Retinotopic fMRI reveals visual dysfunction and functional reorganisation in the visual cortex of glaucoma patients

This study investigated the retinotopic functional representation in the visual cortex of mild to moderate primary open-angle glaucoma (POAG) participants and age-matched normal volunteers, using wide-view visual presentation, high-resolution retinotopic stimuli, and high-resolution blood oxygenation level dependent (BOLD) functional magnetic...

World leading ophthalmology experts join line-up at free optometry summit in Bristol

Up to 12 CPD points on offer as SpaMedica hosts its 2023 Optometry Conference at The Bristol Pavilion on 26 November.

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...

A review of chromosome 9p21 POAG susceptibility locus

Primary open angle glaucoma (POAG) is a genetically complex disease and the overall phenotype is influenced by multiple traits including intraocular pressure (IOP), central corneal thickness and structural features of the optic nerve head. Therefore, genes affecting any of these...

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...

Diagnostic accuracy of different keratoconus detection indices of pentacam in paediatric eyes

This is a retrospective study of 432 non-keratoconic eyes compared with 48 eyes with keratoconus (KC) or forme fruste KC (FFKC) in a paediatric population in Cairo, Egypt between December 2013 and October 2018. The authors discuss the rationale of...

Eye research: where next?

Eye research in the UK is underfunded relative to other areas of medical research and general awareness of sight loss and its prevention remains poor, messages that were reinforced in presentations and discussions during a recent research summit meeting in...

Timing of vitrectomy for retained lens fragments

The purpose of this study was to compare the results of same setting vitrectomy with delayed vitrectomy for retained lens fragments following cataract surgery. Same setting vitrectomy was defined as the patient not leaving the operating table following cataract surgery....

It’s not all about ARED - Time for a pragmatic approach to nutrition for eye health?

Advances in treatment for retinal diseases involving neovascularisation have undoubtedly changed the future of eye care across the UK for the better, but also created great challenges for service delivery in ophthalmology, particularly within the NHS. Some statistics are starting...

A near miss

A 55-year-old gentleman presented with a ‘blurry patch’ to his left eye which he had noticed for the past two months. The visual acuity with correction was 6/5 in the right eye and 6/6 in the left eye on the...

Examination of optic disc drusen using computer-based fundus analysis

This case-control study analysed the optic disc angioarchitecture in optic disc drusen (ODD) using computer-based fundus examination. A group of ODD patients were compared to a group of healthy controls with normal optic discs. The cohort included 30 healthy volunteers...

Reported cases of hemifield slide phenomenon

This article reports three cases of hemifield slide, a phenomenon whereby there is an inability to stabilise and fuse visual hemifields. It occurs with heteronymous visual field loss and is thought to result from the loss of corresponding retinal points....
