Retinal tear formation after whole-body vibration training exercise

Abstract

Background: The purpose of this report is to describe the occurrence of a retinal tear, pre-retinal and vitreous hemorrhages after completing a session of whole-body vibration training. Though our patient is the third documented case of vitreous hemorrhage following whole-body vibration training, he is the first to show a close association of a retinal tear and vitreous hemorrhage with whole-body vibration training. Case presentation: This case report describes a 59-year-old male who had acute onset of floaters and shadows in the left eye. The results of the examination revealed a temporal retinal tear, inferior pre-retinal hemorrhage, and mild vitreous hemorrhage. He was successfully treated using laser photocoagulation with resolution of vitreous and pre-retinal hemorrhages on 4-month follow up. Conclusions: With the rise in popularity of whole-body vibration training exercise, it is important for the medical and athletic community to be aware of possible associated ocular complications. We believe that high-force vibration training may cause retinal tears in susceptible persons.

Muscle-to-Brain Signaling Via Myokines and Myometabolites

“…Aerobic exercise also preserves the function and structure of the retina from light-induced degeneration in mice [ 46, 47 ], although other types of exercise can be detrimental [ 48 ]. By acting on the visual cortex, exercise can also correct visual acuity and depth perception in rats with amblyopia [ 49 ] and similar results are also observed in humans [ 50 ].…”

“…Decades of study of vibration in the workplace have established that mechanical signals can be extremely harmful to many human tissues and organ systems. 1 , 7 , 8 , 12 , 19 , 20 , 21 , 22 , 23 , 24 , 26 It is well accepted that Whole Body Vibration (WBV) can result in intervertebral disk displacement, spinal vertebrae degeneration, and osteoarthritis. Vibration transmitted through the spinal column to the head may induce hearing loss, visual impairment, retinal tearing, vestibular damage, and even brain hemorrhaging at very high vibration magnitudes.…”

Efecto agudo del entrenamiento con vibraciones de cuerpo completo sobre la patada circular en atletas de Taekwondo (Acute effect of whole-body vibration training on the roundhouse kick in Taekwondo athletes)

“…Algunos estudios sugieren que frecuencias aproximadas de 30 Hz (De Hoyo et al, 2009;Bush et al, 2015) y amplitudes de 4 mm (Martínez-Pardo et al, 2013;Bush et al, 2015;Donahue et al, 2016) serían propicias para obtener resultados significativos sobre el rendimiento de capacidades físicas como la flexibilidad, la fuerza y la potencia muscular. El uso de frecuencias aún más altas en los estudios con VCC sigue siendo escaso (Galaz-Campos et al, 2021), aunque su uso también debe ser cauteloso, ya que, podría causar desgarros retinianos en algunas personas (Maggiano et al, 2020) o efectos secundarios en personas no entrenadas como vértigo, molestias en las caderas y picazón en miembros inferiores (Lamont et al, 2010). En general, los ejercicios, protocolos y mediciones desarrolladas en estudios similares involucran ciclos de estiramiento-acortamiento ejecutados con las extremidades inferiores (Kurt & Pekünlü, 2015;Oliveira et al, 2018;Aksoy, 2019;Duc et al, 2020).…”
