Interesting you mention that. The last time I had my eyes checked, the optometrist asked me if I had HBP. I don't, but the discussion ensued, he looked again, and advised me I have an anomaly that looks like the result of HBP. He's seen it before, and it's not a problem - just a coincidence - but now when neurologists, etc. take a peak and pause, I know why and there's a short discussion about the anomaly. (shrug)
