Disciform degeneration of the macula (Junius-Kuhnt) is a rather common but frequently unrecognized type of senile ocular disease. It is usually bilateral and is characterized by the presence of an elevated mass in the macular region with deep hemorrhages, pigmentary changes and frequently white, punctate areas of degeneration in the surrounding fundus.
The disease is not rare, as is attested by the fact that twelve cases were seen in the ophthalmologic clinic of the State University of Iowa during the past year.
Sclerosis of the choroidal vessels, occurring with generalized vascular disease, is believed to cause metaplasia and hyperplasia of the pigment epithelium with the formation of a mass resembling connective tissue between the choroid and the retina.
Loss of central vision invariably accompanies the disease ; it usually comes on rather rapidly and progresses over a period of weeks or months until only large objects are visible. A central scotoma
