In 1893, Gowers1 gave unilateral loss of sight and of smell as a lateralizing sign of frontal tumor. In 1905, Schultz-Zehden2 published a clinical and postmortem report of a frontal tumor with profound optic atrophy in one eye and severe papilledema in the other. He stated, "We have before us in the foregoing case, a double action by the tumor. In the one eye it led to atrophy by direct compression of the optic nerve; in the other it acted directly to destroy it by raising the intracranial pressure." In 1906, Wilbrand and Saenger3 reported a similar case and explained that the absence of papilledema in the atrophic nerve head was due to the shutting off by the tumor of the meningeal spaces, thus preventing the cerebrospinal fluid from circulating into the optic nerve sheath on that side.
In 1909, Leslie Paton4 wrote his famous paper
