Lid Lag

Lid Lag

Lid lag is present if a band of sclera is visible between the upper eyelid and the corneal limbus on attempted downgaze (cf. lid retraction), seen for example in thyroid eye disease (von Graefe’s sign), progressive supranuclear palsy (Steele-Richardson-Olszewski syndrome), and Guillain-Barré syndrome.
