The retinal traction in rabbits has been measured by Kikkawa et al.. The time elapsed from the onset to the disruption can be obtained. Since the rate of traction is known, the amount of elongation of the chorio-retinal complex up to retinal disruption can be calculated. Qualitatively, the amount of the critical elongation of the chorio-retinal complex up to retinal disruption is larger with a high traction rate than with a low traction rate.<BR>For the above experiments, we have taken the three-element mechanical model. The model is stretched with various traction rates and the relation between the rates and the critical elongation in the model is considered. It is shown that the tendency between the retina and the model is similar.<BR>(J. Jpn. Soc. Biorheol., 2(1), 68~71, 1988).
