Mechanism of colour vision involvement in multiple sclerosis
There is evidence to show that the optic nerve and retina are affected in multiple sclerosis (MS) even without any clinical evidence or history of optic neuritis (ON). MS without optic neuritis causes colour-vision deficit, however, the evidence for selective...
Likelihood of developing multiple sclerosis after optic neuritis diagnosis
Optic neuritis (ON) is a relatively common cause of acute optic neuropathy in young patients which often presents as the first sign of multiple sclerosis (MS). There is a lack of evidence around the factors that are associated with the...
Normative reference values for optic nerve sheath diameter in children
The purpose of this study was to measure optic nerve sheath diameter (ONSD) in paediatric patients without pathology using brain CT performed for various reasons and to provide normal tomographic reference values. This was a retrospective study of CT scans...Understanding spaceflight-associated neuro-ocular syndrome (SANS): what do we know?
Introduction Formerly known as visual impairment and intracranial pressure syndrome (VIIP), space-related neuro-ocular syndrome (SANS) is defined by a collection of ophthalmic and neurological findings in astronauts after long-term spaceflight [1]. Changes in the eyeball, such as hyperopic shift, during...Revealed: The growing crisis of workplace-related eye injuries
Nearly half of UK workers believe their job puts their eye health at risk, yet are businesses overlooking this critical issue? New survey findings commissioned by NuVision Biotherapies highlight a rising yet often ignored concern in workplace health; eye injuries...
Multimodal Retinal Imaging
Understanding of rapidly advancing retinal imaging techniques is important as they have changed the management of retinal conditions considerably. Interpretation of these tests is a vital skill in the armamentarium of every practising ophthalmologist. The book is directed at general...
Using optical coherence tomography angiography to detect MoyaMoya vasculopathy
Moyamoya (MM) disease is a chronic cerebrovascular disease that can lead to progressive stenosis of the terminal portions of the internal carotid arteries and their proximal branches. The authors carried out a cross-sectional cohort study to investigate vascular changes in...Semaglutide and vision loss: A new concern for NAION risk?
This article has been verified for CPD. Click the button below to answer a few short questions and download a form to be included in your CPD folder. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have emerged as transformative agents in...The role of spectral-domain OCT RNFL in revealing a pituitary adenoma with atypical visual fields
Pituitary adenomas classically cause bitemporal hemianopia by compressing the optic chiasm. However, in some cases, the pattern of visual field loss may be atypical and mimic homonymous hemianopia, depending on the direction and extent of tumour expansion. Spectral-domain optical coherence...
Beware the disc in myopic patients
Glaucoma is a chronic and progressive optic neuropathy characterised by damage of retinal ganglion cells. Evaluation of structural damage of the optic nerve is important in glaucoma diagnosis. The ISNT rule states that the neuroretinal rim width is generally widest...
Primary visual pathway changes in individuals with chronic mild traumatic brain injury
Patients with mild traumatic brain injury (mTBI) often self-report vision disturbance despite showing no reduction of visual acuity or fundus examination abnormality. This prospective, observational, cross-sectional study aimed to determine if using a sweeping array of investigations can help diagnose...
