Stellwag’s Sign

Stellwag’s Sign

Stellwag’s sign is a widening of the palpebral fissure due to upper eyelid retraction. Along with a reduced blink rate, this creates a very typical staring, "astonished", facies. The clinical phenomena of Stellwag’s sign overlap with those labeled as the sunset sign.
Stellwag’s sign is seen in progressive supranuclear palsy, and in dysthyroid eye disease.
