Figure 4. Cumulative Incidence of Strabismus, Strabismus Surgery, or Orbital Decompression Surgery After Diagnosis of Thyroid Eye Disease.

The cumulative incidence of strabismus as an outcome of thyroid eye disease increased to 10% during the first 4 years after diagnosis and then became stable at 12%. The cumulative incidence of strabismus surgery was 8% after 4 years and reached a maximum incidence of 10% after 8 years. The cumulative incidence of decompression surgery was steady at 5% after 4 years.
