OBJECTIVE: Symptom factors present during the first week following concussion may predict subsequent concussion outcomes and recovery duration. We hypothesized that a high loading on cognitive-fatigue-migraine and somatic factors would be predictive of neurocognitive impairment following concussion. We also hypothesized that the affective factor would be related to vestibular symptoms and impairment. DESIGN: Prospective repeated measures. SETTING: Concussion specialty clinic...

A common European Community driving licence was established in 1980. However, there are major differences among the countries as regards medical conditions that legally affect driving ability. This article discusses various assessment guidelines for dizzy patients. These range from a total absence of specified binding requirements in Finland or regulations open to clinical interpretation in Switzerland, to inappropriately strict regulations in Germany. We focus on requirements for patients with vestibular disorders in Germany which have been in force since 2014...

Migraine is a common primary headache disorder. The estimated annual prevalence rate of migraine in China is 9.3%. Migraine is typically involved with a series of ocular symptoms including glaucoma, visual performance tests relevant to glaucoma exhibited correlation between glaucoma and migraine. Even though migraine patients exhibit no glaucoma-related signs during intermissions of migraine attacks, the results of visual function tests (visual field, electrophysiology, ocular imaging) relevant to glaucoma still indicate abnormalities...

A 5-year-old girl presented with acute, rapidly progressive encephalopathy following minor head trauma and was found to have ocular dipping. Her encephalopathy was secondary to a channelopathy caused by a CACNA1A mutation. This is the first reported case of ocular dipping in an encephalopathic child with CACNA1A-confirmed hemiplegic migraine. [J Pediatr Ophthalmol Strabismus. 2018;55:e4-e6.].

We aimed to investigate the relationship between contact lens (CL) usage and migraine attacks. Our patient who began using CL with different base curves experienced discomfort and burning of the eyes. The ocular complaints were followed by migraine attacks. The frequency of migraine attacks decreased significantly when the flatter base curve was selected. We assessed the potential causal relationship between CL and migraine.

OBJECTIVE: To systematically review the evidence and make recommendations with regard to diagnostic utility of cervical and ocular vestibular evoked myogenic potentials (cVEMP and oVEMP, respectively). Four questions were asked: Does cVEMP accurately identify superior canal dehiscence syndrome (SCDS)? Does oVEMP accurately identify SCDS? For suspected vestibular symptoms, does cVEMP/oVEMP accurately identify vestibular dysfunction related to the saccule/utricle? For vestibular symptoms, does cVEMP/oVEMP accurately and substantively aid diagnosis of any specific vestibular disorder besides SCDS? METHODS: The guideline panel identified and classified relevant published studies (January 1980-December 2016) according to the 2004 American Academy of Neurology process...

PURPOSE: Migraine is a multifactorial disorder that presents with unilateral headache and several sensory symptoms. Photophobia is one of the ophthalmic manifestations that cause significant morbidity. The trigeminal pathway that innervates the cornea in the form of afferents has been implicated in photophobia associated with chronic migraine. This study investigates changes in the corneal subbasal nerve plexus (SBNP) in chronic migraine patients with and without photophobia. METHODS: Thirty-six patients with migraine and photophobia (group 1), 24 patients with migraine without photophobia (group 2), and 24 age- and sex-matched controls (group 3) were studied...

OBJECTIVE: Previous studies have suggested an association between dry eye and migraine. In a busy ophthalmologist clinic, quick identification of dry eye in migraine sufferers may improve their quality of life. Tear osmolarity is an objective and reliable tool for diagnosing dry eye. It has not been investigated in any population with migraine. Using tear osmolarity and questionnaires, we aimed to explore the relationship between dry eye and clinical symptoms in patients with migraine...

BACKGROUND: Migraineurs, in between headache attacks, have a different sensitivity to sensory motion stimuli compared to non-migraineurs. METHODS: This cross-sectional laboratory study examines the motion processing in migraineurs using ocular following responses (OFR) elicited by large field random dot patterns and open-loop smooth pursuit eye movements (PS) elicited by a single target moving on a homogenous background. Eye movements were recorded with a video-oculographic system (EyeSeeTec® ) and stimuli presented on a CRT at 100 Hz repetition rate to horizontal stimuli of a velocity of 2...
