Microcatheter in the vertebral artery as a cause of branched retinal artery occlusion?

A 19-year-old male presented to eye casualty with a seven-day history of a ‘blurred patch’ in the left eye. The patient denied any other visual symptoms including flashes or floaters and there had been no change in visual symptoms in...

Restoration of colour perception in patients with retinitis pigmentosa

This is a case series testing the feasibility of using bioelectronic retinal prostheses to partially restore colour perception in seven patients with advanced retinitis pigmentosa. Bioelectronic retinal prostheses are able to bypass degenerated photoreceptors to directly stimulate the inner retinal...

Atlas of Wide-Field Retinal Angiography and Imaging

Through extensive illustrations, this book, comprehensively yet concisely, covers the diagnostic speciality of wide-field retinal angiography and imaging. There are 15 chapters with contributions from 29 leading experts in this particular field who are mainly based in the USA, but...

Nicotine accelerates diabetes induced retinal changes

This study investigated the influence of nicotine in an experimentally induced diabetic rat model. They used non-invasive high-resolution spectral domain optical coherence tomography (SD-OCT) imaging to provide quantitative information on the temporal alterations of retinal structures at the micrometer resolution...

OCT Angiography in Retinal and Macular Diseases

OCT angiography (OCT-A) is based on the concept that in a static eye, the only moving structure in the fundus of the eye is blood flowing through the vessels. This book explains how the technique allows a depth-resolved analysis and...

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...

Normal reference values for the RETeval device

The purpose of this study was to provide normative data of full-field electroretinography (ERG) responses in the paediatric population using the RETeval device in healthy children with normal retinas. This was a prospective study of 38 eyes of 20 patients...

Retinal morphology after PASCAL PRP treatment

The authors of this prospective cohort study set out to report the changes on Spectral Domain-OCT of PASCAL panretinal laser photocoagulation (PRP) treatment for proliferative diabetic retinopathy (PDR) or severe nonproliferative DR (NPDR) and the retinal morphology, from one hour...

OCTA in geographic atrophy

In this article the authors aim to give an overview of the current literature concerning the application of OCT-A in geographic atrophy (GA). GA is a disease characterised by loss of outer retinal layers including photoreceptors, degeneration of the retinal...

OCT angiography sign after whiplash

Berlin’s oedema is a rare condition following blunt ocular injury and a rare finding after whiplash injury. This case describes a 48-year-old male who suffered a seventh vertebrae fracture from a traffic accident. Two days later, decreased left eye visual...

ROP anti-VEGF treatment review

The purpose of this review was to consider data relating to risks and benefits of the use of anti-VEGF treatment for retinopathy of prematurity (ROP) over the past five years of 2015-2020. Ocular benefits include treatment of aggressive posterior ROP,...

Ocular bubbly: a vitreoretinal update on the art of gases

The authors remind us of the revolutionary impact gases have had on retinal surgery. In 1938, Rosengren attempted to improve his retina repair surgical outcomes [1]. He discovered that suturing the retina or pressing externally on the sclera were not...
