Blinking Parameters Do Not Normalize After Botulinum Toxin Therapy in Blepharospasm and Hemifacial Spasm Patients.
[BACKGROUND] Little is known regarding changes induced by botulinum toxin injections on blinking parameters in blepharospasm (BSP) and hemifacial spasm (HFS) patients. The purpose of this study was to investigate objective changes induced b…

Effect of chronic cocaine use on fine motor coordination tested during ophthalmic vitreoretinal simulated performance.
We conducted a case-control study using the Eyesi simulator to assess the surgical performance of 24 chronic cocaine users (CCUs) and 24 sex-/age-matched controls to numerically quantify ophthalmic microsurgical simulator performance and fi…

Association of Weight-Adjusted Caffeine and β-Blocker Use With Ophthalmology Fellow Performance During Simulated Vitreoretinal Microsurgery.
[IMPORTANCE] Vitreoretinal surgery can be technically challenging and is limited by physiologic characteristics of the surgeon. Factors that improve accuracy and precision of the vitreoretinal surgeon are invaluable to surgical performance.…

Analysis of blink activity and anomalous eyelid movements in patients with hemifacial spasm.
To assess spontaneous blinking and anomalous eyelid movements in patients with hemifacial spasm with an emphasis on interocular differences. Spontaneous eyelid movements were registered bilaterally for 3 min using a high-speed video camera …

Evaluation of botulinum toxin effects in hemifacial spasm patients: correlation between clinical rating scales and high-speed video system measurements.
The purpose of this study was to compare the scores of two clinical rating scales and high-speed video system measurements obtained during spontaneous eyelid movements in hemifacial spasm (HFS) patients before and after treatment. Patients …

An objective tool to measure the effect of botulinum toxin in blepharospasm and hemifacial spasm.
[BACKGROUND AND PURPOSE] It is challenging to assess patients with blepharospasm (BSP) and hemifacial spasm (HFS) as these patients exhibit a wide range of amplitudes of eyelid movements. In order to quantify these movements, a mathematical…

Orbicularis Oculi Morphological Alterations in Affected and Nonaffected Sides in Hemifacial Spasm.
[BACKGROUND] Although the nonaffected side appears to be clinically normal in hemifacial spasm (HFS), it is not known whether this side can be considered normal regarding histopathological findings. The purpose of this study was to objectiv…
