Aim: By reviewing the existing clinical studies about visual snow (VS) as a symptom or as part of visual snow syndrome (VSS), we aim at improving our understanding of VSS being a network disorder. Background: Patients with VSS suffer from a continuous visual disturbance resembling the view of a badly tuned analog television (i.e., VS) and other visual, as well as non-visual symptoms. These symptoms can persist over years and often strongly impact the quality of life. The exact prevalence is still unknown, but up to 2...

The most common approaches in the treatment of epilepsy, the trans-sylvian selective amygdalohippocampectomy (SAH) and the anterior temporal lobe resection (ATLR) reach the medial temporal lobe through different surgical routes. Our aim was to delineate the white matter (WM) fiber tracts at risk in relation to trans-sylvian SAH and ATLR by defining each fascicle en route to medial temporal lobe during each approach. ATLR and trans-sylvian SAH were performedand related WM tracts en route to medial temporal region were presented in relation to the relevant approaches and surrounding neurovascular structures...

CME/Answers: Pituitary Incidentaloma in Adults: Key Knowledge for the General Practice Abstract. Incidentally detected pituitary masses, so-called pituitary incidentalomas, are increasing in frequency as the frequency of performing imaging increases. Evaluation of the imaging from a trained neuroradiologist as well as additional endocrinological and, if necessary, neuroophtalmological studies are part of the initial assessment that drives the treatment decision: in the case of benign small lesions with unremarkable assessment results, follow-up is indicated, whereas potentially malignant lesions or lesions with endocrinological or neuroophtalmological irregularities are usually treated...

BACKGROUND: Despite the broad category of differentials for sellar region, most of them present with similar clinical signs and symptoms. Headache and visual disturbance are among the frequently seen as presenting symptom. Visual field (VF) assessment is one of the crucial component of neuroophtalmologic assessment and mean deviation (MD) value from automated perimetry allows quantification of the visual field defect. We formulated a study to look into the factors that affect the visual field outcome after surgery...

UNLABELLED: The aim of the study was to evaluate the effectiveness of individually tailored anodal tDCs/ neurofeedback protocol for the reduction of post-operative depression after a neuroophtalmological operation of the meningioma. The neuromarkers in Quantitative EEG (QEEG) and Event-related potentials (ERPs) were utilized in the construction of protocol and evaluation. CASE DESCRIPTION: A 45-year-old female after successful neuro-ophthalmic surgery of the meningioma, complained of severe pain and anxiety, difficulties with sleeping, attention and memory problems, as well as inability to continue working in her given profession...

AIM: Mitochondrial (mt) disorders are metabolic conditions with multiorgan involvement, which often cause neuroophtalmological symptoms. The aim of the study was to investigate the relation between progressive external ophthalmoplegia (PEO), visual pathway and mitochondrial DNA (mtDNA) mutations in patients younger than 55 years of age. METHODS: Five female patients (35 to 53 years of age) with mithochondrial disease were investigated. Automated threshold perimetry (Octopus G2 test), scanning laser polarimetry (GDx-VCC and GDx-ECC) and Fourier-domain optical coherence tomography (RTVue-100 OCT) were used in addition to detailed ophthalmological examination and evaluation of visually evoked potentials (VEP)...

Adam Bednarski (1869-1941). Prominent Polish ophthalmologist, a student of professor Wiktor Bolesław Wicherkiewicz. A professor and the head of the department of ophthalmology in Lviv. The author of about 50 works in ophthalmology and the history of medicine, published in Polish, German, and French. He prepared the first study of the history of Polish ophthalmology from the 13th to the18th century. He also studied the history of the use of herbs in medicine; on the basis of the old herbaria he described the herbal treatment and remedies in the 16th and 17th centuries...

OBJECTIVE: To assess the effect of hormone replacement therapy on neural transmission in postmenopausal women using tibolone by a non-invasive, objective way. STUDY DESIGN: In a randomised, 3 cycle, placebo-controlled study, neurovisual transmission in optic pathways were evaluated by measuring visual evoked potentials (VEP). After neuroophtalmologic examination, eligible subjects were randomised into two groups. Treatment group (n=38) were given tibolone 2.5mg daily continuously for 3 months and control group (n=20) were treated with placebo...

In a 32 year old woman harboring a macroprolactinoma with supra and laterosellar extension, bromocriptine was able to reduce the size of the tumor and the very high circulating levels of prolactin, restoring ovulatory menstrual cycles. At the 8th week of a not recommended pregnancy, the patient presented bitemporal superior quadrantopsia and headache. After reinstitution of bromocriptine therapy the woman showed a rapid improvement of neuroophtalmological complications. The treatment was continued till the delivery; a normal baby was born...

The authors evaluate the intracavital treatment with 90 Yttrium silicate colloid given in 31 occasion in 26 patients of cystic craniopharyngioma. The method has been applied since 1975 in the National Institute of Neurosurgery Budapest, using practically the same method as described by Backlund et al. (1972). Although the intracavital treatment was only one among several applied forms of treatment (resection, aspiration, shunting etc.) the effectiveness of the internal irradiation is obvious. The main effect is shrinkage of the cyst...
