Comparison of treatment for hemianopia following stroke

The authors report the screening process and recruitment figures for a randomised controlled trial comparing interventions for post stroke homonymous hemianopia. Interventions included Fresnel prisms, visual search training and standard care (information only). Primary outcome measure was the change in...

Visual retraining for homonymous hemianopia following stroke

This is a clinical trial evaluating the efficacy of motion discrimination training as a potential therapy for stroke-induced hemianopic visual field defects involving 48 patients. They were randomised into two arms, one intervention (deficit-field) and one control (sighted-field). Patients were...

Hemianopia or visuospatial neglect: differences in information processing

It is widely reported that visuospatial neglect and hemianopia may be superimposed, and disentangling the two conditions can be pose difficulties for clinicians. The authors of this paper explored the differences in implicit information processing which is effective in patients...

Unexpected diagnoses – stroke in children and homonymous hemianopia

We present the case of a 12-year-old child presenting with a few days history of left-sided visual loss. Upon further investigation with magnetic resonance imaging (MRI) she was unexpectedly diagnosed with a right-sided chronic posterior cerebral arterial territory infarct, causing...

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,...

Using a pupillometer to confirm presence of RAPD in post stroke homonymous hemianopia

It has been reported that relative afferent pupillary defects (RAPDs) may be present in patients with occipital lobe lesions. However, a small contralateral RAPD due to a difference in the crossed and uncrossed fibres can be difficult to detect using...

Bitemporal hemianopsia as a result of ethambutol toxicity

The authors present six cases of visual loss in patients treated with ethambutol for mycobacterium avium complex, including four patients with bitemporal hemianopsia. Two additional patients were undergoing glaucoma monitoring and developed visual field defects with ethambutol treatment, which recovered...

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....

Two illustrative cases of AZOOR

The authors present two illustrative cases of acute zonal occult outer retinopathy (AZOOR) which causes acute idiopathic blind spot enlargement. The disease is characterised by sudden loss of outer retinal function associated with photopsia, with minimal or no fundoscopic changes...

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...

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...

Using bupivacaine to the medical rectus in addition to lateral rectus recession for convergence insufficiency type intermittent exotropia

This is a retrospective study of 60 paediatric optic pathway glioma (OPG) patients (NF1 or sporadic) presenting to Great Ormond Street between 2003-2017. Median follow-up was 82 months. Analysis was divided into best and worst eye vision representing level quality...
