More broadly, as tools advance and catch signals to notify of certain irregularities, this may be of interest:

"Jan Egger and Jens Kleesiek, medical researchers at Essen University Hospital in Germany, are looking at ways in which the headset might be useful for health care2. They say that the Vision Pro’s advanced eye-tracking technology might be capable of picking up conditions such as vertigo, or even early signs of a stroke or dementia. The pair plan to study this when they get one of the headsets. “You have different eye movements and these can be detected using such a device,” says Kleesiek. “The quality of the sensor readings is so high that you can actually utilize it for such medical tasks.""
