Extractions: Chronic progressive external ophthalmoplegia (CPEO) is a descriptive term for a heterogenous group of disorders characterized by chronic, progressive, bilateral, and usually symmetric ocular motility deficit and ptosis. Significant pain, proptosis, or pupil involvement are not features of CPEO and should prompt evaluation for alternative etiologies. Mitochondrial DNA mutations are increasingly being recognized as the etiology for CPEO syndromes. Clinicians should recognize the specific syndromes associated with CPEO, characterized by variable systemic, neurologic, or other findings. Treatment is limited, but newer therapies are being investigated.

Extractions: CPEO (Chronic Progressive External Ophthalmoplegia) is a condition of limited eye movements, but it is I think an entirely different entity from Congenital fibrosis. CPEO was often felt to be an isolated myopatchy of the extraocualr muscles. That has been some suggestions that CPEO has associated with it dysfunction of the mitochondria so there is some specuilation that mitochondrial DNA (mtDNA) might have something to do with the pathogenesis of this disorder. The majority of the cases of CPEO are sporadic. So, I am not aware of a connection betweeen congenital fibrosis and CPEO. Robert W. Enzenauer, MD, MPH
Extractions: These patients frequently present with ptosis, ophthalmoplegia and mitochondrial myopathy. Severe cases have onset before 20 years of age and also manifest retinitis pigmentosa and a least one of the following: cardiac conduction defects, cerebellar ataxia, or elevated CSF protein above 100 mg/dl. Approximately 83% of KSS and 47% of CPEO patients carry mitochondrial DNA rearrangements detectable by southern analysis. A great majority of these rearrangements are new mutations. Therefore, the patients are heteroplasmic for normal and rearranged mitochondrial DNA molecules. The remainder of cases result from a variety of point mutations. Since mutant mitochondrial DNA molecules may be undetectable in blood cells due to replicative segregation, analysis of muscle biopsy may be necessary if the blood sample is negative for rearrangements or mutations. Blood 5-10 ml whole blood in an EDTA ( purple top ) or ACD ( yellow top ) tube.

Wiedemann Mitochondrial myopathies are a group of disorders that can cause a variety of multisystem signs and symptoms, like hereditary oculopharyngeal dystrophy, cerebellar dysfunction, epilepsy or heart block. The most important ophthalmologic features of these disorders include ptosis, progressive external ophthalmoplegia and pigmentary retinal degeneration.

In addition, KSS may include cardiac conduction defects, cerebellar ataxia, and raised cerebrospinal fluid (CSF) protein levels (>100 mg/dL). Additional features associated with KSS may include myopathy, dystonia, endocrine abnormalities (eg, diabetes, growth retardation/short stature, hypoparathyroidism), bilateral sensorineural deafness, dementia, cataracts, and proximal renal tubular acidosis. Thus, KSS may affect many organ systems. Pathophysiology: KSS occurs secondary to deletions in mitochondrial DNA (mtDNA) that cause a particular phenotype. The gene in which deletions occur is identified as Online Mendelian Inheritance in Man number 530000. An understanding of some aspects of mitochondrial genetics is important to understanding KSS.

Patients usually experience bilateral, symmetrical, progressive ptosis, followed by ophthalmoparesis months to years later. Ciliary and iris muscles are not involved. CPEO is the most frequent manifestation of mitochondrial myopathies. CPEO in association with mutations in mitochondrial DNA (mtDNA) may occur in the absence of any other clinical sign, but usually it is associated with skeletal muscle weakness. Kearns-Sayre syndrome (KSS) is a related mitochondrial myopathy that demonstrates the following: CPEO, onset before age 20, and pigmentary retinopathy. KSS also has at least one of the following: cardiac conduction defects, cerebrospinal fluid (CSF), protein of greater than 100 mg/dL, and a cerebellar syndrome. Other abnormalities in KSS can include mental retardation, Babinski sign, hearing loss, seizures, short stature, delayed puberty, and various endocrine disorders. CPEO also can be a sign in the following disorders: oculopharyngeal dystrophy, myasthenia gravis, and Graves disease.

Extractions: David N Russell June 2000 Written by Dr D.Hilton-Jones, Consultant Neurologist, Oxford for the Muscular Dystrophy Campaign It has been recognised for many years that some patients with muscle disease have particular problems with the muscles around the eyes, although other parts of the body can also be involved. Whilst research is continuing, it appears that most of these patients have either oculopharyngeal muscular dystrophy (OPMD) or mitochondrial chronic progressive external ophthalmoplegia (CPEO). The main features of these disorders are discussed below. Some of the symptoms and signs are common to both disorders. Medical terms frequently used include: ptosis, external ophthalmoplegia, diplopia and dysphagia. Ptosis - this describes drooping of the eyelids due to weakness of the muscle that normally lifts up the eyelid. External ophthalmoplegia - this means weakness and restriction of muscle movement around the eye (external to the eye). It shows as slowness and incomplete range of movement of the eyes, and includes the eyelid muscle weakness that causes ptosis. These problems typically progress very slowly, hence the term 'chronic progressive external ophthalmoplegia'.
