DTI/MRI results in amblyopia

Diffusion tensor imaging (DTI) is an MRI technique that can evaluate white matter integrity and neuronal connectivity. Normal brain maturation and myelination are associated with reduced water diffusion and increased diffusion anisotropy. The authors aimed to evaluate the anterior optic...

MRI characteristics of NMO, MOG and MS-related ON

This review article examined differences of MRI appearances that can help clinicians assess and manage these important neuro-ophthalmic disorders. It also examined the role of optic nerve MRI as a prognostic indicator in acute optic neuritis (ON). The major findings...

MRI in anisometropic amblyopia

This study recruited patients with anisometropic amblyopia in the right eye and without strabismus. This allowed the authors to reduce the effort exerted in cortex activities by different amblyopic eyes. They used whole brain analysis to find the differences between...

Using MRI to assess normal variation in optic chiasm anatomy

The authors present an MRI study including 61 MRI scans using a 1.5 T with slice thickness of 1 or 5mm and the sequence showing the highest resolution of the chiasm. A predetermined set of measurements were taken in a...

Early diagnosis of pituitary apoplexy using combined MRI findings

The author presents a literature review searching the terms ‘pituitary ring sign’ and ‘sphenoid sinus mucosal thickening’ in the context of pituitary apoplexy from 1990 until the present day. These two findings are both magnetic resonance imaging (MRI) signs of...

Aspheric toric IOL implantation and LRI in eyes with cataracts and astigmatism

This is a prospective study from a single unit to compare the visual outcome of aspheric toric intraocular lens (IOL) implantation and limbal relaxing incisions (LRI) for management of coexisting age-related cataracts and astigmatism. Sixty eyes of 60 patients with...

A novel way to diagnose optic neuropathies using Bruch’s membrane opening

Differential diagnosis of optic neuropathies can be challenging but is crucial for the correct management of the underlying disease and prevention of further damage. Bruch’s membrane opening (BMO) was recently discovered as the anatomical border of the optic disc. BMO...

A case of progressive supranuclear palsy-like syndrome following aortic aneurysm repair

This original article illustrates the case of an 18-year-old woman who developed progressive supranuclear palsy-like syndrome following an uneventful aortic aneurysm repair. The patient was unaffected for the first 48 hours after surgery and then developed dysarthria, dysphagia (requiring a...

Morning glory syndrome associated with PHPV

This is a retrospective review of the medical records of 85 eyes / 74 patients diagnosed as morning glory syndrome (MGS) in the clinic between November 2009 and November 2012. Twenty two eyes of 19 patients diagnosed as having MGS...

An unusual case report of bilateral abducens paralysis

In this case report a nine-year-old girl develops bilateral abducens nerve paralysis, caused by vertebrobasilar dolichoectasia. Vertebrobasilar dolichoectasia is characterised by dilation, tortuosity and marked elongation of the vertebral and basilar arteries. Clinical findings result from the compression and displacement...

Test combination which could detect prodromal Alzheimer disease

The authors prospectively recruited a convenience sample of individuals aged over 65 and either with a diagnosis of mild cognitive impairment (MCI) due to Alzheimer disease or normal cognition. Other types of dementia and severe neurological conditions were excluded. All...

Retinotopic fMRI reveals visual dysfunction and functional reorganisation in the visual cortex of glaucoma patients

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...
