    ### Response:
    How might chronic progressive external ophthalmoplegia be treated? Ptosis caused by chronic progressive external ophthalmoplegia (CPEO) can be corrected by surgery, or by using glasses that have a ptosis crutch to lift the upper eyelids. Strabismus surgery can be helpful in carefully selected patients if diplopia (double vision) occurs.
