Poor vision and visual field changes, particularly a central scotoma, are characteristic features of most cases of retrobulbar neuritis. It is remarkable in this type of disease that no changes can be found ophthalmoscopically in the fundus, at least at the beginning stage of the disease.
In the present paper we shall report on the behavior of critical fusion frequency of flickering light (CFF) in patients with retrobulbar neuritis. Experiments were carried out with special reference to the CFF at the retinal region corresponding to the central scotoma.
There can be found only a few reports which are concerned with the CFF in retrobulbar neuritis.1 In a number of cases of diseases of the optic nerve, some of which may belong to the type of retrobulbar neuritis, Braunstein,2 Riddell,3 Hylkema,* and others found that the CFF was decreased more or less at the area of deteriorated vision.
