Ideal sources for Wikipedia's health content are defined in the guideline Wikipedia:Identifying reliable sources (medicine) and are typically review articles.

Other potential sources include: Centre for Reviews and Dissemination and CDC

The User From 70.113.91.208 suggested in the article text that the spelling "myosis" is more correct than "miosis" (as "myopia"). There is already a redirect from myosis to miosis. I'm unable to say which is more correct or current; Google has many more hits for miosis, but Google is no authority. For now I've moved the notion to here. These sorts of discussions should always take place on the talk page, never within the article text. - toh 18:35, 15 November 2005 (UTC)[reply]

For what it's worth, AHD lists myosis as a variant form for miosis, not vice versa. [1][2]

edit: Actually, the correct form is more likely to be "miosis", as it is a simplification from the greek word "meiosis" which means 'reduction'. It is common particularly in american english to simplify diphthongs when translating a word into medical jargon (cf. faeces-feces, coelom-celom, anaesthetic-anesthetic etc). Oddly enough, "meiosis" is still used unaltered in the context of chromosome division. The spelling "myosis" would literally mean "a condition of muscle", since the first part is "mys" which means 'muscle' in greek (cf. myalgia, for instance). Although, I suppose, muscle does come into play in this condition, I would suggest that the user who suggested the spelling 'myosis', was simply a victim of hypercorrection. —Preceding unsigned comment added by 77.102.173.63 (talk) 04:51, 28 September 2007 (UTC)[reply]

Regarding the header suggesting that Miotic be redirected to Miosis, weak oppose. "Miotic" refers to a class of a drug that causes miosis, but miosis may occur due to non-pharmacological reasons. I'll bring this up in Wikipedia:WikiProject Drugs in an attempt to achieve a consensus. -AED 01:09, 14 November 2006 (UTC)[reply]

Weak oppose as well. Perhaps the miotic article could be expanded, with a note on mechanism of action of miotics, maybe a list of drugs used for this purpose/which induce miosis? Maybe one of our resident ophthalmologists could help? Fvasconcellos 14:24, 14 November 2006 (UTC)[reply]

Later this week I'll be uploading a picture of myself with abnormally constricted pupils. I am undergoing reconstrive burn surgery and should get a decent high resolution shot of my opioid-analgesic induced pinpoint pupils. For analgesia, I will most likely be infused with four milligrammes of intravenous hydromorphone (Dilaudid) and will be prescribed take-home painkillers, most like OxyContin.

Just some good news so we'll have a decent picture for the page... if anyone could help with formatting/advice on taking a good macro picture using a 5.4 megapixel 3x optical zoom Sony Cybershot that would be much apprecciated. I have a tripod stand, and plan to use a self-timer.

Anything else? :-)

The name and classification of the drug

This article is too technical. A wiki flag is needed on this page to identify it as needing a rewrite. Thanks! —The preceding unsigned comment was added by 149.136.25.254 (talk) 20:10, 23 April 2007 (UTC).[reply]

the mechanism should be added: namely, parasympathetics cause stimulation of muscarinic receptors on sphincter (aka circular) muscle, causing constriction that makes the pupil smaller. this is not to be confused with sympathetic stimulation of alpha1-receptors on the radial muscle. that muscle, too, is stimulated to constrict, but the effect is widening of the iris and pupil dilation. rhetoric 23:35, 7 November 2007 (UTC)[reply]

MAO"I" = MAO "I"nhibitors

The "I" in "MAOI Inhibitors" is redundant. —Preceding unsigned comment added by Sarindam7 (talk • contribs) 06:04, 10 December 2007 (UTC)[reply]

From my understanding, drugs like cocaine cause pupil dilation because of their vasoconstriction effect. Why does heroin constrict the pupils? Is it a Vasodilator? 67.5.156.112 (talk) 20:57, 9 January 2008 (UTC)[reply]

you should try to get a non-horner's picture to eliminate confusion. 128.125.28.186 (talk) 23:43, 31 March 2012 (UTC)[reply]

This revision added imidazolines as drugs which cause miosis, however I can't find a source for this and it appears to be incorrect.

Here's a study showing that clonidine (an imidazoline) causes mydriasis: https://www.ncbi.nlm.nih.gov/pubmed/931708

There are some indications that imidazolines can cause rebound miosis - but they would first cause mydriasis and the rebound occurs when you cease taking them.

This part should be clarified or removed.

The opposite condition, mydriasis, is the dilation of the pupil. Anisocoria is the condition of one pupil being more dilated than the other.

Why is there an ophthalmology lesson in the miosis article? It should be removed. Pixel0525 (talk) 09:20, 15 May 2023 (UTC)[reply]
