Chronic Progressive External Ophthalmoplegia: A Case Report.

Chronic progressive external ophthalmoplegia (CPEO) is a rare mitochondrial disorder characterized by bilateral, slowly progressive ptosis and paralysis of the extraocular muscles. We present the case of a 61-year-old female with a 36-year history of bilateral ptosis and limited eye movements without diplopia. No family history of CPEO or other mitochondrial disorders was reported. To the best of our knowledge, this is the first documented case of CPEO in Trinidad and Tobago.
