Abstract

CARTIER R., Luis; PARRA, Jorge  and  CONTRERAS S., Juan P.. Cerebral ptosis. Analysis of six cases. Rev. méd. Chile [online]. 2018, vol.146, n.8, pp.857-863. ISSN 0034-9887.  http://dx.doi.org/10.4067/s0034-98872018000800857.

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.
