Noticeable patient findings included: overall visual function improvements by all eight patients within sixty (60) days of treatment; reduction in absolute scotomas; increases in the thickness of the optic nerve fiber; resorption of hemorrhages; no new micro bleeding edema of the nerve fiber layer; and, a decrease in macular edema. Improvement in the function of different layers of the retina and optic nerve were experienced as well as a reduction in the number of scotomas in the field of vision. None of the patients developed tumors, had impaired vision or experienced adverse health effects connected with the cell injections, and seven of the eight participating patients have maintained the overall vision improvements they gained from treatment three years later.
