Q
When anisocoria is present… and the larger
When faced with anisocoria, what do you want to know first and foremost?Which pupil (if either) is ‘the culprit’; ie, is the larger pupil failing to constrict properly, or isthe smaller pupil not dilating properly?
How can you tell which pupil is the culprit?By determining the lighting condition under which the anisocoria is more pronounced. Ifthe anisocoria is more pronounced in dim light, this indicates the smaller pupil isn’t dilatingproperly (and thus is abnormal). A pupil that fails to dilate is suggestive of a sympatheticpathway problem. Likewise, if the anisocoria is more pronounced in bright light, the largerpupil isn’t constricting properly, and is therefore abnormal. A pupil that doesn’t constrict asit should is suggestive of a parasympathetic pathway problem.
What if the anisocoria is the same under all lighting conditions?Then it is nonpathologic or physiological anisocoria--a common finding

Wait a minute. According to Step 1, an Adie’s pupil constricts with dilutepilo. The reason we tested this pupil with full-strength pilo was that it failed to constrict to dilute pilo. So how can it be an Adie’s pupil too?Adie’s syndrome involves interruption of the parasympathetics to the eyeafter the ciliary ganglion. The absence of input produces denervationsupersensitivity of the receptors at the pupillary constrictor muscle, soa chronic Adie’s pupil will respond to dilute pilo. However, denervationsupersensitivity takes time to develop; thus, an Adie’s of recent onset(a so-called acute Adie’s) will not respond to dilute pilo, but will to fullstrength.

What is light-near dissociation?A phenomena in which pupils miose less robustly in response to light than they do as part of the near response
What are the three general types /locations of light-near dissociation?--Afferent--Central--Peripheral
Where in the brain is the lesion in a central near-light dissociation?The dorsal midbrain region
What specific structure of the dorsal midbrain is involved?The pretectum
What is the eponymous name for the syndrome caused by a dorsal midbrain/pretectum lesion?Parinaud syndrome
What are the two noneponymous names for Parinaud syndrome?1) Dorsal midbrain syndrome2) Pretectal syndrome
The etiology of a Parinaud syndrome is often a function of who the pt is.For each of these pts with Parinaud’s, state the most likely cause:--A child: Hydrocephalus--A young man: A pineal tumor--A young woman: MS--An older man: CVA
Parinaud syndrome has four classic clinical features. One is light-near dissociation. What are the other three?--Light-near dissociation--Impaired upgaze--Lid retraction--Convergence-retraction nystagmus

What does it mean to say the near response is tonic?It means the pupil’s miotic near response persists even after the eye is no longer engaged in attempting to see at near, with re-dilation occurring s-l-o-w-l-y
Under what circumstance does a tonic pupil earn the distinction of being an ‘Adie’s’?When it is idiopathic, ie, when no identifiable cause can be found

What does it mean to say the near response is tonic?It means the pupil’s miotic near response persists even after the eye is no longer engaged in attempting to see at near, with re-dilation occurring s-l-o-w-l-y
Under what circumstance does a tonic pupil earn the distinction of being an ‘Adie’s’?When it is idiopathic, ie, when no identifiable cause can be found

Adie’s pupil stems from disruption of postganglionic parasympathetics in the orbit. Acutely, this results in a loss of both pupillary constrictor function (hence the fixed dilated pupil) and accommodation (hence the difficulty at near). However, over time several developments change the clinical picture. Denervation supersensitivity may develop, as described previously. In addition, aberrant regeneration can occur.
To what does aberrant regeneration refer in this context?The vast majority of orbital postganglionic parasympathetic fibers are dedicated to accommodation. Because of this, regeneration results in a number of accommodation-fiber-to-constrictor-muscle connections. This results in the tonic near response, miosis, and light-near dissociation of the chronic Adie’s pupil.

However, over time several developments change the clinical picture. Denervation supersensitivity may develop, as described previously. In addition, aberrant regeneration can occur.
To what does aberrant regeneration refer in this context?97% of orbital postganglionic parasympathetic fibers are dedicated to accommodation. Because of this, regeneration produces a number of inadvertent accommodation-fiber-to-constrictor-muscle connections. This results in the tonic near response, miosis, and light-near dissociation of the chronic Adie’s pupil.
