Ultrastructural analysis of extraocular muscle in chronic progressive external ophthalmoplegia.
Extraocular muscles are primarily involved in many mitochondrial diseases, but no reports exist regarding the morphological appearance of the muscles in cases of long-standing ocular myopathies. For this reason, muscle samples obtained from surgery in a sporadic case of chronic progressive external ophthalmoplegia (CPEO) were used for ultrastructural investigation and molecular analysis of mito...
متن کاملMR of extraocular muscles in chronic progressive external ophthalmoplegia.
PURPOSE Our goal was to determine whether the extraocular muscles in patients with chronic progressive external ophthalmoplegia (CPEO) could be distinguished from those of age-matched control subjects by MR imaging. METHODS Nine patients with CPEO and eight age-matched healthy control subjects were studied. The extraocular muscles of eight of the patients (16 eyes) and all the control subject...
متن کاملExtraocular Muscle Atrophy and Central Nervous System Involvement in Chronic Progressive External Ophthalmoplegia
BACKGROUND Chronic progressive external ophthalmoplegia (CPEO) is a classical mitochondrial ocular disorder characterised by bilateral progressive ptosis and ophthalmoplegia. These ocular features can develop either in isolation or in association with other prominent neurological deficits (CPEO+). Molecularly, CPEO can be classified into two distinct genetic subgroups depending on whether patie...

متن کاملCardiac abnormalities in chronic progressive external ophthalmoplegia.
This report describes heart disease in a 32-year-old man with the syndrome of chronic progressive external ophthalmoplegia (CPEO). The surface electrocardiogram showed first degree AV block and left bundle-branch block and there was HV prolongation on the His bundle electrogram. Endomyocardial biopsy showed the changes of hypertrophy on light microscopy, and on electron microscopy there were in...
