Meyer), and succeeds only in those cases in which one or the other bundle of ciliary nerves is manifestly irritated, and the second eye is becoming involved; it must, however, necessarily fail where the ciliary body is completely involved in the cyclitic process , and where this is indicated by the sensitiveness to palpation at every single point of the anterior scleral zone.
