Talk:Metamorphopsia

Queen's University student editing initiative

Hello, we are a group of medical students editing this page as part of our class assignment. We have compiled a list of suggestions to improve this article and would appreciate community feedback before we proceed with these edits. Here is a list of our suggestions:

Thank you for your input and helping us improve the medical information available on Wikipedia! Hannram (talk) 22:08, 30 November 2020 (UTC)

1. Pathophysiology

We propose to create a section called Pathophysiology. Our proposed paragraph is as follows, in the pathophysiology section added below.

"The mechanisms that result in the development of metamorphopsia involve structural changes in the retina of the eye (retinal mechanism) as well as processing changes in the cerebral cortex of the brain (cortical mechanism). The retinal mechanism involves the displacement of retinal layers which results in the mislocation of light on the retina. The cortical mechanism, which was discovered after the retinal mechanism, is affected by perceptual “filling-in” and visual crowding effects. The cortical mechanism was found to work in combination with the retinal mechanism to contribute to metamorphopsia in long-standing maculopathy or after the treatment of macular disorders." Hannram (talk) 22:04, 30 November 2020 (UTC)

These both look like good secondary sources, meeting WP:MEDRS. Can you add wikilinks to any of these med terms (if they are not already linked earlier in the article)? Thanks for sharing this here. JenOttawa (talk) 16:14, 1 December 2020 (UTC)

2. Commons upload

We also propose to add an image of what a person experiencing metamorphopsia might see. The image and accompanying description can be found below. Isislunsky (talk) 18:59, 1 December 2020 (UTC)

Nice Wikipedia Commons upload! Did you draw this yourself? If the pages from the textbooks where you found this information are available, please include them in the citations. I added a "right" to your image (versus middle), it may take some fiddling to get the image in the correct place in the article. Great work so far.JenOttawa (talk) 19:31, 1 December 2020 (UTC)

@Isislunsky: if you want to try to add your commons image before class, you are welcome, just to ensure there is time for troubleshooting. You can "preview" your edit to check on placement/size (by clicking publish changes once, it gives you an option to preview and add an edit description. You can then go back and tweak before clicking "publish" a second time. If you look at a few other higher-quality Wikipedia articles you can check that your image placement and size looks on par. If you do publish it but want to tweak after, you can click "edit" and go right back in and tweak. If you have any questions please do reach out!JenOttawa (talk) 17:06, 7 December 2020 (UTC)

Thank you so much for the feedback (and I did draw the image myself)! I took this and physician feedback and made the appropriate changes. Isislunsky (talk) 20:02, 7 December 2020 (UTC)

3. Causes

We proposed to create a new section entitled "Causes of Metamorphopsia". Our proposed addition to this new section is as follows:

"Metamorphopsia can be a symptom of a number of eye disorders involving the retina or macula. Some of these conditions include the following:

• Age-Related Macular Degeneration
• Epiretinal Membrane and Vitreomacular Traction
• Posterior Vitreous Detachment
• Macular Hole"

Thanks for sharing this. Please note that citations go immediately after the punctuation. Nice use of Wikilinks!JenOttawa (talk) 03:56, 5 December 2020 (UTC)

4. Diagnosis

We also propose to create a section called Diagnosis. Our proposed addition to this new section is as follows:

"Current tests used for diagnosis of Metamorphopsia mostly make use of subjective assessments of how a person views regular patterns, making such tests have poor sensitivities. More recent assessments are making use of a psychophysical test called preferential hyperacuity perimetry, which assesses a person’s ability to any misalignments of visual objects for a more sensitive diagnosis of Metamorphopsia." --Peanutoats (talk) 19:13, 2 December 2020 (UTC)

The use of the word "current" is confusing for Wikipedia as it is not clear when it was written. You can add in a date here or just say "Tests used for diagnosis of Metamorphopsia..."JenOttawa (talk) 03:56, 5 December 2020 (UTC)

Note: Multiple use of the same reference- tech tip. When you add your references while editing, you can see the options "automatic... Manual... Re-use". The first time you add the citation (if it is not already used in an article, click "automatic" and add your PMID, DOI, or website, then click "generate" to fill the template. The second time you want to use the same citation in an article, click "reusue" and search for your citation in the list. This adds in the a,b,c versus duplicating the citation in the list. If possible, practice this in your sandbox before editing live on Monday. JenOttawa (talk) 04:01, 5 December 2020 (UTC)

5. Treatment and prognosis

We also propose to create a section called "Treatment and Prognosis". Our proposed addition to this new section can be seen below:CARLegends (talk) 02:20, 3 December 2020 (UTC)

"Metamorphopsia is a symptom of several common retinal and macular diseases, therefore treating the underlying disorder can improve symptoms. In individuals with Epiretinal membrane (ERM), Macular Holes and Retinal Detachment, decreased metamorphopsia is associated with an increase in visual acuity. " Quantitative evaluation of metamorphopsia is an important step in understanding visual functions of individuals with macular disorders and is an essential tool for physicians in evaluating treatment results. " CARLegends (talk) 23:35, 4 December 2020 (UTC)

Nice Wikilinks. Please note that when you are editing in the actual article, citations go immediately after the punctuation (not before). Can you add a few more wikilinks- quantitative, for example. Thanks for sharing this. JenOttawa (talk) 03:56, 5 December 2020 (UTC)

6. Background info

We also propose to expand upon the background information provided on the Wikipedia page. Our proposed changes include:

Initially characterized in the 1800’s, Metamorphopsia was described as one of the primary and most notable indications of myopic and senile maculopathies.</ref Midena, E., & Vujosevic, S. (2016). Metamorphopsia: an overlooked visual symptom. Ophthalmic research, 55(1), 26-36.> Metamorphopsia can present itself as unbalanced vision, resulting from small unintentional movements of the eye as it tries to stabilize the field of vision.</ref> <ref 1Midena, E., & Vujosevic, S. (2016). Metamorphopsia: an overlooked visual symptom. Ophthalmic research, 55(1), 26-36.> Metamorphopsia can also lead to the misrepresentation of an object’s size or shape.</ref River, Y., Hur, T. B., & Steiner, I. (1998). Reversal of vision metamorphopsia: clinical and anatomical characteristics.

Thanks for sharing this. When you add your reference please ensure that you are using the tool correctly so your reference is in the correct format. This is in the lecture notes from our Wiki skills session. You can paste the PMID or DOI and then click "generate" to add it wiki-style! If you have any problems please let me know. If is a good idea to practice this in your sandbox as well.JenOttawa (talk) 04:03, 5 December 2020 (UTC)

Types

types are incorrect, they refer to macular degeneration not metamorphopsia. Should be removed. Michalpro (talk) 20:32, 15 March 2023 (UTC)
