We are developing a new, affordable imaging tool to detect changes in small vessels to detect early signs of cardiovascular disease. It clips onto the ear, which has advantages over current methods which image small vessels in the retina. First, the ear is accessible on both sides and relatively thin, enabling the use of light transmission imaging methods. Secondly, the ear can withstand much brighter light exposure, increasing the signal to noise ratio. Due to its low cost, non-invasiveness, portability, and focus on small vessels (which show the earliest signs of disease), it could be used in routine clinical visits as well as preventative screening in high-risk populations.
The objective of this study is to assess if this device can measure small vessel diameter accurately by comparing it with retinal imaging.
