Abstract: Objective To discuss the diagnosis, the pathogeny and the corresponding prevention measures of the cortical blindness caused by cerebral angiography. Methods A retrospective analysis was made for the clinical data of the 3 cases of postoperative cortical blindness from 2 467 cases of cerebral angiography in our hospital during January 2002 to December 2017. The pathogenesis and treatment of cortical blindness were discussed in combination with literature analysis.Results The incidence of cortical blindness was 0.12% (3/2 467) in cerebral angiography. The symptoms of 3 patients were alleviated within 5 days after comprehensive treatment including fluid replacement, alleviation of vasospasm, anti-brain edema, corticosteroids, neural nutrition and hyperbaric oxygen. There were no related complications in the 2 follow-up weeks. Conclusion Cortical blindness is a rare complication of cerebral angiography. But most patients can be cured through symptomatic treatment.
