South African veterinary surgeon Pizzi carried out a keyhole surgery on Champa, a three year old bear who lives at a sanctuary in the mountains of northern Laos.
The vets and staff and Free the Bears sanctuary were troubled by the erratic behavior shown by Champa and suspected that she was suffering from hydrocephalus, a condition similar to having a 'constant migraine'.
Pizzi, who works at Edinburgh Zoo in Scotland, carried out the six-hour long surgery in February. Speaking to National geographic, the chief executive of Free the Bears, Matt Hunt said that Champa's condition has improved following the surgery. "There was a lot more recognition. We can't know if her vision is fully recovered, but everyone certainly believes her vision has improved", he said.
