Metamorphopsia

Assignment # 3

 * 1.       Proposed Changes My proposed change is to add a “Pathophysiology” section to our Wikipedia article that briefly explains the pathologies related to metamorphopsia: 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.1 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.2
 * 2.       Rationale for Proposed Change I used the following references to support the above content. As there is no explanation of pathophysiology on the site currently, we thought this may be of interest to readers either experiencing or researching metamorphopsia. The first three sentences pertain to reference 1 and describe the two mechanisms by which metamorphopsia pathogenesis occurs. Reference 2 supplements information about the cortical mechanism, as there was insufficient information to explain this clearly in reference 1. I tried to explain these concepts in an accessible way to give layman readers a general overview. The sources, which are reliable secondary sources and meet Wikipedia standards, can be accessed for more detailed and high-level information.  (1) Chen Q, Liu ZX. Idiopathic Macular Hole: A Comprehensive Review of Its Pathogenesis and of  Advanced Studies on Metamorphopsia. J Ophthalmol. 2019 May 23;2019:7294952. doi:  10.1155/2019/7294952. PMID: 31240135; PMCID: PMC6556255.  (2) Midena E, Vujosevic: Metamorphopsia: An Overlooked Visual Symptom. Ophthalmic Res 2016;55:26-36. doi: 10.1159/000441033
 * 3.       Area of Controversy Currently, there is no controversy about these changes as this is a new addition to the site. The mechanisms of pathophysiology described are well agreed upon by the reviews I accessed, as well as by the sources cited within these articles.
 * 4.       Critique of Source Neither of the review articles that I cited included the criteria they used to search for the studies that they chose to include in the review. Depending on how this was done and how extensively, this could lead to publication bias if less statistically significant studies were not included. However, these reviews are both secondary sources that come from reliable and peer-reviewed scientific journals. These sources also use up to date evidence and were both published in the last 5 years.
 * 5.       Article Improvement My proposed improvements and references have been shared on the metamorphopsia talk page.

What to post on the Wikipedia article talk page?

 * This will also be covered on Nov 23rd in class. Your group should use the below template to share an outline of your proposed improvements (including your new wording and citations). Article talk pages are not places to share your assignment answers. The Wikipedia community will be more interested in viewing your exact article improvement suggestions including where you plan to improve the article (which section), what wording you suggest, and the exact citation (Note: all citations must meet WP:MEDRS)
 * You will not be able to paste citations directly from your sandbox to talk pages (unless you are interested in editing/learning Wiki-code in the "source editing" mode). We suggest re-adding your citations on the talk page manually (using the cite button and populating the citation by pasting in the DOI, website, or PMID). You will have to repeat this process yet again when you edit the actual article live.
