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...

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.

Eye scans detect signs of Parkinson’s disease up to seven years before diagnosis

A team led by Siegfried Wagner and Pearse Keane of Moorfields Eye Hospital and UCL Institute of Ophthalmology (and spanning UCL institutions) has identified markers that indicate the presence of Parkinson’s disease in patients on average seven years before clinical presentation.

GREG: Optical Coherence Tomography (OCT) Qualifications – March 2025 cohort application deadline

Gloucestershire Research & Education Group in Partnership with the University of Gloucestershire are pleased to provide both the Cert HE in OCT Capture and the Uni Dip in OCT Interpretation.

These qualifications have been designed to meet the needs of routine operators of OCT equipment and interpreters of OCT scans. For further information visit www.gregcourses.com

A new observation point: updating the nomenclature and classification with OCT

The evolution of ophthalmic imaging technologies has been particularly rapid over the last few years. The author provides an update of the current terms for common signs and pathologies observed using optical coherence tomography. My experience as an ophthalmic technician,...

DRIL after macular oedema treatment in BRVO

The authors report the analysis of a single-site, retrospective, cross-sectional study to evaluate the association between disorganisation of the retinal inner layers (DRIL) and visual acuity (VA) after anti-VEGF treatment for macular oedema (MO) due to branch retinal vein occlusion...
