“Please phone Mr C Lyon ASAP on 0131 334 9171” This was a message from my secretary waiting for me on my computer one morning shortly after I was appointed a consultant. The name did not ring any bells but...

Optical coherence tomography – reinventing the eye examination

It has been 25 years since Huang et al. presented the first optical coherence tomography (OCT) images in Science [1]. With vast improvements in OCT technology over the years, it is now possible to acquire high-resolution cross-sectional images of the...

A missed opportunity

Back in 2000 Sir Liam Donaldson wrote a piece of work commissioned by the then Secretary of State for Health entitled “An Organisation with a Memory”. We are now 18 years on and still some of the recommendations from them...

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...

Assessing the effectiveness of undergraduate ophthalmic assessments in the UK: A literature review

During 2008–2009, 300,000 patients presented to hospital emergency departments in the UK with eye conditions. This rose by nearly 200,000 over the next decade. As the population ages, the prevalence of eye disease increases [1,2]. However, the stake ophthalmology holds...

Open-field autorefraction screening

This study aimed to determine the efficacy of the Shin-Nippon NVision-K5001 autorefractometer using the open-field refractometry principle in the elimination of accommodation in children. One hundred and fourteen patients aged three to six years were recruited. After excluding ocular pathology...

Improving vision screening access

The purpose of this study was to determine whether providing access to instrument-based screening equipment would increase the total number of high quality age-appropriate vision screenings provided to pre-school aged children. SPOT vision screening was placed in paediatric offices at...

A brief history of colour vision

Andrew Want takes a look at how colour vision has evolved in humans and animals and how it differs across species. Colour vision is something that we often take for granted, but it has become so intrinsic to the way...

Measuring cyclotorsion

The aim of this study was to investigate if different methods of measuring cyclotorsion (synoptophore, KM screen test and single Maddox rod test) produce the same results and if these values are repeatable in adult patients. For the synoptophore, the...

Screening accuracy

In this study the authors observed whether and how well orthoptic tests are performed by non-orthoptists in a screening setting. They assessed the quality of screening tests by semi-structured observations of youth health care (YHC) physicians who screened children aged...

Iranian values for childhood convergence

The authors aimed to determine near point of convergence (NPC) values in a population-based study in Iranian schoolchildren with a large sample size. They explored its relation to factors such as age, gender, refractive error and near point of accommodation....

Glaucoma screening in primary care and community settings

Glaucoma is one of the most common causes of irreversible blindness in the United States due to its insidious progression and diagnosis in late stages. The cost-effectiveness of screening for glaucoma has been debated, and screening of high-risk groups for...
