Curr Opin Ophthalmol 2018 Jun 18. Epub 2018 Jun 18.

Department of Ophthalmology, Cullen Eye Institute, Baylor College of Medicine, Houston, Texas, USA.

Purpose Of Review: To review new developments in the medical and surgical treatment options for benign essential blepharospasm (BEB).

Recent Findings: Botulinum toxin injections remain the mainstay treatment for BEB with several formulations currently commercially available. Reports in the medical literature support photochromatic modulation for the symptoms of photophobia, as well as oral medications and surgical myectomy for control of the motor signs of eyelid protractor spasm.

Increase lipid tear thickness after botulinum neurotoxin A injection in patients with blepharospasm and hemifacial spasm.

Sci Rep 2018 May 30;8(1):8367. Epub 2018 May 30.

Department of Ophthalmology, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University College of Medicine, Kaohsiung, Taiwan.

The aim of this study was to investigate changes in the tear film lipid layer thickness (LLT) and aqueous tear production after botulinum neurotoxin A (BoNT) injection in patients with benign essential blepharospasm (BEB) and hemifacial spasm (HFS). Eleven and six patients with BEB and HFS, respectively, who received BoNT injection were consecutively enrolled in this prospective study. The blepharospasm disability index (BSDI), blink pattern, dry eye symptoms, Schirmer test 1 findings, LLT, eyelid performance, and corneal integrity were evaluated before and after treatment.

Diagnosis of primary hemifacial spasm.

Neurochirurgie 2018 May 16;64(2):82-86. Epub 2018 Apr 16.

Service de neurochirurgie, fondation ophtalmologique Adolphe-de-Rothschild, 75019 Paris, France.

The diagnosis of primary hemifacial spasm (pHFS), due to a benign compression of the facial motor nerve by a vessel, within or close to its root exit zone, is often made with delay. Misdiagnosis includes psychogenic spasm, tics, facial myokymia or blepharospasm, but in fact post-facial palsy synkinesis (post-paralytic HFS) is the closest clinical condition, because it is limited to the territory of the facial nerve of a single hemiface. The differential diagnosis between these two entities, whose pathophysiological mechanisms are very different, can be made by electroneuromyographic (ENMG) examination. Read More

Surgical approach to limiting skin contracture following protractor myectomy for essential blepharospasm.

Digit J Ophthalmol 2017 5;23(4):8-12. Epub 2017 Nov 5.

Department of Ophthalmology and Visual Sciences, Kentucky Lions Eye Center, University of Louisville, Louisville, Kentucky.

Purpose: To report our experience with protractor myectomy in patients with benign essential blepharospasm who did not respond to serial botulinum toxin injection, and to describe intra- and postoperative techniques that limited skin contracture while also providing excellent functional and cosmetic results.

Methods: The medical records of patients with isolated, benign, essential blepharospasm who underwent protractor myectomy from 2005 to 2008 by a single surgeon were reviewed retrospectively. The technique entailed operating on a single eyelid during each procedure, using a complete en bloc resection of all orbicularis tissue, leaving all eyelid skin intact at the time of surgery, and placing the lid under stretch with Frost suture and applying a pressure dressing for 5-7 days.

Physiological effects of subthalamic nucleus deep brain stimulation surgery in cervical dystonia.

J Neurol Neurosurg Psychiatry 2018 Jan 11. Epub 2018 Jan 11.

Department of Neurology, University of Florida, Gainesville, Florida, USA.

Background: Subthalamic nucleus deep brain stimulation (STN DBS) surgery is clinically effective for treatment of cervical dystonia; however, the underlying physiology has not been examined. We used transcranial magnetic stimulation (TMS) to examine the effects of STN DBS on sensorimotor integration, sensorimotor plasticity and motor cortex excitability, which are identified as the key pathophysiological features underlying dystonia.

Methods: TMS paradigms of short latency afferent inhibition (SAI) and long latency afferent inhibition (LAI) were used to examine the sensorimotor integration. Read More

A comparative crossover study on the treatment of hemifacial spasm and blepharospasm: preseptal and pretarsal botulinum toxin injection techniques.

Neurol Sci 2017 Nov 7;38(11):2031-2036. Epub 2017 Sep 7.

Neurology Division, Department of Internal Medicine, Faculty of Medicine, Thammasat University, Pathumthani, Thailand.

Hemifacial spasm (HFS) and benign essential blepharospasm (BEB) are chronic and disabling abnormal craniofacial movements that produce involuntary eyelid twitching and closure. The efficacy and safety of botulinum toxin type A (BoNT-A) injections have been accepted and widely used for the treatment of HFS and BEB. However, different injection sites may influence the effectiveness, doses, and side effects. Read More

Computational Neurobiology Laboratory, Salk Institute for Biological StudiesSan Diego, CA, USA; Institute for Neural Computation, University of California, San DiegoSan Diego, CA, USA.

Blepharospasm (sometimes called "benign essential blepharospasm," BEB) is one of the most common focal dystonias. It involves involuntary eyelid spasms, eye closure, and increased blinking. Despite the success of botulinum toxin injections and, in some cases, pharmacologic or surgical interventions, BEB treatments are not completely efficacious and only symptomatic. Read More

Photophobia in primary headaches, in essential blepharospasm and in major depression.

Int J Neurosci 2017 Aug 13;127(8):673-679. Epub 2016 Sep 13.

a Department of Neurology, Eginition Hospital , University of Athens , Athens , Greece.

Objectives: Although photophobia is a well-known symptom in various disorders, it has rarely been studied explicitly and its definition in a clinical setting can be somewhat elusive. Here, we assessed photophobia with a common psychometric tool in different conditions, in which light intolerance is considered part of the syndrome.

Patients And Methods: A prospective study was undertaken in patients with migraine (MH), cluster headache (CH), tension-type headache (TH), essential blepharospasm (BS) and major depression (MD). Read More

Cognitive Flexibility in Primary Dystonia.

J Int Neuropsychol Soc 2016 07;22(6):662-70

Department of Neurology,Hannover Medical School,Hannover,Germany.

Objectives Although primary dystonia is typically characterized as a movement disorder, it is also associated with cognitive alterations in the domain of executive functioning which may arise from changes in cortico-basal ganglia circuits. Specifically, in comparison to healthy controls, patients with dystonia show deficits in neuropsychological tests of cognitive flexibility. However, it is unclear whether cognitive inflexibility is caused by the pathomechanisms underlying primary dystonia or by confounding factors such as depression or symptom-related distraction.

State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou 510060, China.

The aim of this study was to evaluate the efficacy of two botulinum toxin A (BoNT-A) injection patterns with or without the medial lower eyelid (MLE) in treating benign essential blepharospasm (BEB) and influencing lacrimal drainage. Two different injection patterns of BoNT-A were randomly applied to 98 eyes of 49 BEB patients: MLE Group received a full injection pattern of 5 sites and non-MLE Group received a MLE waived injection pattern of 4 sites. Tear breakup time (BUT), Schirmer I test, lagophthalmos height, and lower lid tear meniscus height (TMH) were measured and Jankovic Rating Scale (JRS) was surveyed before injection and at 1 week, 1 month, and 3 months after injection.

J Cosmet Laser Ther 2014 Oct 2;16(5):258-62. Epub 2014 Sep 2.

University of California Irvine, Dept. of Dermatology , Englewood, CO , USA.

Introduction: A recent paper in the Journal of Drugs in Dermatology by Koshy and colleagues (2012, 11( 4 ):507-512) report on "Effect of Dietary Zinc and Phytase Supplementation on Botulinum Toxin Treatments" and conclude by claiming the discovery of "a potentially meaningful role for zinc and/or phytase supplementation in increasing the degree and duration of botulinum toxin effect in the treatment of cosmetic facial rhytids, benign essential blepharospasm, and hemifacial spasm". The purpose of this paper is to examine these published claims for possible methodological and design errors and potential sources of bias.

Methods: The authors evaluated the published results in comparison to the published literature on zinc deficiency, the role of phytase, prior reports of an effect of zinc on activity of botulinum toxin, issues of study design and execution and if the reported results of the study supported the study's conclusions.
