“…Deficient inhibition would result in lid retraction on gaze straight ahead or lid lag with downgaze [147]. A clinicopathological retrospective correlation study based on animal [18,148] and human [149] case studies delineated the nPC as the most likely lesion site for lid retraction [19]. This is consistent with very few eyelidand vertical saccade-related burst neurons that have been recorded in nPC [150].…”

Lid and electromyographic recordings have contributed significantly to our understanding of clinical lid disorders. Tonic lid disorders (e.g. ptosis, blepharospasm, lid retraction, blepharocolysis) can be distinguished from dynamic lid disorders (lid lag) and from specific deficits of eye-lid coordination (e.g. lid nystagmus). Electromyographic recordings allow the identification of specific lid disorders that benefit from effective therapeutic interventions, e.g., botulinum toxin injections. Rapid lid closure (blink), which exerts substantial neural influence on oculomotor systems without obscuring vision, can be used for the diagnosis of brainstem disease.

“…Impairment of some pons and rostral midbrain area lesions is thought to be relevant to the BCO-BSP disorder. Furthermore, bilateral subthalamotomy reportedly provokes involuntary eyelid movement [ 7 ]. Hyperinhibition of LPS activation is associated with the complete loss of ongoing OrbOcu contraction in these BSP-BCO disorders [ 3 ].…”

Simultaneous Loss of Bilateral Voluntary Eyelid Opening and Sustained Winking Response Following Bilateral Posterior Cerebral Artery Infarction

Spontaneous opening and closing of both eyes usually occurs in the normal awake state, unless a deliberate and voluntary attempt is made to open only one eye. We present a rare case of a male patient who was unable to open both eyes simultaneously after bilateral posterior cerebral artery infarction. He was able to close both eyes voluntarily. However, he was unable to keep both eyes open simultaneously and either the right or left eye remained closed. Upon a verbal command to open both eyes, the opened eye closed and the contralateral eye opened. When the closed eye was forced open, the opened eye closed. We thus presented a case of right-left dissociation of voluntary eyelid opening following bilateral posterior cerebral artery infarction, which was treated with botulinum toxin type A injection. Differential diagnosis to other movement disorders of the eyelids was discussed.

“…Sabe-se que estruturas corticais, como o córtex visual e o giro frontal medial, têm correspondência também com o piscar espontâneo (Yoon et al, 2005). Áreas prémotoras relacionadas ao fechamento palpebral situam-se próximas ao colículo superior, substância cinzenta periaquedutal e comissura posterior, já as áreas relacionadas à abertura ocular estão abaixo do colículo superior, próximas ao núcleo caudado e tegumento dorsolateral do cérebro médio (Nashold;Gills;Wilson, 1967).…”
