Lady comes for eye test and finds she has a brain tumour We had a lady in just before Christmas for what she thought was a routine eye test.  It turned out that she'd lost her sight in her left eye as the blood supply to her optic nerve had been cut off.  We immediately referred her to the local hospital and followed up with phone calls to make sure the referral had been received and actioned.  The prognosis was not good for whatever was causing the issue - a stroke, MS, a tumour....until the scans were undertaken, we wouldn't know.
