Optical coherence tomography – reinventing the eye examination

It has been 25 years since Huang et al. presented the first optical coherence tomography (OCT) images in Science [1]. With vast improvements in OCT technology over the years, it is now possible to acquire high-resolution cross-sectional images of the...

OCTA in angioid streaks

This paper reports on the optical coherence tomography angiography (OCTA) features of choroidal neovascularisation (CNV) secondary to angioid streaks and the ability to predict CNV activity. A total of 38 eyes of 19 patients were included in the study. Thirty...

TowardPi Brings Next-Generation OCT/A to the UK

TowardPi, a fast-growing leader in ophthalmic imaging, has entered the UK market with its advanced swept-source OCT (SS-OCT) and OCT angiography (OCTA) systems. Distributed exclusively by Mainline Instruments, TowardPi is already well-established in Asia and is recognised for pioneering the...

Positive diagnosis of acute posterior ischaemic optic nerve neuropathy

Posterior ischaemic optic neuropathy is a rare cause of visual loss believed to be due to infarction in the territory of the pial branches of the ophthalmic artery. There is an absence of clinical signs which means the diagnosis is...

Diagnosis and management of orbital vascular malformations

This is an authoritative review of a controversial and difficult clinical area. The authors have experience of over 350 cases and provide a well-structured review of the classification and management of orbital vascular malformations. They emphasise the need to understand...

Spectral domain OCT vs. confocal scanning laser ophthalmoscope in measuring RNFL thickness

The aim of this prospective study was to compare the retinal nerve fibre layer thickness (RNFL) measurements obtained from the Cirrus optical coherence tomography (spectral domain OCT) with the Heidelberg Retinal Tomograph 3 (HRT3, confocal scanning laser ophthalmoscope). Eighty-eight normal...

Scheimpflug vs. OCT in measuring corneal thickness

The authors report on the reproducibility and repeatability of corneal thickness measurements using three different Scheimpflug imaging cameras (Pentacam, Sirius and Galilei) and one Fourier-domain optical coherence tomography (OCT) system (RTvue-100). The rationale for this study is that corneal thickness...

Swept source anterior segment OCT

The authors describe a study using the Casia OCT which is a swept source OCT to determine the visibility of the angle structures using two imaging protocols; high density and low density. They randomly selected one eye from 30 normal...

Things I’d tell my medical school self, had I known my first year on the job would be during a global pandemic

In a conversation with his younger self, a foundation doctor reflects on the contrast between his expectations of medicine at university and the reality of working during the coronavirus pandemic. Every doctor arrives at medical school with nervous anticipation, yet...

Handbook of Retinal OCT (Second Edition)

Duker et al. present the second edition of their Handbook of Retinal OCT. It’s an upgrade from their last edition in many respects – there’s an enhanced digital version, the pages have a nice glossy sheen which makes it feel...
