Retinal vein occlusion and glaucoma. Tonographic study of the incidence of glaucoma and of its prognostic significance.

PREsENT thinking about the relations between central retinal vein occlusion and glaucoma derives mainly from the pioneer work of Verhoeff (1913), Salzmann (1933), and Duke-Elder (1940, 1957, 1959). Since their papers on this subject many reports have been added to the literature. Recently, Landolt (1958) has published his work on histology and Dobree (1957) clinical studies on the incidence of central retinal vein occlusion in glaucoma patients. The incidence of glaucoma has been studied at this hospital in a series of patients with retinal vein occlusion. Both central vein and branch occlusions were included, and since most of these subjects have been treated as inpatients at our hospital, the prognosis of the glaucoma also entered into the question. To the best of our knowledge, no similar studies employing tonography have been published.
