difference of changes to light in each pupil

Recently I was noticed by a doctor when having neuro observations done that my pupils had unequal changes to them when the light was was shinig in them by him Could you tell me what causes this. I do have MSA  but this is the first time this has shown up since being diagnosed in 2006. I ope you can help me with this as I am very  worried about it. No seeing my neurologist for another six weeks.

Could have many causes from nothing at all to something significant.  You need to see an ophthalmologist to do a multi-step test and exam that likely will involve different drops to see what is causing this difference.  A neuro-ophthalmologist would be best but any above average ophthalmologist should also be able to perform the required tests to figure out why.
