Corneal hysteresis: An emerging biomarker in the management of glaucoma

Corneal hysteresis (CH) is gaining recognition as a valuable parameter in the management of glaucoma. Corneal hysteresis is defined as the difference between the inward and outward pressure responses of the cornea during deformation. This measurement reflects the viscoelastic properties...

Randomisation, confounding & observational methods in ophthalmic epidemiology

Randomisation and confounding Understanding the relationship between an exposure and an outcome of interest is the central challenge in ophthalmic epidemiology. The exposure may be aetiological, taking the form of a putative risk biological factor, or therapeutic, in the form...

How do you solve the problem of trachoma in Ethiopia?

Background Trachoma is one of the oldest diseases known to humankind and the leading infectious cause of blindness worldwide. Spread by the bacterium chlamydia trachomatis, it is transmitted through contact with the eyes, eyelids and nose of those infected. The...

Best way to detect glaucoma progression: by reflecting on the past 25 years

Glaucoma – a condition of optic neuropathy leading to progressive visual field loss often associated with raised intraocular pressure. It is fair to say that our definition for this condition has remained unchanged over the last 25 years and the...

2018 update on intravitreal injections

In this review article the authors have highlighted the standardised and structured approach to intravitreal injections (IVI) by examining the recent evidence-based literature. IVI is the most commonly performed procedure worldwide with low potential risk of endophthalmitis. IOP spikes are...

Retinal vascular occlusion from gentamicin injection post-vitrectomy

The authors present two case reports for the rare, but serious, complication of retinal vascular occlusion as a presumed result of subconjunctival injection following 25-gauge vitrectomy. Risk factors for the complication include: cardiovascular disease, retrobulbar anaesthesia, high intraocular pressure (IOP)...

‘Phaco-plus’ procedures at forefront of modern glaucoma management

Glaucoma and cataract increasingly present as a ‘two-in-one’ surgical opportunity. In the UK, new modelling suggests ~1 million adults aged ≥40 may currently have glaucoma, with a projected rise to ~1.6 million by 2060 as the population ages and demographics...

Learnings and trends in the management of open-angle and angle-closure glaucoma

To be truly disruptive, newer technologies need to offer a quality of life benefit over medication to a broad population of glaucoma sufferers. Evidence and converging trends in medical and surgical management of glaucoma were explored in counterpoint discussions and...

Contemporary glaucoma therapy: spoilt for choice

The goal of glaucoma management is to prevent visual loss and disease progression in the patient’s lifetime through effective lowering of intraocular pressure (IOP), the primary modifiable risk factor in glaucoma. Sustained and consistent IOP reduction is key to halting...

More sensitive visual acuity test for age-related macular degeneration

Age-related macular degeneration (AMD) is the leading cause of blindness in the developed world. Primarily associated with ageing, genetic factors and lifestyle choices such as smoking also play a contributory role. Patients with early AMD, characterised by the development of...

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...

Glaucoma management after congenital cataract

The purpose of this study was to retrospectively explore the results of surgical intervention for glaucoma after congenital cataract surgery in Egypt. The study included 41 eyes of 32 children with glaucoma after cataract surgery – 57 procedures; 90% having...
