Re: neuro ophthalmologist
Not only for kids, e.g. our hmo only has one for adults. Easier to find if you are near a major medical school or large city. But a really good ophthalmologist is ok.

If your shunt is not holding it's setting, do they check it every time you go into the emergency dept? Was it just checked? I would be ultra concerned if the shunt was not maintained at the intended settings. Do you work near magnets, headphones and phones have messed up some people. Anything you have close to your head with a possible magnetic field should be checked (think spouse told me there is an app to measure gauss) but otherwise has your implant been recalled or can it be considered defective?
