Adaptive optics imaging: resolving single cells in the living eye

1 June 2014 | | EYE - Cornea
The human retina is unique in the central nervous system (CNS) in that it can be directly visualised non-invasively. Technological advances of several imaging modalities, including optical coherence tomography (OCT), multichannel scanning laser ophthalmoscopy (SLO) and fundus photography, have afforded...

Twenty-five years in retina

1 February 2019 | | EYE - Vitreo-Retinal, EYE - General
In the next of our articles celebrating 25 years of Eye News, the authors look at how the retina specialty has changed over this time and ask what the future might hold. Retinal disease management has benefited from great advances...

A missed intraocular telescope – an opportunity to re-focus the evidence

4 February 2021 | | EYE - Cornea, EYE - Vitreo-Retinal, EYE - Imaging, EYE - General
Intraocular telescopes allow magnification of the image so that it would be projected into a larger area of the macula, this makes the central defect caused by dry age-related macular degeneration (AMD) smaller. The most common approach is a Galilean...

Evolving towards an interventional glaucoma mindset

2 February 2024 | | EYE - Glaucoma
Traditionally, a newly diagnosed glaucoma patient would be treated first with medical therapy. As the disease progressed or the initial intervention failed to adequately control intraocular pressure (IOP), clinicians would add more drops, selective laser trabeculoplasty (SLT), repeated SLT and...

Minimally Invasive Glaucoma Surgery: What options are there and when might they be considered?

25 March 2024 | | EYE - Glaucoma
In recent years there has been a rapid expansion in a group of operations termed ‘minimally invasive’ or ‘micro invasive’ glaucoma surgery (MIGS). These options generally offer less significant IOP reduction, but with a more favourable safety profile when compared...

Ultra-widefield imaging in glaucoma: Documenting hypotony-related choroidal effusions after microshunt surgery

3 April 2026 | | EYE - Glaucoma, EYE - Imaging
Ultra-widefield (UWF) imaging provides extended visualisation of the posterior segment beyond the traditional 30–50° field of view. It captures a broad view of the posterior pole and periphery in a single, quick, non-mydriatic acquisition. While its role in diabetic retinopathy...

The Global Vision Database

1 December 2015 | | EYE - General
The overall goal of the Global Vision Database (GVD) [1] is to develop and deploy new and improved evidence on the prevalence of blindness and vision impairment (VI) globally. It is a repository which allows us to assess the causes...

The interpretation and use of ultrasound biomicroscopy (part 1)

1 October 2016 | | EYE - Cornea, EYE - Imaging, EYE - Vitreo-Retinal
Ultrasound Biomicroscopy (UBM) has become increasingly important for the diagnosis of a variety of anterior segment pathologies. Most ophthalmologists are familiar with conventional B-scan ultrasonography techniques, which operate at lower sound frequencies (7.5 to 20MHz). UBM is an ultrasound technique...

Corneal hysteresis: An emerging biomarker in the management of glaucoma

2 October 2025 | | EYE - Cornea
Corneal hysteresis (CH) is gaining recognition as a valuable parameter in the management of glaucoma. Corneal hysteresis is defined as the difference between the inward and outward pressure responses of the cornea during deformation. This measurement reflects the viscoelastic properties...

Diabetic Retinopathy Network laser training programme

5 February 2020 | | EYE - Vitreo-Retinal, EYE - General
The VISION 2020 Diabetic Retinopathy Network (DR-NET) was established in 2014 to tackle the increasing burden of diabetes and diabetic retinopathy (DR) in developing countries [1]. By forming a network of long-term LINK capacity-building partnerships, learning and best practice can...

The treachery of images – making sense of OCT imaging

1 June 2016 | | EYE - Vitreo-Retinal, EYE - 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...

Troubleshooting in LASIK

1 April 2017 | | EYE - Cataract, EYE - Refractive
Contemporary laser in situ keratomileusis (LASIK) is safe and effective. It remains the dominant intervention in routine refractive surgery for a good reason: predictable results, rapid visual recovery, and relatively simple strategies for revision treatment. Over 95% of patients are...
