[NOTE: I’ve decided to write an explanatory piece about my recent eye problems and surgery. It may be long and boring to some, but I think it might be helpful if anyone is going through a similarly confusing time with the medical profession. This is the first of several planned parts.]
I had good vision as a child and young adult, and it persisted through much of my life. I wore distance glasses for only two things: to see subtitles in the movies, and to drive at night. And I didn’t even really need them for either of those tasks, although they helped. I could also usually make do without reading glasses except for small print in low light.
But about twenty years ago I went for my annual visit to the eye doctor and as the technician was looking at my eyes he suddenly said, “Excuse me; I’ll be back in a few minutes.” I had no idea what was going on, but his abrupt departure made me uneasy.
He returned ten or fifteen minutes later with the eye doctor, who peered into my eyes for a while with some instruments, and then told me I would need laser surgery for something called “narrow angles.” My eye structure was such that the drainage system was now potentially compromised, something that happened more commonly in Asian people. I’m not Asian, but I had it anyway, and he told me that meant I could suddenly go blind in a matter of hours after getting the first symptoms, which would be eye pain. It could happen any time, any place, and I had to be near a hospital because I would need emergency surgery in the event of an attack of what’s known as narrow angle glaucoma (not to be confused with the more common sort of glaucoma, which is a different thing with a different cause).
He said that the laser surgery would be very simple, so simple that it really didn’t qualify as “surgery.” It was done in the office and took a minute or two. The procedure was called an iridotomy, with the laser putting a small hole in the patient’s iris so that the fluid would drain if there was an attack and the pressure would never build to damaging proportions. Complications were so rare as to be nonexistent. In one in a million people, the tiny hole in the iris let in light that the retina could perceive as an extra little gleam in the visual field. But that just about never happened.
The whole thing scared me, and I wanted to wait a while and think about it. If I waited, he said, I would have to avoid having my eyes dilated. That could precipitate an attack. I would have to avoid suddenly going into a very dark room – that could precipitate an attack. I would have to avoid taking the following medications – and he proceeded to hand me a very long list.
It was sobering, even though I felt like a wimp for being afraid. My vision was so good that it was hard to accept that I needed eye surgery, even a minor one. But after a year or so and a consultation with another eye doctor who told me I had very narrow angles and really needed the surgery, I decided to do it. The doctor wanted to do both eyes at once, but I insisted on one at a time.
The day came, and the surgery was an odd experience but not such a terrible one. They lasered my left eye first. Afterwards my vision was unclear because they put some sort of sticky substance into the eye, but after a few hours it cleared.
Except for the new light in my eye.
My iridotomy hole was at two o’clock in my vision and the light was at eight o’clock, reflecting the flipping of images by the retina. I was panicked and distressed, and went back to the doctor who had done the iridotomy. He was almost as upset as I was; maybe even more so. He said it was the first time this had ever happened in an iridotomy he’d done. He also said that my iridotomy opening was very large because when he used the laser my iris “split like a broken zipper.” Ugh. He told me, though, that over time the brain adjusts and the extra light becomes much less disturbing.
And that’s what happened. After a few months, I often didn’t even notice it, although at times it became quite annoying again depending on light conditions. But now I faced having the other eye done. This time I went to a fancy eye clinic in Boston, and the doctor used a different technique for the iridotomy on the right eye. Fortunately, no broken zipper and no extra light in that eye.
And that’s the way it remained for many years.
