Just a quick update: I went back for my follow-up pressure test and the pressure in my eyes was asymmetric, with the right eye being significantly higher than the left eye. The optician wrote to my GP, and my GP advised me to come off Topiramate, which I'm in the process of doing. It's not the sort of stuff that you can just quit without potential repercussions. I went down from 2-a-day to 1-a-day for 2 weeks and now I'm on one every other day for 2 weeks, after which I quit completely.

The sunburst is still with me, but is less obtrusive as the drug is withdrawn.

The GP has referred me to an opthalmologist, where I've been classified as routine and given an appointment in August.

However, this whole thing has got me quite rattled, as I have other vision problems associated with migraine which are not an aura and I may attend A&E at the local hospital with the eye facilities next time the sight in my left eye drops off from being able to read most of the bottom line of the eye chart to struggling to read the letter at the very top. My GP has known about this problem for a couple of years and has theorised about what it is, but if there's a possibility that it's glaucoma related, I'd like something a bit better than theories and intend to go to A&E next time I have the problem.

So as the sunburst is getting less obtrusive as the drug is withdrawn, my monitors can probably stay as they are. I have changed the background colour in Windows from white to a pale green, which I think helps somewhat as well.

I haven't done much image editing recently due to a shortage of hard drive space, but we've finally found a USB enclosure that actually works with a 500GB IDE hard drive, so I've now got plenty of hard drive space again, and if I can find the time, I might sit in front of my computer and edit some pictures. I've got plenty waiting to be done!
