Excerpt from American Journal of Ophthalmology, 1920, Vol. 3 This essay is the result of the surveys of a number of soldiers undergoing specific treatment in the U. S. Army Base Hospital, Camp Lewis, Washington, 1918 1919, to gether with conclusions drawn from private practice and the literature. A sharp dis tinction is drawn between true choked disc and inflammation of the optic nerve. The former is an edema, the retina being affected secondarily and true inflammation not necessarily taking place; the latter is an inflammatory process in which the contiguous retina is always affected. The paper deals mainly with the ophthalmoscopic findings, time of origin, duration and termination, with suggestions as to treatment. Experience has shown that therapeutic arsenic medication has had no effect upon the production of this lesion. Authority to publish granted, Board of Publication, S. G. O. Neuro-retinitis syphilitica is a speci fic inflammation of the optic nerve and the contiguous retina. There can be no neuritis without an implication of the ret ina, but this in the light cases is con fined to the retinal structures in the immediate neighborhood of the disc, and in others is accompanied by a diffuse retinitis. The inflammation extends into the optic nerve behind the globe to a varying degree in each case. Syphilitic retinitis is always accompanied by more or less papillitis; one or the other may be predominant and thus the lesion in each case may be denominated neuritis or papillitis, retinitis, or neuro-retinitis.
