Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to determine whether changes in retinal vasculature seen on SS-OCTA can be correlated to degree of cardiovascular disease as measured by carotid duplex ultrasonography.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study's primary objective is to determine whether measures taken from SS-OCTA, color fundus photography, and retinal exams can correlate with and predict the presence/degree of carotid occlusive disease as determined by carotid duplex ultrasonography by examining the following parameters: retinal vessel caliber, retinal vessel density, retinal vessel perfusion, retinal vessel tortuosity, presence of Hollenhorst or other plaques, and/or areas of ischemia.

Intervention Type DIAGNOSTIC_TEST

The PLEX Elite 9000 is an FDA cleared research device for use in ocular imaging obtained by Northwestern University by way of a purchase agreement with the manufacturer, Carl Zeiss Meditec, Inc. It is currently unavailable outside of participation in the ARI Network, a cloudbased storage and image processing platform using deidentified information shared between academic institutions. The ARI Network is managed by a group of physicians and scientists from around the world that are working to better understand eye diseases.
