Its a very rigorously done report and the first demonstration of this in someone with apparent total absence of a striate cortex, the visual processing region, said Dr. Richard Held, an emeritus professor of cognitive and brain science at the Massachusetts Institute of Technology, who with Ernst Poeppel and Douglas Frost wrote the first published account of blindsight in a person, in 1973.
