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: 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.

Extractions: Clin Cardiol. 1997 Mar; 20(3): 239-243. The cardiac function in five patients with chronic progressive external ophthalmoplegia (CPEO) was evaluated. Carotid pulse recording and echocardiography showed a left ventricular systolic dysfunction in two patients. One of these patients died of congestive heart failure 2 months after the study. The Doppler pattern of left ventricular filling in the three remaining patients showed left ventricular diastolic dysfunction. Although the cardiac involvement of patients with CPEO is generally considered to be limited to the cardiac conduction system, left ventricular dysfunction should receive more attention in the management of patients with CPEO.

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.

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.

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 subjects (16 eyes) were measured digitally. Images consisted of 1.5-mm contiguous sections acquired using a volume (three-dimensional) gradient-echo acquisition. In all, measurements were
