Vibrations can induce rupture of zonular fibers.

A case of 'spontaneous' zonular fiber rupture with internal prolapse of the vitreous body without dislocation of the lens is presented. The etiopathogenesis of the lesion is discussed, especially that of the vibrations to which the patient was exposed for more than 10 years. As far as we know, this case is the first description of zonular fiber rupture induced by occupational exposure to vibrations.
