Idiopathic intracranial hypertension (IIH) is characterised by elevated intracranial pressure (ICP), which leads to optic nerve head swelling and a risk of visual loss. The impact of straining and exercise on ICP regulation is poorly understood yet clinically relevant to...

EYE - Neuro-ophthalmology
The authors present a case series of individuals referred to an electroretinography (ERG) lab for assessment due to abnormal vision symptoms, over a two year period. Cases with visual snow syndrome (VSS) or isolated visual snow (VS) were included. All...

EYE - Neuro-ophthalmology
Giant cell arteritis (GCA) is the most common systemic vasculitis in older people and can cause devastating sight loss if untreated. Temporal artery biopsy is often relied upon for diagnosis by ophthalmologists, with a positive biopsy result indicating whether the...

Cerebral vasomotor reactivity, breath-holding index, diabetes mellitus, diabetic retinopathy, transcranial Doppler ultrasound
Cerebral micro-angiopathy caused by diabetes can manifest itself as an impairment in cerebrovascular reactivity. Transcranial doppler ultrasound (TCD) is a cost-effective and non-invasive way to measure the cerebrovascular reactivity. This study aimed to assess the relationship between the grade of...

Occult, differentiating, neuroretinitis, non-arteritic anterior ischaemic optic neuropathy, optical coherence tomography
This study evaluates differences between neuroretinitis and non-arteritic anterior ischaemic optic neuropathy (NAAION) in terms of patient demographics, clinical presentation, and optical coherence tomography (OCT) findings. Medical records of patients with a final diagnosis of occult neuroretinitis or NAAION were...
