 Wikipedia Assignment 3 

Proposed Changes

Recently, two new non-invasive imaging techniques have emerged that aid in the diagnosis of central retinal artery occlusion: Optical Coherence Tomography (OCT) and Optical Coherence Tomography Angiography (OCTA). Patients may have anatomic differences in the different layers or blood vessels of the eye, which can be visualized with these imaging techniques.

Rationale for Proposed Change

The current Wikipedia article on CRAO does not include a section on the diagnosis of the disease. The above changes were proposed to provide some information regarding two new imaging techniques that can be used in the diagnosis of CRAO, and the two sources chosen are review articles describing the new technologies and the different findings that can be visualized with these techniques.

There may be some varied opinion regarding the utility of the two new techniques, since the older techniques (fundoscopy/angiography) have been successfully employed in the past. However, the new techniques have good utility and are non-invasive, and the article by de Carlo et al. (2015) states some clear advantages of the new techniques in comparison to the old ones.

Critique of Source

The case series by Kapoor et al. (2015) may be potentially impacted by selection bias. The review article speaks about the utility of OCT in the diagnosis of CRAO and uses five case reports of patients to illustrate their findings. However, since the authors want to demonstrate the effectiveness of OCT in CRAO diagnosis, there may have been bias in selecting only case reports where there were different anatomic findings that could be clearly visualized with OCT. This has not impacted my plans for this information because the five studies included still demonstrate distinct anatomic differences in CRAO patients, along with citations to other studies that have similar findings.
