Field Cuts

My mother suffers a RT field cut in both eyes (from brain tumor result of breast cancer). In July she fell and hit her head which an MRI showed a bruise but not near the optical area. However  since then she has not been able to read; everything is blurred and is mixed up.  One doctor feels the field cut plays a big part (which we understand) however before the fall she could read.  Please any help would be appreciated.

There are many causes: the field cut, the brain tumor, internal eye disease, general dibility. See an eye MD ophthalmolgist to work through the causes perhaps an neuroophthalmologist.
