Early strabismus surgery for thyroid ophthalmopathy.

OBJECTIVE

To determine whether strabismus surgery during active thyroid ophthalmopathy is beneficial for selected patients.

DESIGN

Case series.

PARTICIPANTS

Eight patients with severe restrictive strabismus due to thyroid ophthalmopathy underwent early strabismus surgery and were followed for a minimum of 16 months after their initial surgery.

INTERVENTION

All eight patients underwent strabismus surgery while their thyroid ophthalmopathy was evolving.

MAIN OUTCOME MEASURES

Success was determined by the ability to fuse in the primary position at distance and near without an abnormal head position, and the absence of vision-threatening complications related to strabismus surgery.

RESULTS

All eight patients achieved successful long-term alignment. Four patients (50%) required more than one operation.

CONCLUSIONS

Strabismus surgery during active thyroid ophthalmopathy can result in long-term stable alignment and may be a useful alternative in selected patients with marked disability due to thyroid ophthalmopathy.
