Precision Study of CLAiR AI Software
Completed · Not applicable
Conditions studied: Cardiovascular Risk
In brief
This multi-site precision study evaluated the performance and reproducibility of the CLAiR artificial intelligence (AI) software in identifying elevated risk of atherosclerotic cardiovascular disease (ASCVD) from retinal fundus images. Participants underwent protocol-defined retinal imaging using Topcon NW400 and NW500 cameras. The study assessed agreement and consistency of device outputs across operators and imaging conditions. No medical management decisions were made based on device results.
