Convergence-retraction nystagmus: Attempts at upward gaze often produce this phenomenon. On fast up-gaze, the eyes pull in and the globes retract. The easiest way to bring out this reaction is to ask the patient to follow down-going stripes on an optokinetic drum. [9] Eyelid retraction (Collier's sign)
Photo showing the classic finding of proptosis and lid retraction in Graves' disease. Graves' ophthalmopathy is characterized by inflammation of the extraocular muscles, orbital fat and connective tissue. It results in the following signs, which can be extremely distressing to the patient: [4]
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 ...
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 ...
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)
Hyperthyroidism, associated with exophthalmos, periorbital puffiness, lid retraction, and lid lag; Cavernous sinus thrombosis, associated with infection of the paranasal sinuses, proptosis, periorbital oedema, retinal haemorrhages, papilledema, extraocular movement abnormalities, and trigeminal nerve sensory loss

Collier's sign (also known as Collier's tucked lid sign [1] or posterior fossa stare [2]) is bilateral or unilateral eyelid retraction. It is an accepted medical sign of a midbrain lesion, first described in 1927 by J Collier. [ 3 ]
