Introduction
Lid lag, Von Graefe’s sign, stare, and lagophthalmos can be useful eyelid findings when evaluating a patient with thyroid eye disease. While they characteristically occur in patients with Graves’ disease, it is important to note that these signs are not pathognomonic for thyroid eye disease.1 Lid lag can be less commonly caused by congenital blepharoptosis from a fibrotic levator muscle, and lagophthalmos can occur from a lesion to the facial nerve or iatrogenically from an overaggressive upper blepharoplasty.2,3
Graves’ orbitopathy or thyroid eye disease is an autoimmune disorder that occurs in about 1/4th of patients with a hyperactive thyroid in Graves’ disease.4 However, thyroid eye disease can sometimes occur in patients with hypothyroidism (e.g., Hashimoto’s).5 In Graves’ disease, the thyroid-stimulating hormone receptor antibodies activate fibroblasts in the tissues behind and around the eye or globe. This results in inflammation, swelling, and volume expansion of the retroorbital tissues. This tissue presses on the back of the eye causing it to be pushed out. This bulging of the eye anteriorly is known as “proptosis” or “exophthalmos”. Lid lag and stare, however, are believed to be caused by excess thyroid hormone and not necessarily from the proptosis.6 The elevated thyroid hormone levels are believed to increase the contraction of the eyelid muscles, which is likely why treatment of the hormone levels can relieve the symptoms of lid lag and stare.6
The active phase is marked by eye redness, pain, and swelling. These symptoms can increase and decreases in intensity during this phase. Smoking cessation is important in management as the phase typically lasts 1 year for non-smokers and 2-3 years for smokers.5
Lid Lag
Lid lag is a static condition in which the upper eyelid is higher than normal while the eye is in downgaze.7 Lid lag can be measured by comparing the upper eyelid position in downgaze to its position in primary gaze relative to a fixed point like the pupil.1 Lid lag happens when there is increased contraction of the levator palpebrae muscles of the eyelids.6 Lid lag subsides when the hyperthyroidism is treated.6
A term often confused with lid lag is von Graefe’s sign. Von Graefe’s sign is dynamic rather than static.7 It is observed when the eye actively moves inferiorly from primary gaze and the upper eyelid follows at a slower-than-normal rate. The superior part of the iris (superior limbus) is often exposed during this slowed movement.1 Once the downgaze is fixed, and if the eyelid remains elevated, it may then be called “lid lag”.
Stare
Stare is the term used to describe the appearance of a patient with excessive eyelid retraction.6 The increased tightness of the levator palpebrae that causes lid lag can also give the patient this “staring” appearance. It is important not to confuse this with proptosis (bulging of the eye out of the socket) as they are two distinct conditions and can occur one without the other.6 Stare, like lid lag, subsides when the hyperthyroidism is treated.6
Lagophthalmos
Lagophthalmos is the inability to completely close the eyelids.1 Excessive upper lid retraction in thyroid eye disease can result in lagophthalmos and corneal exposure even while the patient attempts to close their eyes.
