EYE - Glaucoma
This study investigated the retinotopic functional representation in the visual cortex of mild to moderate primary open-angle glaucoma (POAG) participants and age-matched normal volunteers, using wide-view visual presentation, high-resolution retinotopic stimuli, and high-resolution blood oxygenation level dependent (BOLD) functional magnetic...

Amplitude, latency, pupillary light reflex pathway, pupillometer, retrograde trans-synaptic degeneration
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...

Idiopathic intracranial hypertension, predictors, visual outcome
In this prospective study, visual outcome of 40 patients with idiopathic intracranial hypertension (IIH) was compared with clinical and neuro-ophthalmic parameters. The purpose of this was to determine any correlation to try and predict visual outcome for IIH patients. Parameters...
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...New funding will support development of wearable diagnostics for neuromuscular diseases

EYE - Glaucoma
Chronic open angle glaucoma (COAG) is the second most common cause of blindness worldwide. It is diagnosed on the basis of three clinical signs, raised intraocular pressure (IOP), visual field (VF) defects and structural changes to the optic nerve head...
