[The visual functions of patients with traumatic carotid-cavernous anastomoses]

The visual functions in 100 patients with traumatic carotid-cavernous anastomoses were studied. In 54% of cases the visual functions were impaired, in 33% they were lost to various degrees, 21% of patients were practically blind. The most frequent cause of disorders of visual functions were hemodynamic changes in the optic nerve and retina, a less frequent cause was traumatic damage to the optic nerve in its canal. These factors may coexist. The graver the craniocerebral trauma the more probable are sharp loss of visual functions and the development of coarse pathology of the fundus oculi.
