Investigating the effect of signal strength on mean retinal nerve fibre layer

The aim of this study was to determine the effect of signal strength on mean retinal nerve fibre layer (RNFL) using spectralis optical coherence tomography (S-OCT). Thirty normal subjects were imaged with S-OCT using variably dense Bangerter foils to alter...

Clinical outcomes of a supplementary sulcus IOL

In this retrospective study, the authors examined 31 eyes of 20 patients who had received a supplementary trifocal sulcus IOL in addition to a ‘bag-in-the-lens’ IOL. Implantation of a ‘bag-in-the-lens’ IOL requires the creation of anterior and posterior capsulotomies, followed...

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,...

Using graphical illustration to predict giant cell arteritis

A nomogram is a chart or graph of scaled variables that facilitates the approximate computation of a mathematical function via intersecting lines. The objective of this study was to illustrate the use of a nomogram for the prediction of giant...

Employers asked to get in touch with ABDO College to support launch of new apprenticeship programme for dispensing opticians

ABDO College is calling on employers with experience of offering apprenticeships to get in touch. We aim to launch our apprenticeship programme for dispensing opticians in September 2024, subject to General Optical Council (GOC) approval.

Grading of ocular inflammation in uveitis: an overview

Anterior uveitis is the commonest form of uveitis, which can lead to severe morbidity if not treated appropriately [1]. Data from general ophthalmology practices suggest around 90% of uveitis encountered by comprehensive ophthalmologists is anterior uveitis [2]. Intermediate (vitreous), posterior...

Long-term outcome of ALPI for plateau iris syndrome

The purpose of this study was to evaluate the long-term outcomes of plateau iris syndrome (PIS) patients treated with argon laser peripheral iridoplasty (ALPI) following YAG laser peripheral iridotomy (LPI). Typical ALPI settings were a spot size of 200 to...

From trainee to teacher: Top tips for teaching fellow applications

Getting into ophthalmology training has become increasingly competitive in recent years. In 2025, the competition ratio rose to over 21:1, compared to 3:1 in 2019 [1,2]. Similar trends are seen across other specialties, with over 30,000 doctors applying for just...

Prediction errors of formulas in optical biometers

This study was conducted retrospectively in a private practice setting. Nine formulas were compared for prediction error (postoperative spherical equivalent (SE) minus, predicted SE calculated by each formula), using two optical biometers (Lenstar – optical low coherence reflectometry (OLCR) and...

Understanding optical lab processes at 100% Optical

Boosting understanding amongst the entire practice team about what happens in the optical lens manufacturing process was a keynote lecture which drew a packed audience to the OSA stand at 100% Optical.

Two cases of acute syphilitic posterior placoid chorioretinitis

Syphilis has re-emerged as a significant public health concern, with the World Health Organization (WHO) estimating that 8 million adults aged 15–49 acquired syphilis in 2022. Untreated syphilis can have severe consequences, including cardiovascular, neurological and ocular complications. Ocular manifestations...

Pegcetacoplan: A breakthrough treatment for dry age-related macular degeneration?

Age-related macular degeneration (AMD) is a degenerative condition affecting the macula, the part of the retina responsible for central vision. It is characterised by the presence of drusen and retinal pigment epithelium (RPE) abnormalities in the absence of other macular...
