Our story thus far ...
Well, the optometrist shipped me back to the primary care physician, who on Thursday (3 March) took one look at my previous regular blood sugar tests and expressed complete disbelief I could have diabetes.
(Hey kids, there is a reason to see a doctor on regular basis -- a well kept medical history is your friend.)
She ordered up the usual fasting profile (including blood sugar) anyway, upped the blood pressure medications, and shipped me off to the ophthalmologist.
Friday, the ophthalmologist dilated my eyes (again), took a look, and said that yup, I have minor hemorrhaging. Most likely it's caused by the high blood pressure. I am to give it four weeks, and then see a retina specialist across town.
