Thanks for the feedback; given the episode based nature of this, and the
length of time involved, I had also been suspicious that it may be MS.

The only puzzling thing has been that there has been absolutely no pain,
and both eyes have been affected at the same time, something that
appears to be unusual (based on the literature that I have read) for MS.

I will ask about testing for MS at my next consultation.

Thanks,

Mike.
