Two years later, she came in saying that she had just hadan attack, which had started a few hours before in the othereye. The vision in that eye was less than ^q\, and therewas a general haze over the temporal region. With theophthalmoscope, I saw, passing from the disc, a cilio-ret-inal artery, going out to the macular region. For a smallportion of its extent, on the disc and beyond the disc, thisartery was absolutely occluded and thread-like. I triedmassage, and sent for nitrite of amyl.

I examined the patient while she wastaking it, and I saw the vessel actually dilate under my eyesuntil it filled to a normal size. The vision from less than2-V^o returned to practically normal. No test was made ofthe blood-pressure, except by feeling the pulse with thefinger and with this there seemed to be no change, the pulsebeing normal in fulness and tension.
