I was surfing the web to find a good project to make, using Deep Learning applied to the Medical Sciences and I saw a freshman that built an app that can reads the glucose levels only with a picture of the eye! See: https://www.youtube.com/watch?v=tl3fld7cxGA&t=1119s
I was intrigued by it and starting to search for scientific articles to find which part of the eye is responsible for "affecting" glucose levels' readings. To my surprise, I haven't found anything! Only a good application of neural networks to identify diabetic retinopathy, which makes sense by analysing pictures of the eye.
Does anyone have any knowledge to explain me how I can measure (or with what should my measures be based with) glucose levels with the eye? Or have any articles that provide such information?
