optic neuritis/nicotina

The vasopressin test gave pathological results in 12 cases of optic atrophy and normal results in three cases. One of the patients with a pathological response had Leber's disease and three had tobacco-alcholic amblyopia, while in the rest the optic atrophy was of uncertain origin. In the cases with

Photopic spectral sensitivities for a foveal target on a white background are measured for 18 normal eyes, and the results are explained in terms of the function of retinal ganglion cells. Averaged results for diseases such as glaucoma, optic atrophy, tobacco amblyopia, and retrobulbar neuritis are
