j l c paul,
Is your daughter's vision still blurry? Was it blurry before she started taking Topamax? If vision problems arise as a possible side effect of Topamax, it is extremely important to talk to the doctor who prescribed it. Topamax has some potentially serious and permanent visual side effects. You can read more about this in Potential Vision Issues with Topamax.
A single Migraine that lasts 72 hours or longer with less than a solid four-hour pain-free period, while awake, is termed status Migrainous. You should see your doctor or go to the emergency room if a Migraine lasts that long. See Status Migrainous - The Basics for more information.
At this point, as you know, stopping this Migraine needs to be a priority. When oral medications have failed, IV infusions will often break the cycle. For more information about this, see IV Treatment of Refractory Migraines.
Do you know what any of her triggers are? When working to identify triggers one of the best tools is a good Migraine diary. You can read more about this and download a free diary workbook in our article Your Migraine and Headache Diary.
Above all, don't lose hope! There are now over 100 medications and supplements that can be used for Migraine and headache prevention. The frustration of trying to find what works for us can make it seem as if we've tried it all, but with so many possible preventives, it's literally impossible to have tried them all. See Migraine preventive medications - too many options to give up! for more information.
If your daughter's doctor isn't able to help you, it may well be time to consult a Migraine and headache specialist. It's important to note that neurologists aren't necessarily Migraine and headache specialists. Take a look at the article Migraine and Headache Specialists - What's So Special? If you need help finding a Migraine specialist, check our listing of Patient Recommended Migraine and Headache Specialists.

I really feel for you. My Migraines started when I was six. One of our granddaughters had her first one at two and a half. It's hell to watch our little angels go through this.
Hope this helps,
