[Incomplete central vein occlusion. A clinicopathologic case report].

A 71-year-old patient died 4 weeks after the occurrence of incomplete occlusion of the central retinal vein. Histology of the two bulbi was compared with the photographic and fluorescenceangiographic findings of the fundus. Histologic evaluation showed that the occlusion had been caused by a thickening of the vein wall due to proliferation of fibrocytes and histiocytes just behind the lamina cribrosa. There were no signs of phlebitis or thrombosis.
