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, 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...

Abducens nerve palsy, carotid-cavernous fistula, transvenous embolisation
This report presents two cases of abducens palsy developing with late onset following endovascular treatment for carotid-cavernous fistula. Following this common and effective treatment for carotid-cavernous fistula, an immediate cranial nerve palsy is a common finding. It usually resolves spontaneously....

EYE - Neuro-ophthalmology
This study evaluates the choroidal and macular thickness in patients with chronic nonarteritic anterior ischaemic optic neuropathy (NA-AION). Two groups of subjects were compared, group one included 20 eyes with chronic NA-AION and group two, 31 healthy control eyes. The...

EYE - Neuro-ophthalmology
Ocular Ischaemic syndrome is a devastating eye disease caused by severe carotid stenosis. This study’s purpose was to develop a reliable rat model for this syndrome by subjecting rats to common carotid artery occlusion and sham surgery. Rats were assigned...
