|January 1, 1984
Abstract:
The comportment of placing a swinging pendulum (Pulfrich's phenomenon) in front of three cases of optic nerve head drusen has shown that reduced conductivity is a fact in the optic nerve harboring the drusen, giving oval circular movement. A suggestion is made to use this simple test in patients with this disease.
