So I've been a little remiss in keeping y'all updated on what's happening with my eyes. For those that missed this earlier, my optometrist was thinking I had a condition called pellucid marginal degeneration (PMD). Further investigation revealed, however, that what I have is actually its somewhat-more-common cousin, keratoconus [LINK WARNING: pictures of strange-looking eyes]. Both PMD and keratoconus are conditions in which part of your cornea gradually loses thickness over time.
Longer term, I'll need to wear rigid contact lenses for the rest of my life. I have glasses now, and they help a lot, but they can't fix the starbursts/halos I see with bright lights at night. And for someone who likes to drive (especially at night), that's a big problem.
For now, though, I don't get to even consider contact lenses until my vision settles down (likely between June and September). And in the meantime, I'm going to have to be particularly careful at night. But at least I have a path forward, and a lot more certainty about what to do next, and what to do if it looks like the experimental treatment didn't work.
