Resumen

Background: Cerebral ptosis is understood as the bilateral paralysis of eyelid elevation linked to a stroke or hemorrhage of the middle cerebral artery (MCA). It is a transient condition, independent of the evolution of the lesion. Aim: To analyze six patients with the condition. Patients and methods: Report of five women and one male aged 42 to 72 years. Results: All suffered an infarction or hemorrhage in the territory of the middle cerebral artery of the non-dominant hemisphere and developed a bilateral palpebral ptosis. The recovery started after the fourth day. At the tenth day, eye opening was effortless and did not require frontal help, despite the persistence of hemiplegia. Conclusions: Cerebral Ptosis is a mimetic dysfunction of a specific non-injured area of the cerebral cortex, originated from a nearby parenchymal damage such as the middle cerebral artery of the same hemisphere. Cerebral Ptosis expresses the inhibition of the voluntary eyelid elevation center, of prefrontal location in the non-dominant hemisphere.
