Now Picture This on an Eyeball

I've got this horrible mental picture...

A case reported in a recent issue of the journal Emergency Medicine Australia described the successful removal of a leech from an eyeball. A 66-year-old woman, gardening in her back yard in Sydney, had accidentally flicked some soil into her eye. By the time a surgeon could extract the leech, it had roughly tripled its body size by feeding on the eyeball's blood vessels.
