Article Synopsis
- Delays in healthcare processes can lead to serious health issues, highlighting the need for better understanding of current processes through flowcharts generated from real-world data.
- This study analyzed physician insurance claims and hospital data for patients who had carotid endarterectomy, aiming to find the reasons behind treatment delays between 2008 and 2014.

Methods: We performed a retrospective review of consecutive patients presenting with retinal ischemia who subsequently underwent carotid intervention from January 2018 to December 2022. Patients were classified into three groups (group I: amaurosis fugax/vascular transient monocular vision loss, group II: ocular ischemic syndrome [OIS], and group III: central/branch retinal artery occlusion).
