PURPOSE: Lacosamide (LCM) was recently introduced in the Middle East. The aim of this study was to evaluate the safety, tolerability, and efficacy of LCM in patients with focal onset seizures and determine if our results are comparable with those derived from Western countries. METHODS: This is a retrospective analysis from two medical centers on consecutive patients diagnosed as having focal onset seizures and treated with add-on LCM. The primary efficacy variables were the 50% responder and seizure-free rates, and the secondary outcome variables included the percentages of patients who achieved seizure remission during the last 6-month follow-up period and the percentages of discontinuation due to lack of efficacy or tolerability...

PURPOSE: Eccentric photorefraction and Purkinje image tracking are used to estimate refractive state and eye position simultaneously. Beyond vision screening, they provide insight into typical and atypical visual development. Systematic analysis of the effect of refractive error and spectacles on photorefraction data is needed to gauge the accuracy and precision of the technique. METHODS: Simulation of two-dimensional, double-pass eccentric photorefraction was performed (Zemax)...

Convolutional Neural Networks have been proposed as suitable frameworks to model biological vision. Some of these artificial networks showed representational properties that rival primate performances in object recognition. In this paper we explore how color is encoded in a trained artificial network. It is performed by estimating a color selectivity index for each neuron, which allows us to describe the neuron activity to a color input stimuli. The index allows us to classify whether they are color selective or not and if they are of a single or double color...

We present a 43-old-male who suffered from a slowly progressive loss of vision in the left eye. Magnetic resonance (MR) imaging revealed a well-circumscribed contrast-enhancing lesion in the region of the anterior cavernous sinus and superior orbital fissure that extended into the optic canal. A schwannoma or meningioma was suspected. A transcranial surgery performed at another institution was not successful in removing the tumor and further deterioration of vision occurred. After resection of the left middle turbinate, the sphenoid and maxillary sinus were opened...

BACKGROUND: Wernekink commissure syndrome causes a peculiar combination of internuclear ophthalmoplegia, dysarthria, and delayed-onset palatal myoclonus. Palatal myoclonus is thought to be secondary to delayed hypertrophic degeneration of the bilateral inferior olivary nuclei secondary to involvement of bilateral dentatoolivary tract. We describe a case of a patient with early-onset palatal myoclonus. CASE PRESENTATION: A 53-year-old Caucasian man with several vascular risk factors presented to our emergency room with slurred speech, double vision, difficulty with swallowing and walking, and rhythmic contractions of the soft palate...

BACKGROUND: Pancreatic cysts are being diagnosed more frequently because of the increasing usage of imaging techniques. A pseudocyst with the major diameter of 10 cm is termed as a giant cyst. Asymptomatic pseudo-cysts up to 6 cm in diameter can be safely observed and monitored without intervention, but larger and symptomatic pseudocysts require intervention. CASE PRESENTATION: A 27-year-old Sri Lankan male, with history of heavy alcohol use, presented with progressive abdominal distension following an episode of acute pancreatitis...

AIM: To estimate the prevalence of glaucoma in Australia. METHODS: This was a population-based study of 3098 non-Indigenous Australians (50-98 years) and 1738 Indigenous Australians (40-92 years) stratified by remoteness. Each participant underwent a standard examination that included visual field assessment, tonometry and non-mydriatic fundus photography. Two fellowship-trained glaucoma specialists independently assessed relevant case notes (past ocular history, best-corrected visual acuity, frequency doubling technology visual fields, Van Herick grade, intraocular pressure and optic disc-centred photographs) and assigned a diagnosis ranked on a scale of certainty: none, possible, probable or definite glaucoma...

Background: Past studies using the Bonn Scale for the Assessment of Basic Symptoms (hereafter, Bonn Scale) have shown that self-reported perceptual/cognitive disturbances reveal which persons have or will soon develop schizophrenia. Here, we focused specifically on the clinical value of self-reported visual perceptual abnormalities (VPAs) since they are underexplored and have been associated with suicidal ideation, negative symptoms, and objective visual dysfunction. Method: Using the 17 Bonn Scale vision items, we cross-sectionally investigated lifetime occurrence of VPAs in 21 first-episode psychosis and 22 chronic schizophrenia/schizoaffective disorder (SZ/SA) patients...

Perceptual learning (PL) has been traditionally thought of as highly specific to stimulus properties, task and retinotopic position. This view is being progressively challenged, with accumulating evidence that learning can generalize (transfer) across various parameters under certain conditions. For example, retinotopic specificity can be diminished when the proportion of easy to hard trials is high, such as when multiple short staircases, instead of a single long one, are used during training. To date, there is a paucity of mechanistic explanations of what conditions affect transfer of learning...

Dry eye is defined by a tear film instability resulting in variable but systematic fluctuations in the quality of vision. Variability in optical quality can be demonstrated using a double pass aberrometer such as the OQAS (Optical Quality Analyzing System, Visiometrics). The goal of this work is to compare fluctuations in objective quality of vision measured by OQAS between treatment with normal saline eye drops and treatment with carmellose 0.5% and hyaluronic acid 0.1% (Optive Fusion [OF], Allergan) in patients with moderate dry eye syndrome...
