We describe the surgical approach of two patients with myogenic blepharoptosis. The ptosis is caused by a glycogenosis type II (Pompe disease) in the first case and is due to a juvenile, chronic progressive external ophthalmoplegia (Kearns-Sayre syndrome) in the second case. The first patient presented a unilateral ptosis. The ptosis in the second patient was bilateral and manifest. The eyelids could only be opened manually. A resection of the palpebral levator muscle was carried out under local anesthesia. The choice of the technique will be explained. The amount of levator resection was calculated considering the residual eyelid motility and Bell's phenomenon. Electronmicroscopy of the resected levator muscle will be discussed.
