Tara Moore and her husband Consultant Ophthalmologist Professor Johnny Moore are heading up the Amazon River on a charitable expedition with the Andean Medical Mission; a UK charity within the Bolivian Andes and Amazon. Johnny will lead a surgical unit carrying out sight saving eye surgery on people who are unable to access Ophthalmologists. While in Bolivia, they will also be investigating the genetics of Pterygium; an overgrowth of tissue in the eye, which can affect vision. Along with geneticist Andrew Nesbit, they will compare the occurrence of Pterygium in Bolivia with cases found in Northern Ireland patients.
