The mechanism of action is best understood on a histological level of blood vessel anatomy.

However, if dilation does occur then the lesion is assumed to be preganglionic in nature. American Journal of Ophthalmology.


If the pupil does not dilate with hydroxyamphetamine then the lesion is postganglionic. Her extraocular motilities were again ainsocoria with no signs of restriction OU.

The third order neuron postganglionic leaves the superior cervical ganglion, ascends as a plexus surrounding the internal carotid artery to the cavernous sinus, jumps off onto the abducens nerve CN VI for a short course, then onto the ophthalmic branch of the trigeminal nerve CN V where the fibers travel via the nasociliary nerve through the superior orbital fissure.

Diseases of the human eye H00—H59 — Common differential diagnoses to consider are listed in Table 2. Her accommodative pupillary responses were normal OU as well. A thorough understanding of the oculosympathetic pathway is critical in understanding and detecting the underlying pathophysiology of Horner syndrome.


Kenneth Weston Wright, Peter H. The process of her stopping mid-race to bend down and tie her shoe may have set off her cascade of signs and symptoms. At seconds after the anosocoria have been put out, the anisocoria lessens as the sympathectomized pupil gradually caueas up, a process referred to as dilatation lag. Paralytic strabismus Ophthalmoparesis Chronic progressive external ophthalmoplegia Kearns—Sayre syndrome. Old photographs may be helpful in defining the duration of anisocoria asymmetry of pupillary size.

Walter George Bradley, She reported her ptosis was still evident, but improved, and that she had xnisocoria her pupils were now consistently the same size. Alexander DeLahunta, Eric Glass, Anisocoria is a common condition, defined by a difference of 0. Some of the causes of anisocoria are not life-threatening, including Horner’s syndrome which may be due to carotid artery dissection and oculomotor nerve palsy due to a brain aneurysm, uncal herniationor head trauma.

The blood in the ICA lumen then invades anisicoria space in the laminar wall creating a hematoma which typically dissects more distally, secondary to the direction of blood flow in the artery, than proximally, as well as for variable distances in the arterial wall.

Adnexal examination did reveal subtle upper lid ptosis OS when compared to the OD. Anisocoria has various causes: Curr Neurol Neurosci Rep. The miotic pupil in Horner syndrome occurs secondary to the unopposed innervation of the parasympathetic system, while the ptosis and anhidrosis findings are induced by the lack of sympathetic innervation in causaz.

Motor vehicle accidents are the most common cause of traumatic cases. Table 1 Most common causes of Horner syndrome. Her extraocular motilities were noted to have full range of motion in both eyes OU with no signs of restriction nor any complaints of diplopia. Journal List J Optom v. Pupils in Acute Brain Disease Pupillary abnormalities are Hydroxyamphetamine is the second drug used with Horner syndromes and has been used historically to localize the lesion after a positive cocaine test.

Oculosympathetic paresis, historically known as Horner sydrome, classically results in a triad of ptosis, miosis, and anhydrosis on the affected side. Ptosis, ocular motility disruption, pupil involved with aneurysmal compression, older individuals typically, history of vasculopathic causes diabetes, hypertension, hypercholesterolemia, etc.
