  Mydriasis and Anisocoria: Autonomic Dysfunction - Neurology and Neurosurgery Forum
Pupil size is determined among other things, by adrenergic tone and in my case the mydriasis and anisocoria are likely to be the result of a disruption in parasympathetic innervation.
One potential danger of drug-induced mydriasis is the exacerbation of acute angle glaucoma in patients over 50 years old.
However, in case reports from the literature the mydriasis should resolve with discontinuation of the drug and at 2 months, the medication should already be out of your system.

Mydriasis is an excessive dilation of the pupil due to disease or drugs.
Damage to this nerve typically manifests itself as mydriasis, because the sympathetic supply to the pupil which causes mydriasis remains unaffected, and therefore unopposed.
The mydriasis caused by cocaine is used as a diagnostic test for Horner's Syndrome, in which the pupil is not dilated by cocaine.

 Trazyl, eyewash
Pre-surgery mydriasis: in cases of cataract extraction under local anesthesia, ibopamine 2% may be used alone as the only dilating treatment, or combined with other mydriatic agents having different action mechanisms, and should be administered according to the following posologic regimen: 1 or 2 drops 60, 30 and 5 minutes prior to surgery.
Provocative test in glaucoma diagnostics: the ibopamine test should be performed administering 2-drop doses of eyewash 2% at 5-minute intervals and comparing the intraocular pressure measured 45 minutes after the instillation to the baseline values for this parameter.
Mydriasis reversion may be obtained by administering eyewashes containing a-blocking substances.

 Mydriasis
Dilation of pupils - mydriasis — when in daylight or artificial illumination, their diameter is more than 4 mm (that is more than 33 % of the iris diameter), and can be caused by several reasons:
Unilateral mydriasis is of interest for topic diagnosis of the central nervous diseases system and is a part of a number of syndromes: Pty's, Notnaghel's, of superior orbital fissure, of external wall of sinus cavernous, Webber's, Benedict's, neuritis of optic nerve and paralysis of oculomotor nerve, post-traumatic encephalopathy.
Diagnosis of unilateral miosis or mydriasis, which is a part of multi-component clinical syndromes, is rather easy.

 Reduced mydriasis from repeated doses of tropicamide and cyclopentolate.
The pupils of the eyes twice-treated with tropicamide were an average of 0.15 mm smaller than the control pupils; those twice-treated with cyclopentolate were 0.36 mm smaller.
For subjects treated with cyclopentolate, this decreased mydriasis was related to age (P less than.05) and to eye color (P less than.025): the younger and blue-eyed subjects dilated less on the second day than the older and brown-eyed subjects.
If full mydriasis is required at surgery, pupils should probably not be dilated with either tropicamide or cyclopentolate the day before surgery.

 Accidental Pharmaceutical Mydriasis
The differential diagnosis was therefore Adie's tonic pupil, a third nerve palsy or pharmacological mydriasis.
Failure of the pupil to constrict to a diluted preparation of topical pilocarpine 0.125% excluded the denervation hypersensitivity seen in Adie's pupil, this was made in the department by mixing one drop of pilocarpine 1% with seven drops of saline.
Therefore a diagnosis of accidental pharmaceutical mydriasis was made and the reduced visual acuity could be explained by his paralysed accommodation and the optical aberrations normally seen in a dilated pupil.

 MYDRIASIS, HYPERTENSION, AND TACHYCARDIA POSSIBLY ASSOCIATED WITH VENLAFAXINE AUGMENTATION OF MIRTAZAPINE
As of September 27, 2004, this is the first case of hypertension after venlafaxine augmentation of mirtazapine and the first case to report a preceding mydriasis.
We propose an excess of noradrenergic activity due to the combination of venlafaxine and mirtazapine to be the most probable cause.
Mydriasis may be a good premonitory sign for hypertension.

 CAT.INIST
Clonidine (0.03 mg/kg, IP)-induced mydriasis was inhibited in a dose-related fashion by the α[2]-adrenoceptor antagonists, idazoxan (0.03-3 mg/kg, IP) and yohimbine (0.03-3 mg/kg, IP), but was unaltered by the α[1]- or β-adrenergic antagonists, prazosin (1 and 3 mg/kg, IP) or pindolol (1 and 3 mg/kg, IP).
Methamphetamine (0.75 mg/kg, IP)-induced mydriasis was similarly inhibited by idazoxan (1 mg/kg, IP) and yohimbine (1 mg/kg, IP).
The synaptic location of these receptors was determined using DSP-4 (50 mg/kg×2, IP) to lesion noradrenergic neurones: this produced a 64% depletion of noradrenaline in the midbrain (containing the Edinger-Westphal nucleus responsible for mydriasis) and reduced the mydriatic effect of methamphetamine (0.75 mg/kg, IP) to a similar extent (72%), whereas clonidine mydriasis remained unaltered.
