Key result
Effective CPR may alter the incidence and etiology of cortical blindness.
Why the study?
The incidence and etiology of cortical blindness may be changing with advances in cardiopulmonary resuscitation techniques.
The development of effective cardiopulmonary resuscitation may be changing the incidence and etiology of cortical blindness.
May prompt vigilance for cortical blindness after CPR; leaves open confirmation in larger studies.
The incidence and etiology of cortical blindness--a disorder that usually occurs after cerebrovascular accidents, cardiorespiratory arrest, severe head trauma, or bacterial meningitis--may be changing with the development of effective means of cardiopulmonary resuscitation, as three cases discussed here show.
