Oftalmoplegia crônica é caracterizada por fraqueza progressiva de músculos oculares e do músculo elevador da pálpebra superior. A condição se manifesta principalmente em adultos. Pode ser um quadro total e permanentemente isolado, mas em uma minoria dos casos está associado a miopatia esquelética, que causa fatigabilidade anormal e até mesmo fraqueza muscular permanente.

Chronic ophthalmoplegia is characterised by progressive weakness of ocular muscles and levator muscle of the upper eyelid. The condition is mainly manifested in adults.
