Pardon me if I've said this before, but I'm still not seeing anyone else drawing this conclusion.
Turn a blind eye?
Turn the other cheek?
Both might be apt, after all.
Japanese researchers report in this week's New England Journal of Medicine that they have successfully transplanted thin layers of cheek cells onto the eyes of four blind patients with a rare and painful eye condition causing clouding of the cornea, restoring their sight.
The new corneas were still clear 14 months later.
They took 3-millimeter-wide squares of tissue from inside the patients' cheeks and used a low-temperature technique to grow them into thin layers in the lab.
The new cell layers stuck to the eye without stitching and, within one week, developed into tissue that looked and acted like healthy corneas.
