Definitions of Progressive external ophthalmoplegia:

A mitochondrial myopathy characterized by slowly progressive paralysis of the levator palpebrae, orbicularis oculi, and extraocular muscles. Ragged-red fibers and atrophy are found on muscle biopsy. Familial and sporadic forms may occur. Disease onset is usually in the first or second decade of life, and the illness slowly progresses until usually all ocular motility is lost. (From Adams et al., Principles of Neurology, 6th ed, p1422) - (Source - Diseases Database)

Ophanet, a consortium of European partners, currently defines a condition rare when it affects 1 person per 2,000. They list Progressive external ophthalmoplegia as a "rare disease".
