[BACKGROUND] Blepharoplasty rectifies functional and aesthetic problems of the periorbital area. [OBJECTIVE] This study tests the effectiveness of a combined procedure of blepharoplasty and fractional ablative CO resurfacing on a total of …

[PURPOSE] To objectively demonstrate eyelid spasms relief in hemifacial spasm (HFS) patients using a smartphone and a custom-made software. [METHODS] Nineteen patients with HFS had standardized videos recorded with a smartphone (iPhone 6S,…

[BACKGROUND AND PURPOSE] It is challenging to assess essential blepharospasm (EB) patients objectively because they exhibit chaotic patterns of abnormal eyelid movements. Previously employed objective approaches used systems with low levels…

[PURPOSE] The purpose of this study was to assess blepharospasm patients regarding the effect of botulinum toxin in ocular surface parameters. [METHODS] A prospective study was performed in blepharospasm patients treated with onabotulinumt…

[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…

[PURPOSE] Eyelid spasms might be associated with elevated intraocular pressure (IOP) in hemifacial spasm (HFS) patients. IOP assessment using a Goldmann applanation tonometer (GAT) is often compromised by eyelid spasms. This study aimed to …

Eyelid retraction related to thyroid eye disease (TED) is a challenging condition. It is one of the main clinical signs and a major diagnostic criterion in TED. This condition may threaten vision due to exposure keratopathy, in addition to …

[BACKGROUND] Periorbital fractional CO2 laser resurfacing has been employed for facial rejuvenation purposes. However, to the best of our knowledge, no study has objectively assessed periorbital neoformation and remodeling of local cutaneou…

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 …

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 …

[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…

[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…

[PURPOSE] There is anecdotal evidence that upper blepharoplasty might lead to raised intraocular pressure (IOP). If this association is confirmed, then patients with glaucoma and glaucoma suspects could be at risk if they underwent this pro…

[PURPOSE:] To evaluate whether reducing eyelid muscular force through the administration of botulinum toxin type A (BTX-A) to the orbicularis oculi muscles of patients with keratoconus affected corneal parameters indicative of disease progr…

[PURPOSE] In Asian patients, lateral hooding in the aging upper eyelid is prominent and frequently seen. Removal of the redundant skin of this region during classic blepharoplasty tends to produce a resultant prolonged scar. Furthermore, as…

[PURPOSE] To investigate possible temporary differences in corneal topographic parameters between affected and normal eyes in patients with hemifacial spasm (HFS) treated with botulinum toxin-A (BTX-A), over the course of 1 treatment cycle.…

[PURPOSE] To evaluate the effect of eyelid spasm treatment with botulinum toxin-A (BTX-A) on corneal curvature assessed with Scheimpflug (Pentacam) and Placido (Atlas) systems. [SETTING] Federal University of São Paulo, São Paulo, Brazil. …

[BACKGROUND/AIMS] In patients with hemifacial spasm (HFS), treatment relieves eyelid spasms on the affected side, thus changes in corneal topography and eyelid morphometry may be observed after treatment. We aimed to evaluate these paramete…
