Posterior circulation stroke associated demographics, risk factors and aetiology
The authors present a retrospective case notes review of patients diagnosed with homonymous hemianopia following a radiologically confirmed stroke. A total of 85 patients were identified by searching an electronic medical records system over an 11-year period. Data were extracted...
Case presentation: seizures as a presenting sign of idiopathic intracranial hypertension
Idiopathic intracranial hypertension (IIH) is a syndrome of isolated elevated intracranial pressure of unknown cause. Neurological examination in IIH is typically normal except for papilloedema and possible cranial nerve six palsy, although rare, atypical symptoms and signs can occur. With...
Is thrombolytic treatment warranted for central retinal artery occlusion?
Central retinal artery occlusion (CRAO) is a subtype of acute ischaemic stroke which results in severe visual loss. Acute CRAO is equivalent to a brain acute ischaemic stroke (AIS), as the obstruction of the central retinal artery (CRA) causes end-organ...
Is intracranial pressure affected by the valsalva manoeuvres and exercise?
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...
Transsynaptic retrograde degeneration linked to homonymous visual field loss after stroke
centre, of individuals identified with homonymous visual field loss post ischaemic stroke. Exclusion criteria were bilateral ischaemia, anterior / pregeniculate visual pathway affected and other pathology with the potential to effect visual fields. The following were extracted from the medical...
The risk factors associated with isolated microvascular third nerve palsy
The authors used the Rochester Epidemiology Project for this retrospective case review of third nerve palsy. Inclusion criteria was adults >18 years, with new onset isolated microvascular third nerve palsy diagnosed within a 36-month period, with recovery or significant improvement,...
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...
A case series of electroretinography findings in visual snow syndrome
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...
Pilot trial of Fluoxetine for post-stroke homonymous hemianopia
The authors present a pilot randomised placebo controlled double blind trial assessing 20mg fluoxetine once daily for 90 days versus placebo in stroke survivors with isolated homonymous hemianopia. Exclusion criteria were extensive in terms of pre-existing ophthalmic or neurologic disease,...
The evolution and visual prognosis of glial proliferation of different grades after macular hole surgery
This retrospective research study aimed to investigate the evolution of glial proliferation of varying grades after successful idiopathic macular hole repair and its effects on foveal microstructure and best-corrected visual acuity (BCVA). Two-hundred and two eyes were enrolled in this...
Comparison between findings in ‘active’ or ‘healed’ giant cell arteritis
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...
Referral patterns and pathways for intracranial hypertension
The authors present a retrospective case review of individuals with suspected raised intracranial pressure (ICP) over a 12-month period a single tertiary neuro-ophthalmology centre. Cases were categorised into four groups based on examination by neuro-ophthalmology; 1) referred after identification of...
