Palpebral asymmetry and hyperthyroidism. Two cases in connection with Graves' disease.

The causes of eyelid retraction or ptosis are numerous. Eye changes associated with thyroid dysfunctions are frequent, and diagnosis is not difficult in patients who are thyrotoxic. In euthyroid patients more difficulty may be encountered, especially if the disorder is asymmetric. The cases are described of two patients with ptosis and eyelid retraction on the other side, who suffered from thyroid disorder.
