What is Chronic Progressive External Ophthalmoplegia (CPEO)?
Chronic Progressive External Ophthalmoplegia (CPEO) is a mitochondrial myopathy characterized by the gradual paralysis of the extraocular muscles. This leads to ptosis (drooping eyelids) and ophthalmoplegia (weakness or paralysis of the eye muscles), affecting the patient's ability to move their eyes and maintain proper ocular alignment.
