Are migraine auras also considered phosphenes? e.g., the classic scintillating scotoma…? — mjb 16:54, 19 December 2006 (UTC)
What is "a crumpling fly-spotted flyscreen"? Not really a good metaphor since it's not universally understood. User: petruchi41 15:07 EST 16 April 2007
This is not the same as visual snow, some people may have both, but they are different. —Preceding

I also wanted to add that phosphenes and visual snow are not the same thing, so please do not merge the articles. -- AliisaKissa ( talk) 01:13, 21 October 2008 (UTC)
Shouldnt the danger of damage to retina etc from pressing eyeballs be pointed out? Detached retinas are a serious medical condition.
Does this also have to do with seeing what looks like different colored glitter when you rub your eyes or press on them? I guess that might be a form of what people call seeing stars. Violet yoshi ( talk) 07:17, 14 February 2008 (UTC)
The example image image:Phosphene_artistic_depiction.gif seems to be completely inaccurate (based on what i've seen and the description), and is more suitable for the page on Form_constants. 68.18.66.216 ( talk) 07:45, 31 May 2008 (UTC)
I am disappointed that this site and others have taken down this image. I'm glad it's still here in the history, because I want to take it to show my doctor. This is almost exactly what I see. It's been about four times now and I don't know what's causing it. 114.43.108.243 ( talk) 00:40, 6 June 2010 (UTC)SKBOX, 06/06/10
I dont think this image has any relation with phosphenes. In my own experienced phosphenes I saw coloured or silver dots zooming in. (Very far from black and white squares).That being said, the picture is very good and if you stare at it, when you look away, it triggers some similar effect. Would it be out of the line to mention this in the image description? Unmismoobjetivo ( talk) 04:52, 1 June 2013 (UTC)
Some people report being able of changing the visual patterns more or less at will while keeping the pressure on the eyes during the entoptic phenomenon. The following text could shed some light into this possibility:
"Mathematician G. Bard Ermentrout explains that the pressure inhibits signals from the retina, thereby encouraging the brain's cortex to fill the void. The brain begins firing spontaneously and creates hallucinatory patterns." [1]
It's evident that the initial pattern is created by one of the mechanisms listed in the article, e.g. pressure on the eyes. But then, perhaps due to the oddity and incoherence of the samples, the visual cortex is open to filling the voids with information such as the thoughts from the conscious mind. This would explain why some subjects may be able to control the content of these visions, to some extent.
Does anyone know of any research or works on this subject? It might be of interest in the study of the visual cortex.— Preceding unsigned comment added by 81.33.113.238 ( talk) 23:33, 20 September 2009 (UTC)
Hi wikipedia. I have phosphenes too!

I've been trying to nail down the coining of the word phosphene. I believe that this page cites the wrong person. I have a copy of the original report from 1838, and only M. (Monsieur) Savigny is referenced. I believe that this is Marie-Jules-César Lelorgne de Savigny who is documented as being blind (which is referenced in the original report). I think that attribution of this report to Jean Baptiste Henri Savigny is incorrect. I have not been able to confirm this suspicion yet. Please confirm and correct. This error is widely cited across the internet. — Preceding unsigned comment added by DrYoda ( talk • contribs) 11:36, 3 July 2018 (UTC)
