The Royal College of Ophthalmologists has issued advice and guidance for ophthalmologists regarding COVID-19.

Cementing a VISION 2020 LINK partnership between Blantyre and Liverpool – building capacity for DR services alongside research

Malawi is a small land-locked country in eastern Africa with a growing population of over 17 million people. About 45% of the population is aged 14 or under; only 5% are aged 60 or over. The gross national income per...

Ripasudil after Descemet stripping in Fuch’s endothelial dystrophy

This study prospectively evaluated the use of ripasudil, a rho kinase inhibitor, in patients undergoing Descemet’s stripping only (DSO) without an endothelial graft for Fuch’s endothelial dystrophy (FED). Patients with dense central guttae limited to the central 5mm of the...

How to diagnose and treat Acanthamoeba keratitis

Corneal ulceration caused by Acanthamoeba is on the rise, and recent publications indicate an outbreak in the UK over the last few years [1]. Since Acanthamoeba keratitis often presents with atypical features, diagnosis from slit-lamp examination alone can often be...

Novel retinal pigment metric tackles bias in AI models

Researchers have developed an innovative metric for objectively classifying pigmentation in a retinal image, rather than using subjective social constructs like ethnicity or other demographic variables, as is currently the case when building health datasets. Called the Retinal Pigment Score...

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.

The paediatric cataract: an overview of the embryology and pathophysiology

Comparison of SS-OCT and SD-OCT in polypoidal choroidal vasculopathy

Swept source OCT (SS-OCT) is known to have a longer wavelength than spectral domain OCT (SD-OCT), allowing deeper penetration into retinal and choroidal layers. The aim of this study was to investigate whether SS-OCT is superior to SD-OCT in imaging...

Progression of macular atrophy on long-term anti-VEGF therapy for AMD

This retrospective study evaluated the progression of macular atrophy in 53 eyes of 53 patients receiving AntiVEGF Therapy for age-related macular degeneration (nAMD), for at least six years. None of the patients had any macular atrophy (MA) at presentation. MA...

OCT prognostic factors in AMD patients with peripapillary choroidal neovascularisation

In this retrospective study the authors aimed to investigate the correlation between optical coherence tomography (OCT) findings and visual acuity outcomes after treatment with intravitreal bevacizumab (IVB) injections for age-related macular degeneration (AMD) patients with peripapillary choroidal neovascularisation (PPCNV). Data...

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...
