Look into my eyes..
.. if this tech actually works, it should be generalized and encouraged. A non-invasive, presumably quick method of determining heart risks should become a yearly check-up procedure for everyone.
I just had my annual one done. A nice lady looked deep into my eyes, then flashed me. The joy of being T2 diabetic.
Procedure's reasonably quick, so a quick sight test with the traditional chart. Then the less fun part, so eye drops (she made me cry!) followed by a 20min wait for those to take effect. Then it's gazing into the camera, getting each eye shot a couple of times, then admiring my retinas on their screen. And discovering I could get a copy of the images, if I asked the screening department's booking desk. Praise the NHS!
Downside is it leaves your eyes rather dilated for a couple of hours, which isn't the most pleasent experience, or good if you're driving, using a screen etc. Especially as I'd forgotten my sunglasses and the Sun had decided to peek out. Plus there was a sheet listing potential side-effects from having your eye temporarily paralysed. Or just getting funny looks from having wild, staring eyes.
So I guess it'll boil down to how effective an expanded screening programme could be, or if the procedure could be simplified to use quicker/cheaper retina photography. No idea if it's something our increasingly smart phones could do, but retina scanning's getting more common as a security device. Or illusion of security, which is one of the reasons why I wanted copies of mine. Plus it's a part of my body I don't get to see every day.
Then it's praticalities, especially given the way GPs are overloaded and many people don't even get a regular annual check up. But I guess that could be automated. Simple call centre script to phone everyone. Are you alive? Press 1# for yes.
