This case, which was seen from the first by Alt, is described in the fullest detail and seems to throw a great deal of light as to the manner in which hemorrhages in the retina bring about secondary glaucoma. The eye came to enucleation and was examined carefully in every part, an account of which it is impossible to give here in any detail. The general conclusions, however, which seem to be justified by a careful study of the case are that the disease is primarily one of thrombosis or thrombophlebitis of the larger venous blood-vessels, which leads to rupture of their walls and effusion of blood.
