An 46-year-old Italian man has pulled out his own eyeballs during a church mass.
He told doctors in Viareggio, Italy, he "heard voices" telling him to rip out his eyes. Dr Gino Barbacci said: "To do that requires superhuman strength."
Priest Lorenzo Tanganelli, who continued his service after the horror, said: "I've never seen so much blood."
Doctors were unable to save his sight.
