The clinical and histopathologic features of 29 eyes from 29 @entity1 with central @entity2994 (CRVO) are reported. A fresh or a recanalized @entity715 was observed in each eye. This study considers the temporal aspects of the cases, and it notes the different morphologic features of the occlusion. These observations explain most of the variability of the changes observed in previous reports. We believe that these different features represent the various stages in the natural evolution of such a @entity715 . The interval between CRVO and histopathologic study in our series ranged from six hours to more than 10 years. Local and systemic factors were reviewed and were found to be important in the pathogenesis of @entity715 formation. @entity66 with a predisposing effect on CRVO included: @entity726 , @entity1829 , @entity548 , @entity548 , and drusen of the optic nerve head. Associated systemic diseases included: @entity101 , @entity65 , @entity6 , and @entity1778 with @entity882 . A fresh @entity715 in the CRVO was observed in three (10.3%), and a recanalized @entity715 in 26 eyes (89.7%). Endothelial-cell proliferation was a conspicuous feature in 14 (48.3%) of the eyes. @entity32 in the area of the @entity715 , and/or vein wall or perivenular area was observed in 14 (48.3%) of the eyes. @entity432 was observed in seven eyes (24.6%). @entity1103 was found in 26 (89.7%) of the eyes.
