Somatostatin mydriasis in mice
Life Sciences, 1983Administration of somatostatin intracerebroventricularly to mice produced a dose-dependent mydriasis, whereas intravenous injections were ineffective. Naloxone could prevent or abolish this effect. It is suggested that somatostatin either directly excites opiate receptors or activates endopioid pathways involved in the regulation of pupillary size.

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 ...

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.

Abstract In this case, a middle-aged male presents to an emergency department (ED) with eye pain, visual blurring, and photophobia following trauma to the eye the previous day. It is some time before the patient is seen because the ED is extremely busy. Some drops are instilled in the eye for pain relief.

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.

We report a case of plant poisoning with atropa belladonna. A student took the berries because of the hallucinogen effects. In this case report we describe the symptoms and the therapy of poisoning with atropa belladonna. Another part informs about the historic and cultural importance of this nightshade.

Mydriasis from Datura Wrightii
American Journal of Ophthalmology, 1977A 4-year-old girl had painless, uniocular mydriasis after picking flowers. Pharmacologic testing with 1% pilocarpine confirmed the probability that an atropine-like agent had been instilled in the affected eye. The flowers were identified as Datura wrightii and contained scopolamine, hyoscyamine, and atropine on thin-layer chromatography.

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 ...
