I have no idea. Does it matter? These Coloboma are not as obvious as some seem to think.

"Carlos Anjos, chairman of the Portuguese Union of Police Detectives, said the publicity drive by Kate and Gerry McCann to find their four-year-old daughter had damaged the investigation and he called on them to stop."
"But Portuguese police, whose investigations usually operate in secret, always opposed the publicity and did not even want the child's photograph to be distributed.
Mr Anjos told Radio 4's Inside Stories programme: "We thought that the photos should not show the distinct mark Madeleine had in her eye.
"From our experience of criminal investigations, if this was a kidnap - which is what we believed from the start - the revealing of such a distinct feature would put that person's life in danger." end quote.
