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.[1] Strabismus surgery can be helpful in carefully selected patients if diplopia (double vision) occurs.[2]

Some individuals with a deficiency of coenzyme Q10 have CPEO as an associated abnormality. Coenzyme Q10 is important for normal mitochondrial function. In individuals with this deficiency, supplemental coenzyme Q10 has been found to improve general neurologic function and exercise tolerance. However, coenzyme Q10 has not been shown to improve the ophthalmoplegia or ptosis in people who have isolated CPEO.[3]
