Transient visual loss caused by crowded optic discs
The author presents four cases of transient visual loss (TVL) in young females (age range at presentation 14-22 years) with crowded optic discs. Patient demographics, investigations, medical and social histories are provided for all patients. A review of evidence for...
Assessment of slow and fast vergence in stroke survivors
The authors present the findings of a prospective cohort study. Three hundred and five stroke survivors were recruited consecutively. The following exclusion criteria were applied; aphasia, cognitive impairment, visual inattention, ocular motor nerve palsy and neuromuscular disease. Fifty age-matched controls...
Screening for visual processing deficits in dementia
The Queen Square Screening test for Visual Deficits (QS test) screens for changes in visual processing. It has never been formally validated as a single test. The test consists of a short booklet developed using remnant object and spatial perception...
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...
Where along the vergence pathway is affected by Parkinson’s Disease?
The authors outlined three hypothesis for the effect Parkinson’s Disease has on blur- and disparity-driven vergence with reference to location within the vergence system that is affected to be tested in this prospective study. The study recruited 14 participants with...
G-CSF intravitreal injections for NAION: a pilot study
In rodent models with anterior ischemic optic neuropathy (AION), granulocyte colony-stimulating factor (G-CSF) confers a neuroprotective effect on retinal ganglion cells (RGCs) via anti-apoptotic and anti-inflammatory processes. This prospective study investigated the efficacy of intravitreal injection of G-CSF for the...
Long-term use of botulinum toxin for hemifacial spasm and blepharospasm
The authors conducted a retrospective review of clinical / procedure documentation for consecutive blepharospasm (BEB) and hemifacial spasm (HFS) patients undergoing treatment with onabotulinum toxin A (Botox) in one clinic setting over the past 20 years. They report on the...
Case reports of ‘ictal lid saccades’ and ‘ictal blinks’
The authors present two cases of lid movements with discrete physiology and propose the terms ‘ictal lid saccades’ and ‘ictal blink’ to describe the movements seen. These two types of lid movement, blinks and saccades, have discrete kinematic properties and...
Lagophthalmos as a potential complication of COVID-19
Lagophthalmos is a condition associated with the inability to close the eyelids effectively, with the main cause being facial nerve palsy. The authors aimed to investigate whether lagophthalmos was associated with coronavirus infection (COVID-19) by comparing patients diagnosed with lagophthalmos...
A survey of neuro-ophthalmologists on use of corticosteroids in giant cell arteritis
While corticosteroids are the mainstay of treatment in giant cell arteritis (GCA), the type, dose, route and duration of treatment remains controversial. The authors surveyed 180 neuro-ophthalmologists on their use of this treatment via email in a two-month period. Results...
A retrospective medical notes review in patients with poor vision due to NAION
Very severe visual loss (hand movements or less) is typical of arteritic anterior ischaemic optic neuropathy (AION) and relatively rare in non-arteritic AION (NAION). This study aimed to report the frequency of very poor visual acuity (VA) in NAION. The...
Long-standing flattening effects on the globe following spaceflight
Posterior globe flattening has been well-documented in astronauts both during and after long-duration spaceflight (LDSF). This globe flattening is thought to be due to the disc centred anterior forces created by elevated volume and / or pressure within the optic...
