In mild disease, patients present with eyelid retraction. In fact, upper eyelid retraction is the most common ocular sign of Graves' orbitopathy. This finding is associated with lid lag on infraduction (Von Graefe's sign), eye globe lag on supraduction (Kocher's sign), a widened palpebral fissure during fixation (Dalrymple's sign) and an incapacity of closing the eyelids completely ...
Lid lag is the static situation in which the upper eyelid is higher than normal with the globe in downgaze. [1] It is most often a sign of thyroid eye disease, but may also occur with cicatricial changes to the eyelid or congenital ptosis. Lid lag differs from Von Graefe's sign in that the latter is a dynamic process. It can also be the ...
What can make things particularly difficult, is that many patients with hyperthyroidism have lid retraction, which leads to stare and lid lag (due to contraction of the levator palpebrae muscles of the eyelids). This stare may then give the appearance of protruding eyeballs , when none in fact exists. This subsides when the hyperthyroidism is ...
Class 1: Only signs (limited to upper lid retraction and stare, with or without lid lag) Class 2: Soft tissue involvement (oedema of conjunctivae and lids, conjunctival injection, etc.) Class 3: Proptosis; Class 4: Extraocular muscle involvement (usually with diplopia) Class 5: Corneal involvement (primarily due to lagophthalmos)
The stare-in-the-crowd effect is the notion that an eyes-forward, direct gaze is more easily detected than an averted gaze. First discovered by psychologist and neurophysiologist Michael von Grünau and his psychology student Christina Marie Anston using human subjects in 1995, [1] the processing advantage associated with this effect is thought to derive from the importance of eye contact as a ...

It is a dynamic sign, whereas lid lag is a static sign which may also be present in cicatricial eyelid retraction or congenital ptosis. A pseudo Graefe's sign (pseudo lid lag) 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] It occurs in paramyotonia ...
