I did mean cataracts. We usually do OCTs of the anterior segment (cornea to lens; uses a different wavelength for imaging) to plan lens surgery and measure keratoconus (among other things) but as a side effect, even in seamingly healthy eyes you can measure how optically dense different parts of the lens are to predict when cataracts are going to form. It’s hard to do by just looking at the OCT image because the way the lens looks depends on many factors but there have been some interesting AI-based approaches popping up lately.
But sure, with a posterior segment OCT, you can detect all the things you mentioned.
I’m not in the industry any more but when you said grading I stupidly thought you meant like what I was doing monitoring diabetic retinopathy OCT scans.

Wow sorry I stand corrected. That’s very cool!
