Angle closure is usually associated with older patients, as it typically manifests in middle to later life, being associated with an age-related increased lens volume. However, angle closure can occur in any age group if there is an anatomical predisposition that promotes pupillary block or an anterior pulling of the iris. During an acute angle closure, patients generally experience ocular pain, headache, nausea, vomiting and conjunctival hyperaemia. These attacks can be misinterpreted as migraine, particularly if subacute or chronic and the demographic characteristics of the patient do not suggest a primary angle closure event...

The visual system is involved in different ways in migraine. Visual auras are the most common form of migraine aura. It may consist of positive or negative visual symptoms and cortical spreading depression is felt to be the phenomenon that underlies it. Even in migraine without aura, vision it is not totally excluded given that one of the major criteria for the diagnosis of migraine is photophobia. In persistent visual aura, patients refer symptoms defined as visual snow and television static. In retinal migraine unilateral decreased vision or complete visual loss occurs...

Recurrent painful ophthalmologic neuropathy (RPON), previously termed ophthalmoplegic migraine, is characterised by repeated attacks of one or more ocular cranial nerve palsies with ipsilateral headache. Its cause remains unclear; it is currently thought to be neuropathic in origin, but there is debate in the literature. In documented cases, a third cranial nerve palsy is by far the most common. Here we present a case of RPON involveing the fourth and sixth cranial nervesonly. Thorough investigation, including MR scan of brain and lumbar puncture, found no alternative explanation...

REVIEW
Thomas Brandt, Marianne Dieterich
Vertigo and dizziness are among the most common complaints in neurology clinics, and they account for about 13% of the patients entering emergency units. In this Review, we focus on central vestibular disorders, which are mostly attributable to acute unilateral lesions of the bilateral vestibular circuitry in the brain. In a tertiary interdisciplinary outpatient dizziness unit, central vestibular disorders, including vestibular migraine, comprise about 25% of the established diagnoses. The signs and symptoms of these disorders can mimic those of peripheral vestibular disorders with sustained rotational vertigo...

Stefan Evers
Premise This review summarises the pain syndromes that overlap between headache and facial pain and overlap between pain and cranial nerve lesion. Problem These syndromes share two features in common. First, they show both cranial nerve impairment (e.g. palsy, autonomic dysfunction) and pain; second, they have inflammatory (and/or small vessel) processes as the underlying mechanism. A typical representative of these syndromes is recurrent painful ophthalmoplegic neuropathy, which was previously called ophthalmoplegic migraine and was regarded as a migraine subtype...

A 41-year-old female with a history of uterine cancer and Celiac and Raynaud's Disease presented to our institution with frequent migraines and nasal congestion. She underwent functional endoscopic sinus surgery (FESS) and experienced acute unilateral vision loss postoperatively. Rapid recognition of the etiology and effective treatment are paramount given the permanent and irreversible vision loss that can result. Arterial vasospasm following FESS is rare. Patients with autoimmune diseases have perhaps an increased risk for vasospasm secondary to an increased vasoreactive profile...

Parry-Romberg syndrome is a rare disorder characterized by a progressive facial hemiatrophy of the skin, subcutaneous tissue, musculature, bone, and cartilage. It is often associated with neurological symptoms such as trigeminal neuropathy, paresthesia of the face, migraine, and seizures and can be paired with ocular problems and ipsilateral progressive body atrophy. Here, we present a young woman with progressive facial hemiatrophy, who was referred for FDG-PET/CT. Hypometabolism was observed in the left cingulate and postcentral gyrus, left cerebellum, and right basal ganglia...

Few studies have evaluated whether the retina is involved in migraine through the evaluation of retinal nerve fiber layer (RNFL) examined with ocular coherence tomography (OCT) with conflicting results. Aim of this case-control study is to evaluate the retina and the choroid in migraine. Patients having migraine with aura (MwA) or without aura (MoA) and chronic migraine (CM) were evaluated. Age- and sex-matched normal subjects were selected as healthy controls (HC). Patients and HC were examined with OCT. RNFL, ganglion cell layer (GCL), foveal thickness (FT), choroidal thickness (CT) and total macular volume (TMV) were calculated for right eyes (RE) and left eyes (LE)...

Stephen D Silberstein
BACKGROUND: In evidence-based guidelines published in 2000, topiramate was a third-tier migraine preventive with no scientific evidence of efficacy; recommendation for its use reflected consensus opinion and clinical experience. Its neurostabilizing activity, coupled with its favorable weight profile, made topiramate an attractive alternative to other migraine preventives that caused weight gain. When guidelines for migraine prevention in episodic migraine were published in 2012, topiramate was included as a first-line option based on double-blind, randomized controlled trials involving nearly 3000 patients...

PURPOSE: Human beings frequently experience fear, phobia, migraine and hallucinations, however, the cerebral mechanisms underpinning these conditions remain poorly understood. Towards this goal, in this work, we aim to correlate the human ocular perceptions with visual hallucinations, and map them to their cerebral origins. METHODS: An fMRI study was performed to examine the visual cortical areas including the striate, parastriate and peristriate cortex in the occipital lobe of the human brain...

Caloric vestibular stimulation (CVS) to elicit the vestibulo-ocular reflex has long been used in clinical settings to aid in the diagnosis of balance disorders and to confirm the absence of brainstem function. While a number of studies have hinted at the potential therapeutic applications of CVS, the limitations of existing devices have frustrated that potential. Current CVS irrigators use water or air during short-duration applications; however, this approach is not tenable for longer duration therapeutic protocols or home use...
