Dr William Mackenzie: a founding figure of modern ophthalmology

The author looks at the career of William Mackenzie and the important role he played in establishing the status of ophthalmology as a recognised medical speciality. There are certain individuals who, blessed with ability and means, are destined to leave...

Tricks and tips for paediatric refraction

Refraction is an important part of the paediatric eye examination but can sometimes be challenging. If a child struggles to co-operate with the eye examination, how can one ensure that the best outcome is achieved? There are tips here which...

Surgical effect of limited membrane dissection

Strabismus surgery was performed with minimal dissection of Tenons sheath and minimal tissue manipulation compared to conventional methods for patients with pure horizontal strabismus – to evaluate the effect on surgical outcomes. The study included 54 patients; 52% female. Mean...

Quantum imaging research could improve retinal scans

New EU-funded feasibility project is testing a quantum approach that could reveal finer detail in the eye than ever before. A European research consortium is exploring a new quantum imaging technique that could one day help clinicians see the earliest...

Retrospective review of visual outcomes in Idiopathic intracranial hypertension (IIH)

Idiopathic intracranial hypertension (IIH) is a clinical syndrome characterised by headache and papilloedema that can lead to significant visual morbidity. IIH is diagnosed by the modified Dandy criteria, which include normal neuroimaging and cerebrospinal fluid (CSF) composition, high CSF opening...

Myopia rate of change from 5-20 years

Data was collected from the 2008-12 KNHANES survey and the study included 7695 of 9351 subjects with refractive data. The mean age was 11.8 years (5-20 range) with 48.2% female. Mean spherical equivalent was -1.82 ±2.23D. For five-year-olds, the mean...

The refractive index in the eye lens – implications for clinical practice and optical design

The eye may appear to be a comparatively simple organ and yet its optical system is complex and continues to be a source of investigation and research. The major optical elements are considered to be the cornea and the lens...

Use of a smartphone repair microscope for microsurgical suturing simulation

Suturing ocular tissues under microscopic guidance is a skill that has declined in frequency, with the majority of cataract operations being sutureless. With the recent COVID-19 outbreak, training opportunities in theatre have declined further, given elective surgery cancellations. Subsequently, trainees...

General purpose AI: Transitioning from high performance in highly curated settings to useful applications in ophthalmology

Artificial intelligence (AI) may be understood as the ability of machines to perform tasks which otherwise require human perception, reasoning, or learning. With the advent of deep learning, AI has achieved remarkable results across a wide range of medical tasks...

Germline mutation risk in solitary unilateral retinoblastoma

This study aimed to determine the true risk for germline mutation in a child presenting with solitary unilateral RB and whether this risk differs by age at presentation. This was a retrospective review of 482 cases from 1972-2020. Age groups...

Redeployment during the COVID-19 pandemic: personal accounts from four ophthalmology trainees

We once believed that the coronavirus would not penetrate the safe confines of the United Kingdom, like so many outbreaks before this. Once the news came that this pandemic descended into our hospitals, the anxieties about redeployment began. Many of...

The treachery of images – making sense of OCT imaging

In 1929 Belgian surrealist Rene Magritte produced his painting La Trahison des Images. It depicted an old fashioned pipe for smoking tobacco and underneath were the words “ceci n’est pas une pipe”, this is not a pipe. You may wonder...
