The good news is that my retinas are okay. The bad news? None really; my vision is stable for the second year in a row and my eyes are fine. I'll call that a win in just about any playbook.

I had a scary incident a few weeks ago. The vision in the central portion of my right eye blurred and began to do what I can only describe as 'sparkle.' There was no pain and no other change, just an area the shape of a crescent moon in my central field of vision that was strangely prismatic.

It went away that same afternoon. Geof was right to question my blood pressure -- low as usual -- and there were no side effects.

I was glad to confirm that all was well. Ever since my mother had her cornea transplant thanks to Fuchs' dystrophy, I've been more aware than usual of how fragile my sense of sight is, and how lost I would be without it.
