tried stem cells in two different way's , is there any thing else i can do ?

Brief Summary:
The patient was in her usual good state of health when she awoke on 22 February 2008 with headache, blurry vision, and shortness of breath. This was preceded by consuming alcohol provided from an unknown source. The patient then went to a local hospital, and developed a seizure on her way. Blood tests revealed a severe metabolic acidosis with a PH of 6.76. She was reportedly comatose for 24 hours. When she awoke, she was unable to see.
Diagnosis and treatments history:
Briefly, the initial impression of the patient's case suggested that the patient was suffering from methanol poisoning. Subsequently, she was transferred for treatment to Amman, Jordan. Here, the patient received a course of stimulating steroids, but she showed no improvement.
Following her stay in Jordan the patient was referred to Mayo Clinic, Minnesota, U.S.A. Doctors at the Clinic examined her case and determined that she is suffering from optic atrophy and bilateral occipital lobe damage; they concluded that there weren't any modalities that would be helpful in promoting a return of vision.
About a year later, the patient travelled to China, Nanjing where she received six stem cells injections, tow into her bone marrow and four into her veins, intended to enhance the growth of her optic nerves. However, this treatment wasn't fruitful because of several potential reasons, most important of which is that the stem cells were not extracted from the patient; hence, her body could have rejected them. She hasn't shown any reaction that suggests a rejection though.
a year after, the patient is back in Jordan. She has received two stem cells injections feeding directly into the optic nerves. The cells were extracted from her body. Although she hasn't experienced any improvements, doctors were very optimistic.But nothing change ?
is there any hope ? any treatment? even if it's Little we will go for it.
the patient's Son.
