Only iritis mucked up the scans. Out of the 24 people with the condition, five could not be identified by the scanners after treatment...Iritis affects about one in every 1000 people

So if only iritis inhibits the scan, and that in only 5 of every 24 cases, and only 1 in 1000 have iritis, then that just means a whopping 5 in every 24,000 people would require manual screening to determine identification. I don't see the problem here.

IMHO, the problem is false positives.
