[Lower eyelid extension-plasty in patients with ptosis in chronic progressive external ophthalmoplegia].

Correction of ptosis in patients with chronic progressive ophthalmoplegia is problematic because the ptosis enlarges the palpebral fissure and aggravates the lagophthalmos. Additional lifting of the lower lids, which are often retracted, therefore seems advisable. Experience with various lower lid elongation techniques is reported.
