On the individual pressure tolerance of the glaucomatous eye.

The individual pressure tolerance of any eye can be determined by taking account of the age, the values of the mean arterial pressure APm, the C/D ratio and the degree of deterioration of the visual field. The method developed opens the way to new possibilities in anti-glaucomatous therapy by making it possible to know the value of the maximum pressure (IPT) which can be supported by the eye under treatment. That treatment must succeed in reducing the value Pi to below the value IPT, if it is to be hoped that the evolution of the glaucoma will be stopped.
