Some of are no doubt wondering if this post's title is a ploy to get a Jackson Browne song into Campanastan.
Yes, it is.
Seriously, about a month ago I posted about my difficulty in reading (and writing blog posts) caused by a condition known as retinal vein occlusion (RVO) and consequent macular edema (swelling of the macula, the central part of the retina that is responsible for detail vision), in my right eye. As befits a hydrogeologist, I have fluid leakage that is causing the swelling.
Many of you have wished me well (thanks!) so I just wanted to give you an update.
My ophthalmologist,Dr. Gary Servais, has been injecting my retina with Avastin, a cancer drug that is also effective at relieving retinal swelling. After the first injection the corrected (I wear prescription lenses) vision in my right eye went from 20-60 to 20-40. That improvement was quite significant, and the swelling had subsided dramatically. That has not really translated into greatly-improved detail vision, for reasons that I don't need to explain, but my detail vision is somewhat better. As Dr. Servais said, if the swelling keeps subsiding, my detail vision will return quite dramatically, just as it departed (literally overnight).
Upshot: I received a second Avastin injection and am scheduled for a another one in a few weeks. This condition apparently cannot be cured, just managed, so should the treatment work I will need to get injections at some as-yet undetermined frequency for the rest of my life. I'll gladly take that. The odd thing is that RVO is usually associated with hypertension and diabetes, neither of which I have.
Regarding the fluid flow aspects: as part of my testing I underwent fluorescein angiography, where I was injected with fluorescein dye, whose circulation in the retina was observed to assess blockages. Pretty neat stuff; the images looked like a fracture-flow network. I explained to the medical staff that I had used the same dye for water tracing. They were quite amazed when I explained why I did it and what it told me.
Okay, enough of the medical report. The usual stuff will return shortly.
Thanks for your indulgence.
