Choroidal melanoma - currently have double vision and an enlarged pupil. How do others cope with this?

I was diagnosed last august and underwent plaque radiotherapy at hospital in October 2025 . The treatment is working but I have diplopia (double vision) and an enlarged pupil . I wonder how other people cope with this and wonder what they do to help .

i have had no professional advice and it seems I am left to get on with it  and cope as best as I can .
