Retracción palpebral de causa neurológica: Presentación de tres pacientes, interpretación patogénica

Eyelid retraction, has received limited attention and it has passively been interpreted as the result of an overactive levator palpebrae superioris muscle secondary to midbrain injury. However, eyelid retractions can occur in other neurological diseases, not directly related with the midbrain. We re...

description	Eyelid retraction, has received limited attention and it has passively been interpreted as the result of an overactive levator palpebrae superioris muscle secondary to midbrain injury.
