Abducens, cranial nerve, microvascular ischaemia, oculomoto, trochlear
Patients aged over 50 presenting with isolated nerve palsies of the third (pupil sparring), fourth or sixth nerves, are often described as having microvascular extraocular palsies. This review looks critically at the evidence surrounding these microvascular non-arteritic extraocular palsies and...

Adjustable suture, cranial nerve palsy, diplopia, strabismus, third nerve palsy
The authors of this article explore the factors associated with successful surgical outcomes in third nerve palsy, which is known to be difficult to treat. A number of case notes were reviewed for patients who underwent surgery or botulinum toxin...

Migraine, retinal nerve fibre layer thickness, spectral-domain optical coherence tomography
Migraine is a common, chronic, multifactorial neuro-vascular disorder typically characterised by recurrent attacks of disabling headache and autonomic nervous system dysfunction (migraine without aura). Up to one third of patients also have neurological aura symptoms (migraine with aura). The objective...
Long-term retinal changes following unilateral retrobulbar optic neuritis

OCT, optic neuritis, optical coherence tomography, RNFL, steroid
The aim of this study was to assess the longitudinal changes in retinal nerve fibre layer (RNFL) thickness after a first attack of optic neuritis and to investigate the impact of treatment on RNFL thinning at one year after the...

Adult optic glioma, ganglioglioma, pilocytic astrocytoma, WHO Grade I–II
Primary optic nerve gliomas are most commonly benign and occurring in childhood. Malignant optic gliomas occur in adulthood and follow an aggressive course usually leading to blindness and death within months. This paper describes the clinical and histopathological features of...

Idiopathic intracranial hypertension, lumboperitoneal shunt, ventriculoperitoneal shunt, visual fields
The authors of this paper reviewed patient case notes to determine visual outcome following shunt surgery for idiopathic intracranial hypertension (IIH). A retrospective case notes review was conducted for 50 patients who underwent shunt surgery for IIH. Outcome measures included...

Adjustable suture, cranial nerve palsy, hummelsheim, paralytic strabismus, sixth nerve palsy
The aim of the study was to identify factors associated with surgical outcomes in isolated abducens palsy. To achieve this goal the authors reviewed the records of adult patients with abducens palsy who underwent strabismus procedures during a fourteen year...
Abducens nerve palsy following surgical correction of craniosynostosis

Abducens nerve palsy, distraction osteogenesis, expansion cranioplasty
The authors present two cases of unilateral abducens palsy secondary to a recent trans-sutural distraction osteogenesis (TSuDO) operation for craniosynostosis. The basic principle of the TSuDO procedure is described as dissection and distraction of the prematurely fused sutures. This complication...

functional visual field loss, optic nerve, perimetry, visual fields
Functional visual field loss is traditionally assessed by kinetic perimetry, typically producing spiralling isopters. This study looked at the spatial distributions of functional field deficits using automated static perimetry. A retrospective review of automated perimetry records was conducted using a...

Binocular summation, dark adaptation, monocular vision, neural summation, probability summation
Previous studies have reported conflicting results on the existence of binocular enhancement of dark vision. This study compares monocular and binocular absolute thresholds of dark adaptation in two different populations (healthy individuals and those with chronic respiratory insufficiency). The study...
