It affects both eyes, though one is frequently involved before the other. Probably most cases are accom- panied by a gummatous infiltration of the ciliary body and iris. In adults in the acquired form it is often unilateral. Since the disease in the cornea is due to endogenous infection, it begins usually at the corneal margin. There are, however, rare cases with but little opacity and no vas- cularity, which commence near the centre of the cornea and are always accompanied by cyclitis; it is probable that they are due to diffusion of toxin from the aqueous through Descemet's membrane. The spirochaeta paUida has not been demonstrated in interstitial keratitis, partly because so far very few cases have been examined, and partly because the organism is.
