Von Graefe's sign

From Wikipedia, the free encyclopedia

Von Graefe's sign (lid lag sign) is the immobility or lagging of the upper eyelid on downward rotation of the eye, indicating exophthalmic goiter.[1]

A pseudo Graefe's sign shows a similar lag, but is due to aberrant regeneration of fibres of the oculomotor nerve (III) into the elevator of the upper lid.[2]
