A brief history of colour vision

Andrew Want takes a look at how colour vision has evolved in humans and animals and how it differs across species. Colour vision is something that we often take for granted, but it has become so intrinsic to the way...

Across the globe and into the world of international eye grading

Decades have passed and the influence of analysing fundus images by grading consultants and retinal image specialists has grown worldwide. Their job is to specialise in assessing hundreds of diagnosed eye disease disorders and to read thousands of eye images,...

Like a moth to AC flare: CMV-associated hypertensive anterior uveitis

Hypertensive anterior uveitis can present a diagnostic challenge to clinicians working in emergency eye departments. While prompt initial control of intraocular pressure (IOP) and inflammation is essential, elucidating the underlying aetiology is critical for long-term visual outcomes. When there is...

Anterior segment OCT imaging in cases of episcleritis and scleritis

The purpose of this study was to determine whether it is feasible to obtain good-quality images with anterior segment OCT (AS-OCT) in patients with episcleral or scleral inflammation located anterior to the equator, and whether this technique is able to...

Choroidal and RNFL thickness in patients with OSAS

In obstructive sleep apnoea syndrome (OSAS), hypoxia secondary to repetitive apnoeic episodes leads to blood pressure variations and haemodynamic changes. There is also intermittent activation of the sympathetic system when the patient is aroused from sleep during apnoeic episodes. OSAS...

Intracameral mydriasis with Mydrane

The aim of this study is to evaluate the ‘real world’ experience in a UK setting for intracameral Mydrane mydriasis in routine cataract surgery. A prospective consecutive series of 60 patients (group 2) had intraoperative, intracameral Mydrane (tropicamide 0.02%, phenylephrine...

Cavernous sinus thrombosis and orbital cellulitis

This is a report of six cases of combined orbital cellulitis and infective cavernous sinus thrombosis, with a literature review. The average age was 39 years, four were male and two were intravenous drug users. All had sinusitis, usually involving...

Oral glycerol effect on anterior chamber depth during cataract surgery

The authors present the findings of a controlled clinical trial where cataract patients having surgery for both eyes at least seven days apart were given oral glycerol preoperatively when operating on the right eye. This meant that the left eye...

Quantum imaging research could improve retinal scans

New EU-funded feasibility project is testing a quantum approach that could reveal finer detail in the eye than ever before. A European research consortium is exploring a new quantum imaging technique that could one day help clinicians see the earliest...

Large-scale study uncovers demographic and sex factors behind genetic cause of age-related visual loss

A new study has identified a major genetic contributor to Fuchs’ Endothelial Corneal Dystrophy (FECD), a common cause of vision loss, also highlighting the significant roles of sex and ancestry. FECD is a common, inherited eye condition that primarily affects...

Effects of phacoemulsification on IOP and drug use in glaucoma

For patients with comorbid cataract and primary open-angle glaucoma (POAG), guidance is lacking as to whether cataract extraction and traditional filtering surgery should be performed as a staged or combined procedure. Achieving this guidance requires an evidence-based understanding of the...

RAPD in glaucoma screening

A study was conducted to investigate the relative afferent pupillary defect (RAPD) by swinging flashlight as a potentially useful screening test for glaucomatous optic neuropathy. The authors recruited 107 subjects with or without glaucoma from a clinic population. A medical...
