Long-term use of botulinum toxin for hemifacial spasm and blepharospasm

The authors conducted a retrospective review of clinical / procedure documentation for consecutive blepharospasm (BEB) and hemifacial spasm (HFS) patients undergoing treatment with onabotulinum toxin A (Botox) in one clinic setting over the past 20 years. They report on the...

Ocular motility disturbances after glaucoma drainage device

This is a cross-sectional study of children (<17-years-old) with a glaucoma drainage device (GDD) (Ahmed vs Baerveldt) implanted consecutively by a single surgeon from the Toronto group, between September 2006 and May 2018 and who had an ocular motility examination...

Trabeculectomy for normal tension glaucoma

This is a retrospective consecutive, non-comparative case series of 131 eyes of 98 patients undergoing trabeculectomy between 2007 and 2013 in a normal tension glaucoma (NTG) clinic. Assessment of the clinical outcomes include intraocular pressures (IOP) reduction, bleb formation, final...

Ozurdex wound leakage

This letter to the editor describes two cases of wound leakage after Ozurdex injection. The first case is a man who had four previous injections for an underlying diagnosis of chronic serpiginous choroiditis, who was also on a course of...

Effect of trabeculectomy on corneal endothelial cell loss

This is a prospective study of 117 eyes for two years after trabeculectomy, to investigate the corneal endothelial cell density (CECD) by specular microscopy prior to and after surgery on a six monthly basis. At six, 12, 18 and 24...

The lived experience of benign essential blepharospasm

Benign essential blepharospasm (BEB) is a rare neurological condition which causes involuntary sustained or intermittent muscular contraction of both eyelids and upper facial muscles which cause closure of eyelids, abnormal facial expressions and distress [1]. The term dystonia is an...

Could medical cannabis be used to successfully treat blepharospam?

This study observed the effect of medical cannabis in benign essential blepharospasm (BEB), in addition to standard botulinum toxin treatment. The study comprised of a retrospective chart review on eligible patients and included information on patient demographics, responses, cannabis history...

Improved efficacy expected with second-generation microinvasive glaucoma surgery (MIGS) devices

Microinvasive surgical approaches to primary open-angle glaucoma (POAG) offer minimally traumatic options for effective intraocular pressure (IOP) reduction in appropriately selected glaucoma patients. Increases in laser trabeculoplasty rates and wider adoption of glaucoma drainage device filtration procedures, together with the...

Severe conjunctival cicatrisation secondary to chronic glaucoma therapy

The timing of glaucoma filteration surgery during the course of chronic progressive glaucoma remains a contentious issue amongst glaucoma specialists. The vast majority support the use of maximal medical treatment initially to achieve the target pressure. Surgical procedures are only...

Clinical and management strategies in glaucoma practice: perspectives from international glaucoma specialists

Management options and outcomes in glaucoma practice were reviewed at the 7th Moorfields International Glaucoma Symposium, held in London on 24 January 2015. This article summarises perspectives from international glaucoma specialists on debated issues in topical therapy, glaucoma surgery, diagnostic...

Aqueous misdirection: a case series of unexpected surgical complications

Aqueous misdirection (AM), also known as malignant glaucoma, is a form of secondary glaucoma that typically presents with shallowing of the anterior chamber (AC), raised intraocular pressure (IOP), and reduced visual acuity (VA) in the presence of patent peripheral iridotomies...

Minimally Invasive Glaucoma Surgery: What options are there and when might they be considered?

In recent years there has been a rapid expansion in a group of operations termed ‘minimally invasive’ or ‘micro invasive’ glaucoma surgery (MIGS). These options generally offer less significant IOP reduction, but with a more favourable safety profile when compared...
