Part 3: The Arclight Project: Implementation workshops

In this three-part series (Click here for Part 1 and Part 2) Andrew Blaikie and his team explore the role and application of the Arclight Device in Imaging of the Eye. The Arclight Project aims to support and enhance the...

Cataract surgery in uveitis patients

Cataract formation is a common complication of uveitis, causing up to 40% of vision loss in these patients. Cataract results from inflammation +/- corticosteroid therapy and is usually posterior subcapsular, but a small proportion have a rapid increase in nuclear...

Evaluation of keratometry with a novel colour LED corneal topographer

The Cassini topographer (i-Optics), which analyses corneal shape based on the reconstruction of specular reflections on 679 coloured LEDs, generates keratometry and is the new machine being compared in this study with other keratometry devices. The prospective comparative study included...

Relationship between nocturnal intraocular pressure elevation and diurnal intraocular pressure level in NTG patients

This group studies Korean normo-tension glaucoma (NTG) patients over a 24-hour period to assess if there was a relationship between nocturnal intraocular pressure (IOP) and diurnal IOP. They have previously suggested differences in diurnal IOP may have varying mechanisms of...

IOL power calculation formulas for myopic eyes undergoing cataract surgery after excimer laser

The authors set out to compare the accuracy of four no-history formulas: Barrett True-K, Haigis-L, Shammas-PL, and Triple-S to calculate the intraocular lens (IOL) power in eyes with previous myopic photorefractive keratectomy or laser in situ keratomileusis, according to their...

Feasibility and acceptability of virtual reality visual field testing compared to standard perimetry

The authors present a prospective pilot study which aimed to assess the feasibility and performance of the vivid vision perimeter (VVP). The VVP is a piece of software which can be used with off-the-shelf virtual reality (VR) headsets. Recruitment took...

ChatGPT cannot pass FRCOphth examinations: implications for ophthalmology and large language model artificial intelligence

Large language models are generating a lot of hype for artificial intelligence, but can they assist patients and practitioners in ophthalmology? Introduction Deep learning (DL) has emerged in ophthalmology as an exciting form of artificial intelligence (AI) most commonly applied...

Childhood glaucoma

When a child is given a diagnosis of glaucoma, the impact upon that child and their family is enormous; equivalent to the diagnosis of a cancer [14]. This previously published article (2019) outlines the knowledge, techniques and approaches that offer...

Pentacam vs. IOL Master keratometry measurement in IOL power calculations

The IOL Master measures only the anterior corneal curvature and estimates the total corneal power by assuming a fixed relationship between the anterior and posterior corneal surface. The Pentacam measures both the anterior and posterior corneal surface and therefore calculates...

What to expect when meeting a statistician

There are a growing number of statisticians working closely with ophthalmologists. They have different training but they are driven by the same goal: to perform high quality evidence based clinical research [1,2]. In a perfect world we would simply conduct...

Life’s rich tapestry

Have you ever watched someone cross-stitch, or do needle-point? I recently had the joy of observing my teenage daughter create such an artwork. She separated all the threads into the various colours, and then started to follow the instructions carefully....

The College of Optometrists and The Royal College of Ophthalmologists launch new joint vision for delivering eye care services across the UK

The College of Optometrists and The Royal College of Ophthalmologists (RCOphth) continue to review the ongoing impact of the pandemic on eye services across primary and secondary care.
