Fun with Eye Exams – Bright Lights, Big Migraine

December 7th, 2008

Last week I had an eye exam. It’s not something I had ever thought was a big deal. The purpose was to check the pressure in my eyes. A particular type of glaucoma can be a side effect of Topamax, the Migraine preventive medication I am on. In addition, there is a correlation between low-tension glaucoma and Migraine. I learned this about a month ago when I first went in for the eye exam, in the early stages of a Migraine, and asked to be taken out of the bright noisy waiting room. The optometrist scolded me a bit for never having told them (in seven years as a patient) that I had Migraines. My experience has been that most doctors know very little about Migraine, and it never occurred to me to share it with them. I didn’t know it was relevant.

That first visit was a very satisfying patient experience. My optometrist was sympathetic and clearly quite knowledgeable about Migraine; she also refused to dilate me and do the full exam while I had a Migraine. She did a partial exam and I was scheduled to come back in a week. There followed a month where I had a Migraine every Wednesday. It was a good month for me, because those were the only Migraines I had. But for some reason, they kept coming on Wednesdays, and I kept rescheduling the eye exam for the next Wednesday. Finally last week I got a Migraine on Tuesday evening. It was still hanging around, slightly improved, on Wednesday, but I decided I would not cancel the appointment a fourth time. I decided to go ahead with the exam, come hell or high water. I’m not sure whether you would call what followed hell or high water. Maybe both.

First we did a visual fields test. No big deal. Lots of little lights blinking on in my visual field, and I had to press a button when I saw them. Apparently I did well. No blind spots. Then she dilated me. And shined very bright lights in my eyes. Very very bright lights. And then brighter ones. And I had to look directly into the bright lights. That is not something I have done in a very long time. I have spent several years shying away from bright lights.

When I got home I spent the evening in a dim room, blurry eyed, in sunglasses. I tried to read, work on this blog, watch tv. My Migraine came back to life with a vengeance. And hung around another 24 hours, wringing me out like a wet rag. It took days for me to feel well again. So, no, I don’t recommend getting an eye exam with a Migraine. Problem is, if I hadn’t had a Migraine I’d say the chance is pretty high I would have gotten one. The good news is I don’t have any kind of glaucoma, and I was approved to increase my medication dosage. My eyes are in good shape. It’s my brain that’s a little iffy.
