Effect of syringe-filling technique and risk for endophthalmitis after intravitreal injection of anti-VEGF agents

In this retrospective study the authors compare the risk for post-injection endophthalmitis between different anti-vascular endothelial growth factor (VEGF) agents and syringe preparation technique. This multicentre study included 197,402 injections. The drugs included in this study were three Anti-VEGF agents...

Intravitreal injection related endophthalmitis

This article reviews the incidence, clinical findings, risk factors, management and visual outcomes in intravitreal injection related endophthalmitis. Incidence of this complication is reported to be in the range of 0.038% to 0.065% (1 in 2000-3000 injections). Patients present typically...

New mouse model of diabetes mellitus

Diabetic retinopathy (DR) is a serious complication of diabetes. It is driven by the loss of pericytes, cells which control vascular function, due to excess formation of sugar alcohols by the enzyme aldose reductase (AR). AR has been shown to...

The Retinal Atlas (2nd Edition)

Those readers familiar with the first edition of The Retinal Atlas will appreciate the comprehensive nature of this publication, and this latest version incorporates retinal images generated by recently developed imaging technology. As the title suggests, this hardcover version is...

Data update for leading causes of CVI in England and Wales

In this article the authors present an epidemiological update, based on certifiable visual impairment (CVI) registration for figures for sight impairment (SI) in England and Wales from the last report of 2007-2008 to the current data for April 2012 to...

Transfected RPE cells inhibit AMD in rats

Age-related macular degeneration (AMD) is a leading cause of blindness in the elderly. Wet AMD is characterised by choroidal neovascularisation, new vessels into the retina, leading to leakage and tissue damage. Many proangiogenic factors particularly vascular endothelial growth factor (VEGF)...

The choroid in pregnancy

During pregnancy there can be different types of ocular changes including a decrease in corneal sensitivity, increase in central corneal thickness and curvature, decrease in intraocular pressure, central serous chorioretinopathy and ocular blood flow. Advances in ophthalmic imaging devices has...

Contrast sensitivity in myopic eyes

A classification system has been proposed for myopic maculopathy: grade 0 (no myopic retinal lesions), grade 1 (tessellated fundus), grade 2 (diffuse chorioretinal atrophy (CRA)), grade 3 (patchy CRA), and grade 4 (macular atrophy). Tessellated fundus is defined as the...

Multimodal imaging in wet AMD

This novel study set out to determine grader agreement levels of various retinal imaging techniques, commonly used in the diagnosis of wet age-related macular degeneration (AMD). Images from 52 eyes were by examined by two different observers. All images were...

Cataract surgery in patients being treated for neovascular AMD

This retrospective matched case control study evaluated outcomes and predictive factors of visual acuity (VA) change after cataract surgery in patients being treated for neovascular age related macular degeneration (nAMD). They compared 124 patients that had cataract surgery with 372...

Delayed angle closure in pseudophakia and repeated intravitreal therapy

The authors report two cases of acute angle closure many years after uneventful cataract surgery and posterior chamber intraocular lens (IOL) implantation. Both patients had neovascular age-related macular degeneration (AMD) and received regular intravitreal injections (24 and 25 injections in...

21st Century retinal laser treatment in the anti-VEGF era

In today’s world, macular laser treatment has a vital role in the treatment of diabetic macular oedema (DMO). DMO is one of the most common causes of visual impairment. Despite expensive intravitreal treatment courses of anti-VEGF, many will agree that...
