Using a driving simulator to explore the effect of visual field loss from optic disc drusen

The purpose of this study was to compare driving simulator performance of participants with visual field loss (VFL) from optic disc drusen (ODD) with a normally sighted control group and a group of individuals with glaucoma. Data on performance and...

Metamorphopsia in idiopathic epiretinal membranes

The Amsler grid is commonly used for self-monitoring, but is qualitative and has low sensitivity. The M-chart reduces the amount of spatial redundancy (‘filling in’) in the Amsler grid. The Orientation Discrimination (OD) test studied in this paper consists of...

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...

Disc margin delineation using spectral domain OCT

Observing progressive anatomical changes of the optic nerve head is essential in the detection of progression in glaucoma. Imaging devices continue to evolve and are useful in detecting change in established glaucoma, although probably less useful in an initial diagnosis....

Differences in elastometry of cornea and optic nerve head in both eyes of patients with NAION

Non-arteritic anterior ischaemic optic neuropathy (NAION) is an important cause of visual loss in the middle aged and elderly population. This prospective cross-sectional study investigates the biomechanical properties of optic nerve head (ONH) and cornea in both eyes of patients...

Optic disc pit maculopathy: an optical coherence tomography study

This was a single-centre, retrospective observational case series that aimed to analyse the change of optical coherence tomography (OCT) characteristics in the natural course of optic disc pit maculopathy (ODP-M) and their effects on visual acuity. Twenty-two eyes of 22...

Clinical predictors of proliferative sickle cell retinopathy

Sickle Cell Disease (SCD) is an inherited disorder resulting in production of Haemoglobin S (HbS), which aggregates in conditions of hypoxia, acidosis or hyperosmolarity. This leads to vascular stasis, thrombosis and ischaemia. The authors present a cross-sectional study (45 consecutive...

Effect of preservative free fluoroquinolones on human corneal epithelial cells in vitro

Fluoroquinolones, including second generation (ofloxacin and ciprofloxacin), third generation (levofloxacin and tosufloxacin) and fourth generation (gatifloxacin and moxifloxacin), are a group of bactericidal agents used to treat multiple ocular infections. The third and fourth generation fluoroquinolones have enhanced Gram-positive activity...

Review of non-arteritic anterior ischaemic optic neuropathy

This article reviews the risk factors, clinical presentation and therapies that have been investigated for non-arteritic anterior ischaemic optic neuropathy (NAAION). Additionally, it provides an update from recent rodent and primate models, offering a new insight into the pathophysiology of...

Correlation between structural and functional status of optic nerve and retina in multiple sclerosis

Multiple sclerosis (MS) involves autoimmune inflammatory demyelination and axonal degeneration in the central nervous system. Investigation of the retina and optic nerve head (ONH) is an ideal way to visualise this demyelination. This study investigates the functional and structural properties...

A round-up of the eye-related hot topics that have been trending on social media over the last few weeks. #whoopigoldberg #presbyopia #bionic Whoopi Goldberg made a name for herself in blockbusters such as the Oscar-winning Ghost and Sister Act. She...

Non-arteritic anterior ischaemic optic neuropathy (NA-AION): a review

Ischaemic optic neuropathy (ION) is the commonest adult optic neuropathy encountered today in our ageing population, is a common cause of irreversible visual loss and is usually associated with underlying vascular disease. The condition is classified as follows: (a) Anterior...
