BACKGROUND: Primary intracranial anaplastic gangliogliomas are rare tumors in the pediatric patient group. Most of them present with symptoms of elevated pressure or symptomatic epilepsy. Extraaxial location is far more common than axial location. On MRI examination, they mimic pilocytic astrocytomas. The outcome after surgery depends mainly on the possible amount of surgical resection, and oncological therapy is necessary to prevent recurrence of the disease. CASE REPORT: An 11-year-old boy presented with headache and double vision due to obstructive hydrocephalus...

BACKGROUND: We present a unique case of a patient who suffered two rare events affecting the supranuclear control, first of the vertical and second of the horizontal eye movements. The first event involved bilateral thalamic infarcts that resulted in double depressor palsy. The second event occurred 1 year later and it involved supranuclear control of horizontal eye movements creating pursuit deficit. CASE PRESENTATION: A 47-year-old male presented with complaints of diplopia upon awakening...

A hypertensive patient presented with complaints of headache and fluctuating double vision and deterioration in vision from 2010. She displayed symptoms associated with convergence spasms, which could be confused with sixth cranial nerve palsies. A few pointers are given to prevent clinicians from being caught off-guard when encountering this clinical condition.

Guang Deng
Edge-aware smoothing has been extensively studied due to its wide range of applications in computer vision and graphics.Most published works have been focused on formulating the smoothing problem in the spatial domain. In this paper, we propose a new edge-aware smoothing framework called guided wavelet shrinkage (GWS) which is formulated in the wavelet domain as a maximum a posterior estimation problem. We impose a number of desirable properties on the statistical models and the associated parameters in order to derive an effective and computationally efficient algorithm...

BACKGROUND: Ocular herpes is a viral infection of the eye caused by the herpes simplex virus (HSV), a double-stranded DNA virus. Corneal scarring caused by herpes simplex keratitis (HSK) is the leading infectious cause of penetrating corneal graft in high-income countries. Acyclovir is an antiviral drug known to have a protective effect against recurrences in herpetic eye disease. While there are some studies which have evaluated the effects of intervention with oral antiviral in preventing such recurrences in people with corneal grafts, a systematic review of all comparative clinical trials has not been previously undertaken...

To identify and localize an intraorbital wooden foreign body is often a challenging radiological issue; delayed diagnosis can lead to serious adverse complications. Preliminary radiographic interpretations are often integrated with computed tomography and magnetic resonance, which play a crucial role in reaching the correct definitive diagnosis. We report on a 40 years old male complaining of pain in the right orbit referred to our hospital for evaluation of eyeball pain and double vision with an unclear clinical history...

REVIEW
Claudia F E Kirsch, Karen Black
When patients see double with both eyes open, known as "binocular diplopia," this may be a harbinger of underlying life-threatening causes. This article presents pertinent anatomy, critical abnormality, and radiographic features that should be double checked for in diplopia. Key areas requiring a double check using the acronym VISION include Vascular, Infectious and Inflammatory, the Scalp for giant cell arteritis, Sphenoid and Skull base in trauma, Increased intracranial pressure (pseudotumor cerebri), Onset of new headaches or psychosis, and Neoplasm...

A full-length complementary (c)DNA encoding ultraviolet (UV)-sensitive opsin (sws1) was isolated from the retina of the Japanese sardine Sardinops melanostictus. The sws1 phylogenetic tree showed a sister group relationship with the Cypriniformes, following the ray-finned fish phylogeny. By expressing reconstituted opsin in vitro, it was determined that the maximum absorbance spectrum (λmax ) of sws1 is around 382 nm, being intermediate in position between two subtypes of sws1 pigment that are UV sensitive (λmax  = 355-380 nm) and violet sensitive (λmax  = 388-455 nm), which have been reported to date...

PURPOSE: In childhood intermittent XT, the frequency and type of symptoms have not been rigorously studied. We aimed to identify specific symptoms in children with intermittent XT, their frequency, and effects on health-related quality of life (HRQOL). METHODS: 35 children (5-13 years) with intermittent XT without previous surgery were enrolled in a prospective cohort study. Specific symptoms were identified from a previous study involving child and parent interviews and formulated as a 22-item symptom questionnaire...

The distinct behaviors and varied habitats where animals live place different requirements on their visual systems. A trade-off exists between resolution and sensitivity, with these properties varying across the retina. Spectral sensitivity, which affects both achromatic and chromatic (colour) vision, also varies across the retina, though the function of this inhomogeneity is less clear. We previously demonstrated spatially varying spectral sensitivity of double cones in the cichlid fish Metriaclima zebra due to coexpression of different opsins...

PURPOSE: The visual performance of monofocal, bifocal, and trifocal intraocular lenses was evaluated by human individuals using a vision simulator device. This allowed investigation of the visual impression after cataract surgery, without the need actually to implant the lenses. METHODS: The randomized, double-masked, three-way cross-over study was conducted on 60 healthy male and female subjects aged between 18 and 35 years. Visual acuity (Early Treatment Diabetic Retinopathy Study; ETDRS) and contrast sensitivity tests (Pelli-Robson) under different lighting conditions (luminosities from 0...

BACKGROUND: Amblyopia is a common neurodevelopmental disorder of vision that is characterised by visual impairment in one eye and compromised binocular visual function. Existing evidence-based treatments for children include patching the nonamblyopic eye to encourage use of the amblyopic eye. Currently there are no widely accepted treatments available for adults with amblyopia. The aim of this trial is to assess the efficacy of a new binocular, videogame-based treatment for amblyopia in older children and adults...

Building on long-term benefits of early intervention (Paper 2 of this Series) and increasing commitment to early childhood development (Paper 1 of this Series), scaled up support for the youngest children is essential to improving health, human capital, and wellbeing across the life course. In this third paper, new analyses show that the burden of poor development is higher than estimated, taking into account additional risk factors. National programmes are needed. Greater political prioritisation is core to scale-up, as are policies that afford families time and financial resources to provide nurturing care for young children...
