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...

Ciliary body granuloma masquerading as a melanoma

Introduction Sarcoidosis is a multisystem granulomatous inflammatory condition which predominantly affects the pulmonary system and intrathoracic lymph nodes, followed by ocular involvement [1]. We present an interesting patient who developed acute anterior uveitis and subsequent ciliary body granuloma clinically mimicking...

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...

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...

The management of watery eye in an infant with facial dysmorphism

A six-month-old child with facial dysmorphism is brought to the eye clinic with history of watery right eye since birth. How will you manage this child? Causes for watery eye in an infant 1. Overproduction of tears a. Infections b....

Adaptive optics imaging: resolving single cells in the living eye

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

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

Evolving towards an interventional glaucoma mindset

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?

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...

The Global Vision Database

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)

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...
