I have a new patient. She is a 53 year old female with blurry vision and floaters in her right eye only. She has seen several opthalmologists and had an MRI of brain. She is perfect. They are stumped. Her tongue is pale but slightly purple normal coating. Her pulse is wiry. I think because of the floaters it is blood deficiency with some stagnation. She started Si wu tang. Today is her third treatment over 3 weeks....her schedule is busy. She is a healthy eater. I'm stumped. Any suggestions? Thanks
