Sienna has been diagnosed with Septo optic dysplasia which affects both her hormone production and her vision. Her optic nerves are undeveloped causing her to have little or no vision.
Although there is no treatment in the U.K. to restore her vision, clinics abroad offer a choice of 2 treatments to possibly give her some vision back and aid her growth/hormone problem.
Sienna’s family are desperately trying to raise £25,000 to fund the treatment in Thailand so Sienna can lead a normal life.
