Eye Proptosis - in Humans

In Humans

Although human eye proptosis or luxation is uncommon, both women and men have attempted the Guinness World Record for "eye-popping". Eye luxation is therefore not unique to dogs and can be acquired from natural causes at birth, rather than from head trauma. Proptosis is also seen in association with Graves' Disease, a form of hyperthyroidism. Proptosis can also be a sign of an ultra-rare disorder called Erdheim-Chester Disease.

Although Cláudio Paulo Pinto, who is the Brazilian record holder for eye-popping, can "pop" his out 7 millimetres (0.28 in), the current world record holder is Kim Goodman of Chicago who can extend her globes 12 millimetres (0.47 in) out of her sockets.
