[Contribution of biomechanical and hemodynamic factors to the genesis of chorioretinal dystrophies in myopia].

The bloodflow is decreased in myopic eyes with dystrophic changes in the center and at the periphery, this decrease being in proportion with the severity of the changes. Our study was aimed at elucidating the contribution of the scleral and hemodynamic factors to the genesis of myopic and chorioretinal dystrophies. A total of 295 patients with progressive myopia were examined. The sagittal and frontal sizes of the eye were reliably increased and the rheographic coefficient lowered in complicated progressive myopia as against the condition without complications. The biomechanical factor plays the main role in the pathogenesis of dystrophies.
