Dear friend, welcome to HCM.
I think a good neurologist
is the right person to seek help from.
but such old palsy
may remain such. it may be helped by some protective surgeries like tarsorrhapy.
pl. consult an ophthalmologist about eye protection from corneal ulcerationsdue to open eye.
I hope to have guided you in right direction. revert back with any queries, I would like to help.
take care and keep me posted on your progress.
good luck !
