Journal of Ocular Pharmacology and Therapeutics, 1985
In several rodent species pilocarpine and oxotremorine produce mydriasis, rather than the miosis which is characteristic of most other species. We have established that pilocarpine is a mydriatic drug in mice, a species in which the action has previously not been described, and that this effect occurs after local ocular, intraperitoneal (IP) or ...

Abstract In mice, morphine produces dose-dependent mydriasis. The mydriatic effect does not depend upon the integrity of the sympathetic system, and interference with central catecholamines or serotonin also does not abolish the response. Ro 4-1284, a neurotransmitter depletor, causes miosis and inhibits completely the response to morphine.

Bilateral Congenital Mydriasis
American Journal of Ophthalmology, 1976A 73-year-old white woman with bilateral congenital mydriasis had no other obvious abnormalities. The pupils reacted almost imperceptibly to light. There was no detectable reaction to accommodation and convergence. Pupillary response to pilocarpine 4% solution indicated the presence of the sphincter muscle. However, the failure of the pupil to react to

Clonidine mydriasis in the rat
European Journal of Pharmacology, 1979Pupillary responses to clonidine (3--100 micrograms/kg, i.v.) and epinephrine (1--30 micrograms/kg, i.v.) were observed in anesthetized rats. Clonidine caused a dose-dependent mydriasis which was effectively antagonized by pretreatment with yohimbine (1.5 mg/kg, i.v.).

A healthy 3-year old boy was brought to the emergency department because of an acutely dilated right pupil, which developed after he had played in the garden. Half an hour before presentation, his parents noticed he had been crying.

The Mydriasis Provocative Test
Archives of Ophthalmology, 1961Results of provocative testing in angle-closure glaucoma are presumed to depend on mechanical obstruction to the egress of aqueous. 1,2 Recent refinements of this test have hinged on recording a reduction in outflow facility prior to any elevation in intraocular pressure.

A dilated unreactive pupil is a dramatic clinical finding. While it can be seen in the setting of compressive third nerve palsy, it can also be due to pharmacologic mydriasis. We discuss the approach to the patient with suspected pharmacologic mydriasis, with an emphasis on the role of pharmacologic pupil testing.

Challenging case of unilateral mydriasis
Emergency Medicine Journal, 2019A 40-year-old female gardener presented with a 1-day history of a dilated left pupil (figure 1). She denied headaches, vomiting, double vision, eye pain or discharge. There was no history of topical eye-drops or trauma. On examination, her left pupil was 8 mm compared with her right pupil at 3 mm.

Effect of Pilocarpine in Counteracting Mydriasis
Archives of Ophthalmology, 1968The effectiveness of 1% pilocarpine in counteracting the mydriatic effect of phenylephrine hydrochloride (Neo-Synephrine Hydrochloride), hydroxyamphetamine hydrobromide (Paredrine), tropicamide (Mydriacyl), and homatropine hydrobromide in the concentrations ordinarily used in clinical ophthalmology was studied in 15 subjects.

Hydroxyamphetamine Mydriasis in Normal Subjects
American Journal of Ophthalmology, 1990Hydroxyamphetamine eyedrops are used to help localize the lesion in Horner's syndrome. Because normal variability in the response to the eyedrops may influence the interpretation of test results in patients with Horner's syndrome, we studied both the interocular variability of the drug's mydriatic effect within each normal subject and the variation ...
