Question

Can central eye movement disorders be a window to brain function?

Answer

A primary attribute for proper functioning in life is gaze stabilization. This enables a subject to track objects, orient in space, and perceive a three-dimensional existence. The process is a complex interplay between peripheral sensors and the brain sending signals thereafter to oculomotor and spinal muscles. The vestibular system plays an important role in gaze stabilization in response to gravity and to motion and connects with vast tracts in the brain that leads to final integration and perception.

Therefore, it is intuitive to understand that eye movements reflect this integration process, and if there are deficits in the system, these movements become abnormal. There are sophisticated computerized gadgets available to measure eye movements and their abnormalities. Since control of eye movements in the brain is highly site and topography specific, different abnormalities indicate the site of lesion in different areas of the brain that are extremely sensitive and may predate imaging findings. To date, more than 50 different eye movements are known, all of which tell a story and lead to a concrete diagnosis of neurological pathology.

SYNAPSYS Video-scope is a new Video-Frenzel system by Inventis fully controllable by the diagnostic software Maestro, which allows video recording of the eye with or without an environmental image and also video playback or extraction. A basic solution for eye movement visualization and analysis. Suitable for both diagnostic and rehabilitation purposes, with SYNAPSYS Video-Scope, the user can choose between a standard wired camera configuration or the flexibility and unique advantages of a wireless system which provides an unprecedented user experience in terms of patient mobility, freedom of movement, and flexibility of use, offering great advantages in performing especially Dix-Hallpike maneuvers.

The introduction of modern tools assessing otolith and ampullary reflexes in the high-frequency domain (VEMPs and video-HIT, respectively) has enabled a fast functional analysis of all inner ear receptors, offering new interpretations for end-organs and afferents abnormalities detected in patients with cochleo-vestibular pathologies. The literature review highlights how vestibular disorders could result in specific lesion patterns, including selective dysfunctions involving a single receptor. A series of patients with isolated impairment of a semicircular canal at the video-HIT will be presented and discussed. Each selective canal dysfunction will be correlated to the remaining clinical-instrumental data and related inner ear pathology. The underlying hypothetical pathomechanism accounting for each single scenario will be provided, with the help of pertinent bibliographic support.

Over the past five years, we have seen a growing interest in studying vestibular disorders in children. The most commonly noteworthy are vestibular disorders in congenital sensorineural hearing loss (SNHL) and cochlear implants. Identifying and diagnosing vestibular and balance dysfunction in children is essential for their overall well-being. However, the diagnosis process is very demanding.This talk will provide an overview of vestibular and balance assessments in children with SNHL.

Vestibular disorders in children are a significant cause of childhood morbidity with various manifestations that are often unrecognized or undiagnosed. The etiological profile, phenotype, and management for peripheral and central disorders are markedly different from that in adults. The diagnostic algorithm with the latest technology is also different as children are far more difficult to obtain anamnesis from and to test as compared to adults. Examining a child is really an art that can come from years of experience and knowledge about the pediatric vestibular system and its development. It is also important to recognize the close overlap with pediatric neurology and indeed, a robust knowledge in neurology is essential to practice pediatric neurotology. This presentation includes an overview of the developing pediatric vestibular system in children, the etiology of pediatric vestibular disorders, the diagnostic process with evidence-based latest methods, and their management. The differences in pediatric vestibular diagnosis and disease profiles are also highlighted from the authors’ personal series.
