Emerging developments in dry eye

An estimated 344 million people worldwide suffer from dry eye [1]. This chronic syndrome is characterised by a vicious cycle of tear film hyperosmolarity, tear instability and corneal stress, leading to increased friction, inflammation, ocular surface damage and decreased visual...

An update on idiopathic intracranial hypertension

The incidence of Idiopathic intracranial hypertension (IIH) is increasing, likely in line with the worldwide epidemic of obesity. To date, there have been revisions in the terminology used and diagnostic criteria for IIH; these recognise the need to exclude secondary...

Intraocular lens technology to deliver enhanced optical performance after cataract refractive surgery

Modern cataract surgery aims to provide patients with the best possible visual outcome with the least dependence on spectacles and minimal or no complications and to treat both cataract and refractive errors with a single procedure. Phacoemulsification is the standard...

A closer look at the new wave of glaucoma surgery – radical or old school?

Glaucoma is a challenging condition to treat because the exact pathophysiology remains unclear and the only readily modifiable factor is the intraocular pressure (IOP). Additionally, most glaucoma patients are completely asymptomatic, yet are often subjected to lifelong medical therapy. The...

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...

A paradigm shift in the way we approach cataract surgery

Cataract surgery is the most common elective surgical procedure in the UK [1], with in the region of 350,000 cases being conducted each year. With an ageing population, this figure will only continue to rise over time. Cataract surgery is...

Retinopathy of prematurity treatment in the South West of England: long-term outcomes 1997-2008

Retinopathy of prematurity (ROP) is a condition that affects the developing retinal vascular system of pre-term babies. If left untreated, ROP can lead to severe visual impairment. The severe visual impairment caused by untreated ROP can be prevented by screening...

An introduction to research governance

Research is the process of acquiring new generalisable knowledge and should be fully integrated into health care work. There is a growing drive to encourage and further develop evidence-based practice in ophthalmology so that staff and patients benefit from improved...

“Steel True, Blade Straight”

Steven Kerr of the Royal College of Surgeons of Edinburgh explores the medical career of Arthur Conan Doyle, his relationship with his mentor Joseph Bell and his fascination with ophthalmology. Arthur Ignatius Conan Doyle was born in Edinburgh on the...

IN FOCUS - VISION 2020 LINKS Programme: the contribution of health partnerships to reduction in blindness worldwide

As other articles in this series (IN FOCUS Apr 2020) demonstrate, the year 2020 is highly significant in the eye care field. Naming a global initiative ‘VISION 2020: The Right to Sight’ in 1999 was a daring way to focus...

The management of retinal vein occlusions: a summary

Retinal vein occlusions (RVO) are the most common cause of visual loss from retinal vascular disease second to diabetic retinopathy. Vision is lost due to ischaemia, macular oedema and / or haemorrhage which ultimately effects a patient’s quality of life...

Designing ophthalmology services - Part 1: How do we address the queues in a clinic?

This first of a three-part series shows how systems engineering can be used to correctly diagnose and address the causes of delays in a clinic. The second article, which will be featured in the April/May 2020 issue, describes how to...
