First of all, I don't believe that there's a very good awareness about mefloquine in my profession. There are a number of neuro-optometrists who have worked with patients with mefloquine toxicity. I have a few cases, but in calling my colleagues in preparation for today, what I found is that the information is disappearing from the records. A lot of the people who we saw, we saw back in 2011 and 2012 in the U.S., and those records are being purged by doctors.
We have not done a good job of getting the visual consequences out into the literature. It's been not a small issue for the people who are involved, but it's a smallish issue in terms of the overall look at brain injury.
