The ANU has announced their work on pupillography (multifocal pupillography even).
Leaving aside the flashy iris it seems there’s much that can be gleaned from the pupil:
- Researchers at the ARC Vision Centre and The Australian National University led by Dr Ted Maddess and Dr Andrew James are pioneering the use of multifocal pupillography for accurate and painless detection and monitoring of diseases such as glaucoma, age-related macular degeneration and diabetic retinopathy. Together these are thought to affect around 100 million people globally, aged 50 and over.
The technique relies on a feedback loop of nerve signals, which flow from each eye to the brain and back again to both pupils of the eyes by a secondary pathway, Dr Maddess explains.
