Transsynaptic retrograde degeneration linked to homonymous visual field loss after stroke

centre, of individuals identified with homonymous visual field loss post ischaemic stroke. Exclusion criteria were bilateral ischaemia, anterior / pregeniculate visual pathway affected and other pathology with the potential to effect visual fields. The following were extracted from the medical...

College launches new assessor affixes to recognise expertise and commitment to optometric education

The College of Optometrists has launched a new suite of assessor affixes to recognise the expertise, commitment and professional judgement of College assessors and the vital role they play in developing the optometry workforce. Work-based assessment is central to optometric...

What’s next in retinal imaging? Faster, deeper and full-on

Fast-evolving technological leaps are opening the way toward clinically useful ocular coherence angiography, generating 3-dimensional microvasculature maps without intravenous dye injection, as well as whole-eye imaging, handheld patient-operated optical coherence tomography (OCT) devices and, for challenging vitreoretinal procedures, integrated intraoperative...

Exudative age-related macular degeneration

The authors looked at macular lesions in eyes with newly diagnosed exudative age-related macular degeneration. The eyes of 23 patients were included and tested for visual acuity, contrast sensitivity, microperimetry, optical coherence tomography (OCT) and fluorescein and indocyanine green angiography....

Density of cataract and its influence on retinal nerve fibre layer thickness

The aim of this study was to further define and model the influence of cataract on spectral domain optical coherence tomography (SDOCT) image quality and retinal nerve fibre layer (RNFL) thickness measurements. OCT quality is influenced by opacities in the...

Can OCT predict Alzheimer’s disease?

Simerdip Kaur takes a look at the latest ophthalmology-related news stories and asks which are based on facts and which are ‘fake news’. Headline: Can OCT predict Alzheimer’s disease? In 1986 Hinton et al. demonstrated evidence of optic nerve degeneration...

Coming to terms with AI

A machine might be called intelligent if its response to questions could convince a person that it was human, a test proposed by Alan Turing in 1950 [1]. The author considers potential applications of artificial intelligence (AI) using machine learning...

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...

Outcomes of treat & extend ranibizumab in diabetic macular oedema

This study retrospectively evaluated 118 eyes of 87 patients who received ranibizumab in a treat and extend regimen for diabetic macular oedema (DMO). Data were collected for patients under follow-up for 24 months. After 24 months, patients gained a mean...

Relating metamorphopsia severity and OCT findings in advanced epiretinal membranes

The authors present the findings of a retrospective study to correlate metamorphopsia and ectopic inner foveal layers (EIFL) or ‘central bouquet’ abnormality (CBA) in patients with advanced stages of epiretinal membrane (ERM) following the new OCT‐based grading scheme as described...

AI breakthrough brings geographic atrophy treatment a step closer

A team led by Dr Konstantinos Balaskas at Moorfields Eye Hospital Reading Centre has developed a fully automated, deep-learning model (algorithm) that can detect and quantify geographic atrophy using standard optical coherence tomography (OCT) scans.

ZEISS: Optimising Outcomes with OCT: From acquisition to advanced analysis. 2nd date

The course aims to equip participants with the foundational knowledge and practical skills needed to acquire and interpret Optical Coherence Tomography (OCT) images effectively and confidently. Content will be tailored to current and new users of OCT – but all...
