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 ...
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)
Feeling this would indicate an organic cause of the paresis. If the examiner does not feel the "normal" leg's heel pushing down as the patient flexes the hip of the "weak" limb, then this suggests functional weakness (sometimes called "conversion disorder"), i.e. that effort is not being transmitted to either leg. [citation needed]
Other causes of ptosis include eyelid neoplasms, neurofibromas or cicatrization after inflammation or surgery. Mild ptosis may occur with aging. A drooping eyelid can be one of the first signals of a third-nerve palsy resulting from a cerebral aneurysm that is otherwise asymptomatic, a condition known as oculomotor nerve palsy.
Exophthalmos (also called exophthalmus, exophthalmia, proptosis, or exorbitism) is a bulging of the eye anteriorly out of the orbit. Exophthalmos can be either bilateral (as is often seen in Graves' disease) or unilateral (as is often seen in an orbital tumor). Complete or partial dislocation from the orbit is also possible from trauma or ...
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
Facial synkinesis is a common sequela to Idiopathic Facial Nerve Paralysis, also called Bell's Palsy or Facial Palsy. [2] Bell's Palsy, which is thought to occur due to a viral reactivation which can lead (through unknown mechanisms) to diffuse axon demyelination and degeneration of the seventh cranial nerve, results in a hemifacial paralysis due to non-functionality of the nerve.
