The intraocular pressure equalled 15 mm. Hg. Her only medication was one-percent pilocarpine, three times daily. Diffuse and sector-shaped iris atrophy following glaucomatous attacks has been widely seen; occasionally localized periph­ eral iris atrophies, especially in connection with deep iris crypts, have shown remedial effects equal to peripheral iridectomies. However, in all these cases at least a part of the chamber angle was found to be open. In the case presented the chamber angle seems to be completely closed and an improvement of the out-flow mechanism hardly could ex­ plain the spontaneous reduction in tension. The question therefore arises: if a simul­ taneous atrophy of the ciliary body and de­ creased formation of aqueous in combina­ tion with an almost complete loss of fluid ex­ change from the iris surface could be the cause of the (probably only temporary) re­ duction of the intraocular pressure. Tonographic studies would be essential for evalu­ ation of the presently existing hypotension and an explanation of its possible origin.

In the macula there was a yellowish white lesion two to three disc diameters in size, elevated three diopters. The mass was smoothly rounded, but the surface was crinkled. The borders were fairly clearly demarcated. The retinal vessels passed over the mass unchanged, except for being ele­ vated. When seen two months later, the mass was larger, the borders less regular, and there was a dark spot of deep hemor­ rhage at the upper medial border. It was felt that the lesion was a degenera­ tive one of vascular origin. Continued ob­ servation and photographs at monthly or longer intervals were advised. Treatment was thought to be useless.
