....and the winner is.....macular edema, come on down!!
Scans revealed today that I do, indeed, have fluid bubbling up behind my eyes. Thankfully, since it was "caught" early, it can be treated (hopefully) with non-steroidal stuff. Because steroids are evil, vile drugs with ridiculously horrid side effects. So I have to be monitored every week now, but hallelujah! we have visible fluid, a treatment, and a course of action.
Now please excuse me while I go put eye drops in that will feel like burning ash has been shoved in my eyes.
