Talk:Micropsia

Possible Revisions

You mentioned there are drugs being that block vascular endothelial growth factors being evaluated as a treatment option in your current and future research section. Can you go into more detail about how this mechanism works at the cellular level in relation to vision improvements? Lildevil3221 (talk) 01:58, 23 November 2009 (UTC)

Further details describing the mechanism behind blocking vascular endothelial growth factors as a treatment option would be more appropriate on the wiki page for VEGF or macular degeneration rather than on the wiki page of the resulting symptom Micropsia.

A lot of useful information on micropsia can be found in the paper by Ugarte M, Williamson TH, Horizontal and vertical micropsia following macula-off rhegmatogenous retinal-detachment surgical repair. This study quantifies the degree of dysmetropsia in the vertical and horizontal meridians independently and offers insight into a possible theory centered on a decrease in photoreceptor density that may lead to less stimulation in a certain region of the eye in some post-eye surgery patients that may lead to the phenomenon of micropsia. Another paper by de Wit G.C, Retinally-induced aniseikonia, also provides useful information along the same lines that may fit under the causes or physiology section of your article.

Thanks for the input. The information from that article has now been included into the causes section with it as a reference.Giantsjs2000 (talk) 17:22, 26 November 2009 (UTC)

I worked on macropsia, the sister disorder to micropsia, so I understand the variety of ways these visual disorders can come about, and also the variety of ways it can be diagnosed. While you mention some good examples of how to diagnose micropsia, I would suggest mentioning the Amsler Grid Test in your "Diagnosis" section. This is a way to come to a diagnosis, even a self-diagnosis, without the use of costly medical exams with advanced equipment. More information on Amsler Grids, and what micropsia looks like on, one can be found here: [[1]]. Overall, this article is very detailed and well-written.

Thanks for the information. I just added the amsler grid test as a way to diagnose macular degeneration, a cause of micropsia. Farnhach (talk) 00:14, 3 December 2009 (UTC)

There seem to be a few redundancies between the introduction and the actual article. Perhaps making the introduction as more of a lead-in to the actual article rather than stating a summary could be more effective. In the "causes" section, you say that use of hallucinogenic drugs could also contribute. There was only a little blurb in the last sentence of the second to last paragraph. There is a little bit on how LSD may cause visual abnormalities in this site http://priory.com/psychiatry/Psychosis_and_Hallucinogens.htm which could be used as a secondary source. —Preceding unsigned comment added by Justindchien (talk • contribs) 20:31, 29 November 2009 (UTC) A few things in the "current and future research" section also overlap with "treatments." if you can combine the two into another subset of "future treatments," the later part of the "current and future research" section could be less confusing when it feels like some of those issues should have been addressed in the other section. Overall, a good improvement to the previous article. Justindchien (talk) 01:21, 29 November 2009 (UTC)

Thanks for the organizational advice. We are working on making our article as concise as possible and will take your suggestions into account when doing so. CharlesWCII^talk 02:48, 29 November 2009 (UTC)

Hey guys, great article. I found another article that may help. It goes into detail in how prism correction is a possible treatment for micropsia. Other causes for micropsia are discussed, including MS. The article is called "Presumed Ocular Myasthenia and Micropsia A Case Report" by Michaeli-Cohen, Adi M.D.; Almog, Yehoshua M.D.; Loewenstein, Anat M.D.; Stolovitch, Chaim M.D.; Gutman, Izaac M.D.; Lazar, Moshe M.D. Here is the link http://journals.lww.com/jneuro-ophthalmology/Abstract/1996/03000/Presumed_Ocular_Myasthenia_and_Micropsia_A_Case.5.aspx. Just click for the pdf file. chengkd (talk) 9:50, 28 November 2009 (UTC)

That is an interesting treatment that I had not come across in our research. Thanks a lot for the article. We have added the information to the "Treatment" section. CharlesWCII^talk 04:48, 29 November 2009 (UTC)

Hey, your article is very informative, but I agree with a comment above that you are redundant at times, but the comment above covers that well. I think something you guys could focus more on is finding more specifics at the cellular level of what actually occurs. What I mean is that your page lists many of the causes of micropsia, which is great, but there is a lack of detail as to what specifically happens, such as what pathways are affected that cause a migraine to then cause micropsia to result? What changes occur in the brain that result in micropsia? Other than trying to be more specific, your article is well-done. Widrickm (talk) 17:44, 29 November 2009 (UTC)

Thanks for the suggestion. Studies that look into the mechanisms behind micropsia have been difficult to come by so far, but we are still looking and would be eager to add any research explaining the pathway(s) behind the condition to our article. CharlesWCII^talk 18:50, 29 November 2009 (UTC)

Hey this is a great article with interesting statistics and facts. In the introduction the wording of the last sentence makes it seem as though hemi-micropsia(micropsia localized to one side)can be caused by AIWS and also macropsia, but does macropsia does not specifically cause hemi-micropsia instead of micropsia. I think a comma change fixes the problem. Also, you correctly mention that dissociative phenomena are related to micropsia. I wonder if you can go into some specifics about this in the rest of the article. Maybe mention how the condition can affect the everyday life or personality of someone who suffers from micropsia. the This link summarizes the sort of thing I am talking about http://ajp.psychiatryonline.org/cgi/content/abstract/118/3/232. Also, you may want to briefly mention something about this abstract http://www.pep-web.org/document.php?id=paq.046.0580a Sunderv (talk) 01:03, 30 November 2009 (UTC)

The article you listed from psychiatry online was very helpful in determining the psychological factors involved with micropsia. Thanks for the input! Farnhach (talk) 00:17, 3 December 2009 (UTC)

Cool article on a cool disorder! You guys did a great job including a good amount of links to other Wiki topics. The Pathophysiology section seems to unnecessary though. Pathophysiology is about the functional changes a disease causes; so essentially the Causes section covers whatever information the pathophysiology secion would cover. Also, the Epidemiology section seems too short; you could combine it with Diagnosis. You mention micro/macropsia occurs in 9% of adolescents, is this considered a high or low percentage? And is the majority of the cause inherently chronic or caused by hallucinogenic drug use in adolescents? Overall really neat article, especially integration of Alice in Wonderland. Good job! (Wangtron (talk) 01:14, 30 November 2009 (UTC)) Great article. Along the lines of what others have said, some details can be taken out of the introduction and moved to the body of the article and would help introduce it better. The epidemiology section can be added to with more statistics or merged with another section. Also, some additional information can be added about the different causes such as which cause is most common, which is most severe, most easily treatable, etc. Otherwise great job. Pmcb97 (talk) 01:28, 30 November 2009 (UTC)

Thanks for the suggestions. Once we have finished editing we will fix the introduction to be less detailed and fit better with our article. The epidemiology section is currently being expanded as we find more information about it. The causes section will also be altered to include more detail about the main causes of the condition. Farnhach (talk) 03:36, 30 November 2009 (UTC)

The paper that was mentioned earlier about retinally induced aniseikonia seems to give more insight about the micropsia caused at a retinal level, which could be incorporated in this wiki. It shows that for some conditions the amount of micropsia may depend on the (angular) size of the object. Also it mentions that in some cases of micropsia it might help to magnify the image in one eye optically to match the perceived image size in one eye better with the other eye. The article was published in 2007 in the journal Binocular Vision & Strabismus Quarterly, but can also be viewed from: http://www.opticaldiagnostics.com/info/ri_aniseikonia.pdf —Preceding unsigned comment added by AhiparaNZ (talk • contribs) 18:57, 14 April 2010 (UTC)

Causes

Being expanded well. Causes section needs to be ordered by which cause is the most common. I doubt it is tumors.Doc James (talk · contribs · email) 03:03, 1 December 2009 (UTC)

The Causes section has been reordered to better reflect the frequency of causes. The order currently stands at Migraines, Seizures, Drug use, Psychological factors, Epstein-Barr virus infection, Retinal edema, Macular degeneration, Central Serous Chorioretinopathy, and Brain lesions.
