact of male gender (OR, 4.2; 95% CI, 1.2 to 15.4), optic neuropathy (OR, 13.0; 95% CI, 1.2 to 143.7) and previous steroid therapy (OR, 4.2; 95%CI, 1.1 to 16.2) on prognostication.


CONCLUSIONS
Chances of requiring strabismus and/or decompression surgery are significantly higher for male patients and those with uncontrolled hyperthyroidism. In particular, male patients with optic neuropathy and a history of previous steroid therapy warrant a graver prognosis.
