Adie's tonic pupil is usually associated with a benign peripheral neuropathy ( Adie syndrome ), not with syphilis. (wikidoc.org)
Adie's pupil is caused by damage to peripheral pathways to the pupil (parasympathetic neurons in the ciliary ganglion that cause pupillary constriction to bright light and with near vision). (wikidoc.org)
Neuro-ophthalmologists assess pupillary abnormalities, such as anisocoria (unequal pupil size) or abnormal pupillary responses, which may indicate underlying neurological issues like Horner's syndrome or Adie's tonic pupil. (rthm.com)
This can be seen in conditions like Horner's syndrome or Adie's tonic pupil. (rthm.com)
Pupillary6
These neurons supply the pupillary sphincter muscle, which constricts the pupil, and the ciliary muscle which contracts to make the lens more convex. (wikipedia.org)
The AR pupil is thought to be caused by damage to central pathways for pupillary constriction. (wikidoc.org)
The older literature on AR pupils did not report the details of pupillary constriction (brisk vs. tonic) that are necessary to distinguish AR pupils from tonic pupils. (wikidoc.org)
The evidence supports a midbrain cause of the AR pupil, provided one follows Loewenfeld's definition of the AR pupil as small pupils that react very poorly to light and yet seem to retain a normal pupillary near response that is definitely not tonic. (wikidoc.org)
To settle the question of whether the AR pupil is of central or peripheral origin, it will be necessary to perform iris transillumination (or a magnified slit-lamp examination) in a substantial number of patients who have a pupillary light-near dissociation (with and without tonicity of the near reaction), perhaps in many parts of the world. (wikidoc.org)
Dysfunction in the pupillary reflexes may occur, leading to abnormalities in the size (anisocoria) or reactivity of the pupils. (rthm.com)
Constrict9
When a person with an Adie pupil attempts to focus on a nearby object, the pupil (which would normally constrict rapidly) constricts slowly. (wikipedia.org)
A person with anisocoria (one pupil bigger than the other) whose pupil does not react to light (does not constrict when exposed to bright light) most likely has Adie syndrome - idiopathic degeneration of the ciliary ganglion. (wikipedia.org)
This means that every time the patient accommodates her gaze to a near object, some of the innervation to the ciliary muscle will spill over into the iris and constrict the pupil. (wikipedia.org)
Pupils get larger (dilate) in dim light and smaller (constrict) in bright light. (merckmanuals.com)
Argyll Robertson pupils ("AR pupils") are bilateral small pupils that constrict when the patient focuses on a near object (they " accommodate " with near vision), but do not constrict when exposed to bright light (they do not "react" to light). (wikidoc.org)
In the 1950s, Loewenfeld [4] distinguished between the two types of pupils by carefully observing the exact way in which the pupils constrict with near vision. (wikidoc.org)
These light-sensitive pathways allow the pupil to constrict to bright light. (wikidoc.org)
The accommodation pathways - pathways to the Edinger-Westphal nucleus that cause the pupils to constrict with near vision - are thought to be spared because of their more ventral course in the brainstem. (wikidoc.org)
Diseases of the ciliary ganglion produce a "tonic pupil", which is a pupil that does not react to light (it is "fixed") and has an abnormally slow and prolonged response to attempted near vision (accommodation). (wikipedia.org)
In such people, both pupils react normally to light and darkness and there are no symptoms. (merckmanuals.com)
They were formerly known as "prostitute's pupils" because of their association with syphilis and because, like a prostitute, they "accommodate but do not react. (wikidoc.org)
Pupils that "accommodate but do not react" are said to show light-near dissociation . (wikidoc.org)
In the early 20th century, Adie described a second type of pupil that could "accommodate but not react. (wikidoc.org)
This uncommon syndrome involves vertical gaze palsy associated with pupils that "accommodate but do not react. (wikidoc.org)
Iris2
These sensory axons supply the cornea, ciliary body and iris. (wikipedia.org)
Inflammation of the iris (iritis) and certain types of glaucoma cause unequal pupils, but this finding is usually overshadowed by severe eye pain. (merckmanuals.com)
Swollen1
Over time the cornea becomes edematous (swollen) causing blurred vision, and the rust from the metallic object becomes more embedded. (focusoptometry2020.com)
Unequal5
If pupil sizes are very unequal, a person may notice the discrepancy. (merckmanuals.com)
More often, unequal pupils are noticed only during a doctor's examination. (merckmanuals.com)
Unequal pupils themselves usually cause no symptoms, but occasionally a person may have trouble focusing on near objects. (merckmanuals.com)
These more noticeable symptoms are often the reason people seek medical care rather than the unequal pupils. (merckmanuals.com)
Eye disorders that cause unequal pupils include birth defects and eye injury. (merckmanuals.com)
Ciliary ganglion1
She noted that pathological destruction of nerve cells in the ciliary ganglion that is found in all cases of Adie pupil. (wikipedia.org)
Dilate1
When the person focuses on a more distant object (say the far side of the room), the pupil (which would normally dilate immediately) remains constricted for several minutes, and then slowly dilates back to the expected size. (wikipedia.org)
Loewenfeld2
The strange behavior of tonic pupils was first explained by Irene Loewenfeld in 1979. (wikipedia.org)
Based on these observations, Loewenfeld proposed an explanation of the tonic pupil. (wikipedia.org)
Blinks1
To help with pain a bandage contact lens is often placed on the patient's eye to minimize the pain that occurs when the eyelid blinks across the surface of the affected cornea. (focusoptometry2020.com)
Eyelid4
Horner Syndrome Horner syndrome affects one side of the face, causing the eyelid to droop, the pupil to become small (constricted), and sweating to decrease. (merckmanuals.com)
These pathways carry nerve impulses to the pupil and to the muscles that control the eye and eyelid. (merckmanuals.com)
Thus, people with nervous system disorders that affect the pupil often also have a drooping eyelid, double vision, and/or visibly misaligned eyes. (merckmanuals.com)
Horner syndrome refers to the combination of a constricted pupil, drooping eyelid, and loss of sweating around the affected eye. (merckmanuals.com)
Abnormal3
Either the larger or the smaller pupil may be the abnormal one depending on the cause. (merckmanuals.com)
If the larger pupil is abnormal, the difference between pupil sizes is greater in bright light. (merckmanuals.com)
If the smaller pupil is abnormal, the difference is greater in the dark. (merckmanuals.com)
Peripheral1
[5] It is not known whether neurosyphilis itself (infection by Treponema pallidum ) can cause tonic pupils, or whether tonic pupils in syphilis simply reflect a coexisting peripheral neuropathy. (wikidoc.org)

Pathways1
Specifically, the AR pupil is thought to be caused by selective damage to pathways from the retina to the Edinger-Westphal nucleus . (wikidoc.org)
Lens2
Casey a tonic in the center of cases on this is a concave lens. (lvmodernhomes.com)
It involves a change in the size of the pupil and the convexity of the lens, and either a convergence or divergence of the eyes. (unboundmedicine.com)
Reflex1
Also, touching the cornea itself should result in the corneal reflex (closing of the eyelids in response to the touching of the cornea). (vetsci.co.uk)

In the normal adult fissure, the highest point of the upper lid is just nasal to the center of the pupil, while the lowest point of the lower lid is just temporal to the center of the pupil. (medscape.com)
Size2
Usually both pupils are about the same size and respond to light equally. (merckmanuals.com)
The AR pupil became known as a reliable clinical sign of syphilis. (wikidoc.org)
