Hydrodynamic events in the vitreous space accompanying eye movements. Significance for the pathogenesis of retinal detachment.

The powers elicited in the vitreous body by eye movements have hardly been subjected to examinations, and the same goes for currents in the vitreous. Model experiments have demonstrated that intra-ocular currents are not elicited by translatory, but so much more by rotatory movements. Furthermore, it is demonstrated that a thin perforated membrane fitted on the inside of the wall of a glass cylinder filled with water, will detach, with rotatory movements. Even minimal rotational movements cause a flow through the hole. It is discussed whether these findings apply to the eye in vivo.
