Eyelid Dysfunction in Neurodegenerative, Neurogenetic, and Neurometabolic Disease
Eye movement abnormalities are among the earliest clinical manifestations of inherited and acquired neurodegenerative diseases and play an integral role in their diagnosis. Eyelid movement is neuroanatomically linked to eye movement, and thus eyelid dysfunction can also be a distinguishing feature of neurodegenerative disease and complements eye movement abnormalities in helping us to understan...
متن کاملBlinking and eyelid myoclonia: Characteristics and correlations of eyelid movements
PURPOSE Eyelid myoclonia (EM) is considered a seizure type and has been described in several epileptic conditions. Previous studies reported that EM are precipitated only by slow eye closure, but little is known about the characteristics of blinking in patients with EM seizures and differences in precipitation of EM by different kinds of eye closure. We analyzed by video-EEG the characteristics...
متن کاملAsymmetry of blinking.
PURPOSE Too investigate asymmetry in eyelid movements with blinking, the stability of the asymmetry, and its modifiability in normal humans. METHODS Differences in the start time and amplitude between the two eyelids were assessed for voluntary blinks and reflex blinks evoked by supraorbital trigeminal nerve stimulation. These variables were also measured before and up to 18 months after 2 ho...
متن کاملHaemangiosarcoma of the Eyelid in a Four-Year Old Balami Ram
Case Description-A four-year old Balami ram weighing 120kg was presented to the University of Maiduguri Veterinary Teaching Hospital (UMVTH) with extensive swelling and ulceration of the nictating membrane of the left eye. Clinical Findings-A dark red hard mass on the third eyelid was covering the entire eyeball. The visible mass measured 5cm vertically and 7cm horizontally. Pus exudate was exp...
متن کاملNeurophysiological aspects of eye and eyelid movements during blinking in humans.
The neural relationships between eyelid movements and eye movements during spontaneous, voluntary, and reflex blinking in a group of healthy subjects were examined. Electromyographic (EMG) recording of the orbicularis oculi (OO) muscles was performed using surface electrodes. Concurrently, horizontal and vertical eye positions were recorded by means of the double magnetic induction (DMI) ring m...
